Smartphone Micromax Canvas Juice A1 (Q4251): budget model with a long battery life. Packaging and equipment
Content
Micromax is not only one of the leading electronics manufacturers in India, but also a major player in the global mobile phone market. In Russia, the Indian company settled a long time ago, so today we will talk about certified products that are officially supplied to our market. Having decided on the main priorities, in October last year, Micromax announced a strategy to bring to Russian market new lines, Warrior and Juice. Each line is different key feature: the Warrior line has an affordable price, while the Juice line has capacious batteries and, accordingly, a long time battery life. The novelties of the coming year in the Warrior and Juice lines are the inexpensive Micromax Bolt Warrior 2 (Q4202) and the Micromax Canvas Juice A1 (Q4251) smartphone with a powerful 4000 mAh battery.

Contents of delivery
Micromax Canvas Juice A1 comes in a fairly large flat square box with a hard cardboard dust jacket. Packaging different smartphones companies are distinguished by this dust jacket, on which all designations, logos and specifications are applied, and the inside remains absolutely clean and the same in all cases.
The scope of delivery consists of a connecting cable, a powerful network adapter with an output current and voltage of 2 A 5 V, a wired headset with in-ear rubber pads, a protective film on the screen and paper instructions in Russian.
Appearance and usability
For external design of their mobile novelties in the new season, Micromax artists chose a single and rather peculiar design. It is slightly rough, uncomplicated, a kind of industrial type of design, where straightforward practicality prevails over the fashion component and where smooth metal is used in combination with rubberized plastic.
The case as a whole is not metal, for the most part it consists of plastic, only the central part of the back cover is made of real metal: it is a thin plate soldered into a plastic frame. All sidewalls, end parts, as well as the upper and lower rear inserts are made of plastic.
A little metal is added here rather for decoration, since from a practical point of view, any parts of the case will wear out and break over time - the ends, edges, even the front glass - but not the middle of the back side. Yes, and upon impact, this plate, soldered into plastic, will rather fall off by itself than play any protective role, since it has nothing to do with the rigidity contour.
The device is quite thick and heavy, the reason for this is a very voluminous accumulator battery at 4000 mAh, so the increased weight here is generally justified. The plastic sidewalls have a ribbed texture, so the smartphone does not slip at all in the hands. We can't call the case easily visible either, fingerprints here can be seen only on the front glass.
The dimensions of this five-inch device can not be called large, and thanks to the thick body with side rounding of the back cover, the case fits securely and comfortably in your hand. However, for a trouser pocket, its mass of almost 180 grams is still quite noticeable.

In order to get to the card slots, you need to remove back cover. There is no special protrusion for engagement, you will have to rest against the cutout for the Micro-USB connector. The cover can be removed quite easily, there are no problems with this, but it is also surprisingly securely held on its plastic latches, the body as a whole is solid and strong, there is no backlash or squeaks when compressed.
Connectors for all three cards are quickly and conveniently accessible, and it's easy to insert cards in adapters into them, but here they may be needed, since both slots are designed for the outdated Micro-SIM format. One of the connectors is made in an old-fashioned version with a cover that opens upwards, pressing a SIM card, and the other two - for the second SIM card and memory card - are assembled in a sandwich one above the other. All three slots are available simultaneously and are completely independent of each other.
It is curious that although you do not need to remove the battery to access all three connectors, including the memory card, hot-swapping is still not supported here. The device will not react in any way to any of the inserted cards until you reboot the device yourself. This is a rather rare option, especially considering that the battery is not removed here in principle.
The camera module does not protrude beyond the surface, and thanks to the almost flat back wall, the smartphone does not sway when touching the screen, it lies steadily on the table. The flash next to the camera is single-segment, its brightness level can be described as below average.
The main speaker is brought here, on the back of the case, and this, of course, is not good, since the sound of the device lying with the screen up is noticeably muffled.
The side buttons are installed on the right side, the keys are large, stick out to a sufficient height, have a rather hard move and a distinct response. It is quite possible to get used to a little excessive rigidity of pressing.
The front panel is covered with flat glass without sloping edges. At the top there is a light sensor, a camera without a flash, but, unfortunately, no LED indicator events. There is also no backlight at the bottom, since there are no hardware buttons there.
Interface connectors are standardly placed on the ends: the top one is given over to a 3.5 mm headphone output.
At the bottom end asymmetrically, closer to one of the edges, there is a hole for the Micro-USB connector, connection is supported external devices in USB OTG mode.
Micromax Canvas Juice A1 is available in two color options: gray with a black side rim and black front panel, as well as gold, in which the front panel is golden, but the side rim is also black.
Screen
The Micromax Canvas Juice A1 features a 62x110mm On-cell IPS touch display with a 5-inch diagonal protected by a flat protective glass without sides and sloping edges. The screen resolution is 1280×720, the dot density is about 294 ppi. You can’t call the frame around the screen narrow: it is a little less than 5 mm on the sides, and all 18 mm on the bottom.
Display brightness can be adjusted manually or set automatic settings based on the operation of the ambient light sensor. The AnTuTu test diagnoses support for 5 simultaneous multitouch touches. There are no additional ways to activate the display using a double click or other gestures.

Detailed examination using measuring instruments held the editor of the sections "Monitors" and "Projectors and TV" Alexey Kudryavtsev. Here is his expert opinion on the screen of the test sample.
The front surface of the screen is made in the form of a glass plate with a mirror-smooth surface, resistant to scratches. Judging by the reflection of objects, the anti-glare properties of the screen are better than those of the Google Nexus 7 (2013) screen (below is just Nexus 7). For clarity, here is a photo in which a white surface is reflected in the off screens (on the left is Nexus 7, on the right is Micromax Canvas Juice A1, then they can be distinguished by size):
The screen of Micromax Canvas Juice A1 is darker (brightness in photos is 104 versus 114 for Nexus 7). The ghosting of reflected objects in the Micromax Canvas Juice A1 screen is weak, which indicates that there is no air gap between the screen layers (more specifically, between the outer glass and the surface of the LCD matrix) (OGS type screen - One Glass Solution). Due to the smaller number of borders (glass/air type) with very different refractive indices, such screens look better in conditions of intense external illumination, but their repair in case of cracked external glass is much more expensive, since the entire screen has to be changed. On the outer surface of the screen, there is a special oleophobic (grease-repellent) coating, which is noticeably worse in efficiency than the Nexus 7, but still fingerprints are removed more easily and appear at a slower rate than in the case of ordinary glass.
With manual brightness control and with a white field displayed in full screen, the maximum brightness value was about 420 cd/m², the minimum was 30 cd/m². The maximum brightness is not very high, but given the excellent anti-glare properties, on a sunny day outdoors on this screen you can see something. In complete darkness, the brightness can be reduced to a comfortable value. In the presence of automatic brightness control by light sensor (it is located to the left of the front speaker slot). AT automatic mode as the ambient light conditions change, the brightness of the screen both increases and decreases. This function depends on the position of the brightness slider. If it is at 100%, then in complete darkness the auto-brightness function reduces the brightness to 150 cd / m² (very bright), in an artificially lit office (about 550 lux) it sets it to 420 cd / m² (too high), in a very bright environment ( corresponds to lighting on a clear day outdoors, but without direct sunlight - 20,000 lux or a little more) the brightness increases to the same 420 cd / m² (to the maximum - that's right); if the adjustment is about 50%, then the values are as follows: 30, 420 and 420 cd / m² (the average value is again too high), the regulator at 0% is 30, 420 and 420 cd / m² (all the same). It turns out that the auto-brightness function does not work quite adequately. At any brightness level, there is no significant backlight modulation, so there is no screen flicker.
AT this smartphone IPS type matrix is used. In the micrograph, you can see the subpixel structure typical of IPS:
For comparison, you can see the gallery of microphotographs of screens used in mobile technology.
The screen has good viewing angles without significant color shift even at large deviations of the gaze from the perpendicular to the screen and without inverting shades. For comparison, here are photos in which the same images are displayed on the Micromax Canvas Juice A1 and Nexus 7 screens, while the screen brightness is initially set to about 200 cd / m², and the color balance on the camera is forcibly switched to 6500 K.
White field perpendicular to the screens:
Note the good uniformity of brightness and color tone of the white field.
And a test picture:
Colors on the Micromax Canvas Juice A1 screen have a natural saturation, the color balance of the Nexus 7 and the tested screen differs markedly.
Now at an angle of about 45 degrees to the plane and to the side of the screen:
It can be seen that the colors did not change much on both screens, but on the Micromax Canvas Juice A1, the contrast decreased to a greater extent due to the strong whitening of blacks and the decrease in image brightness.
And the white box:
The brightness at an angle of the screens has decreased (at least 5 times, based on the difference in shutter speed), but the Micromax Canvas Juice A1 screen is noticeably darker. The black field, when deviated diagonally, is highlighted strongly and acquires a reddish or red-violet hue. The photos below demonstrate this (the brightness of the white areas in the direction perpendicular to the plane of the screens is the same!):
And from another angle:
When viewed perpendicularly, the uniformity of the black field is poor:
Contrast (approximately in the center of the screen) is high - about 1000:1. The response time for the black-white-black transition is 20 ms (10 ms on + 10 ms off). The transition between grayscale 25% and 75% (according to the numerical value of the color) and back in total takes 38 ms. The gamma curve constructed from 32 points with an equal interval according to the numerical value of the shade of gray did not reveal a blockage either in the highlights or in the shadows. The exponent of the approximating power function is 2.18, which is close to the standard value of 2.2. In this case, the real gamma curve slightly deviates from the power dependence:
We did not find the presence of dynamic adjustment of the backlight brightness in accordance with the nature of the displayed image, which is very good.
Color gamut close to sRGB:
The spectra show that the matrix filters moderately mix the components to each other:
As a result, the colors have a natural saturation. The balance of shades on the gray scale is acceptable, since the color temperature is significantly higher than the standard 6500 K, but the deviation from the blackbody spectrum (ΔE) is less than 10, which is considered an acceptable indicator for a consumer device. At the same time, the color temperature and ΔE change little from shade to shade - this has a positive effect on the visual assessment of color balance. (The darkest areas of the gray scale can be ignored, since the color balance does not matter much there, and the measurement error of color characteristics at low brightness is large.)
To summarize: the screen has a fairly high maximum brightness and has excellent anti-glare properties, so the device can somehow be used outdoors even on a sunny summer day. For conditions of complete darkness, it is possible to set a comfortable level of brightness. The mode with automatic brightness adjustment is present, but it does not work well. The advantages of the screen include the absence of an air gap in the layers of the screen and flicker, high contrast, as well as a color gamut close to sRGB and an acceptable color balance. Among the significant shortcomings, we rank the poor uniformity of the black field and the low stability of black to the deviation of the gaze from the perpendicular to the screen plane. Given the importance of the characteristics for this particular class of devices, the screen quality is relatively high.
Camera
The front camera of the Micromax Canvas Juice A1 received a module with a resolution of 2 megapixels and a lens with an aperture of f / 2.8 without autofocus and its own flash. The shooting quality is rather modest even for the level of a selfie: with such a low level of detail, other characteristics will not play a serious role.
 |
 |
The main camera has a module with a resolution of 8 megapixels and a lens with an aperture of f / 2.2 (for some reason, the official specifications on the Russian site indicate a resolution of 5 megapixels). Autofocus is quite fast, the flash is not very bright, there is no stabilization function. The settings menu here is non-standard, it is much more convenient than the original one from the Android interface, visual and very easy to use. The menu structure is concise: pops up on the left vertical list with the main sections, clicking on each of which expands a second scroll to the right with options related to that function. Handy, but the camera has a strange "stickiness" when it continues to take 6 MP (2448x2448) square shots, even if the maximum resolution of 8 MP (2448x3264) is selected in the menu at that moment. As a result, only a complete reset of the device to the factory settings helped us, after which the camera began to behave adequately.
There are not many manual settings in the menu, but everything you need is available. You can manually set exposure, ISO (up to ISO 1600), white balance, shutter speed, select additional modes and color effects, there is HDR. There were no such familiar features as face detection, smiles and the ability to shoot by gesture. It is impossible to transfer control of camera settings to third-party applications using the Camera2 API, and there is also no possibility of recording pictures in RAW.

The camera can shoot video at a maximum resolution of only 720p, there are no shooting modes at 60 fps, not only 4K, but even Full HD. There is also no stabilization function. The video camera shoots accordingly: miracles do not happen, and it is impossible to achieve good detail from a resolution of 720p. The image is loose, but bright and smooth, without noticeable artifacts, with natural color reproduction. When recording audio in a noisy street, the familiar distortions of echoes and gurgling sounds may appear. With a less noisy sound background, distortion does not appear. Nothing is officially said about the presence of a noise reduction system in this smartphone.

Good sharpness across the field of the frame and according to the plans. |
 |
Good detail in the background. |
 |
The camera does a good job with shadows. |
 |
The immediate plans worked out well. |
 |
The camera copes with macro photography. |
 |
There are small areas of blur in the corners. |
The camera turned out pretty good. The optics give decent sharpness across the field of the frame and according to the plans, and software processing does not spoil the details, even small ones, although in places it is noticeable. As a result, the camera can be used for documentary shooting, and sometimes for undemanding art.
Telephone part and communications
The communication capabilities are as follows: the smartphone can work in 4G networks thanks to the Snapdragon X5 LTE modem, which allows you to receive data at speeds up to 150 Mbps and give up to 50 Mbps (LTE Cat.4). The device operates in all three most common LTE FDD bands in Russia. At the same time, only one Wi-Fi band (2.4 GHz) is supported and there is no NFC. All wireless modules, including Wi-Fi, behave quite confidently, no problems with registration in networks, unexpected loss of signal, and the like were noticed.
The navigation module, thanks to the Qualcomm platform, supports all three satellite systems - GPS, Glonass and BeiDou. The module is slow, the first satellites are detected during a cold start for more than a minute. Magnetic field sensor, on the basis of which it usually functions digital compass navigation programs, the smartphone, unfortunately, was not equipped. Micromax Canvas Juice A1 is not rich in sensors at all: there are only light and proximity sensors and an accelerometer.

The phone app supports Smart Dial, while dialing telephone number immediately carried out and the search for the first letters in the contacts. AT phone book there are only regular options for setting up the display of contacts. There is no built-in blacklist, but the automatic recording function telephone conversations from the line is present. In conversational dynamics, the sound is muffled, there is a slight effect, as if the interlocutor is “speaking into the pipe”, but in general, a familiar voice remains recognizable. The vibrating alert unexpectedly turned out to be above average in strength, it is quite noticeable, but manual settings does not have.

The smartphone platform does not support work with two SIM-cards in 3G / 4G at the same time, that is, SIM-cards of such operators as Tele2 will not work in 3G for voice communication if a card from another slot is assigned for data transmission in 4G (in 2G Tele2 cards simply do not know how to work). The standard interface allows you to select a specific card for each of the functions in advance or directly during the connection. Cards work in Dual mode SIM Dual Standby, there is only one radio modem.

Initially, a rather large number of additional programs. Some of them are useful, such as file manager, navigator 2GIS, office suite WPS Office, but most of them are free simple games or demos of better games. All these applications, if desired, can be downloaded independently, that is, basically they are free garbage, which only clogs the already catastrophically small storage. It's good that any third party applications can be manually removed without any problem. The standard keyboard supports stroke type Swype.

To listen to music, a music player is designed with a pleasant-looking interface and fairly rich settings for the built-in equalizer. You can manually influence bass saturation and surround sound virtualization. The sound quality is average, it corresponds to the level of the device: both in the headphones and in the main loudspeaker, the sound is quite loud, clear, but unpretentious, unsaturated, monophonic, with a predominance of high frequencies. If you manually add bass using the equalizer, then the sound becomes muffled, less sonorous.
The built-in microphone does not shine with special sensitivity, but the recorder records sound sources located close to each other quite well. There is a built-in FM radio with the ability to record programs from the air, there are no complaints about its sensitivity, the radio works properly.

Performance
Micromax Canvas Juice A1 hardware platform builds on SoC entry level Qualcomm Snapdragon 210, made using the 28 nm process technology. The configuration of this chip includes 4 Cortex-A7 processor cores operating at a frequency of up to 1.1 GHz. The video accelerator Adreno 304 with a frequency of up to 400 MHz is responsible for graphics processing. The amount of RAM is 1 GB (LPDDR3), in reality, about 400 MB of them remain free. User storage initially is only 3.57 GB out of a total of 8 GB, that is, you can’t do without a memory card here.
 |
 |
Qualcomm Snapdragon 210 - SoC is very simple, even some alternative entry-level platforms show better results in tests, including the popular on this moment manufacturers MediaTek MT6737. The Snapdragon 210 is equipped with low-power, low-frequency Cortex-A7 processor cores and the same entry-level video accelerator.
However, in real work, there were no serious problems in the operation of the interface and applications. The device adequately copes with its main tasks, the desktops scroll without sticking, applications open quickly, the interface does not “slow down”. I even managed to play popular, albeit not the most recent games, such as Dead Trigger 2, World of Tanks, at minimum settings without noticeable slowdowns. However, the user should clearly understand that without additional purchased microSD cards in this smartphone for such purposes will constantly lack memory.
Testing in comprehensive AnTuTu and GeekBench tests:
For convenience, we have summarized all the results obtained by us when testing a smartphone in the latest versions of popular benchmarks in tables. Several other devices from different segments are usually added to the table, also tested on similar latest versions benchmarks (this is done only for a visual assessment of the obtained dry numbers). Unfortunately, within a single comparison, it is impossible to present the results from different versions benchmarks, so many worthy and relevant models remain “behind the scenes” - due to the fact that they once passed the “obstacle course” on previous versions test programs.

Testing the graphics subsystem in 3DMark gaming tests, GFXBenchmark and Bonsai Benchmark:
When testing in 3DMark for the highest performing smartphones, it is now possible to run the application in Unlimited mode, where the rendering resolution is fixed at 720p and VSync is disabled (due to which the speed can rise above 60 fps).

Browser cross-platform tests:
As for benchmarks for assessing the speed of the javascript engine, you should always make allowances for the fact that the results in them depend significantly on the browser in which they are launched, so that the comparison can only be truly correct on the same OS and browsers, and this possibility is available when testing not always. In the case of Android OS, we always try to use Google Chrome.

AndroBench memory performance test results:
thermal images
Below is a thermal image rear surface obtained after 10 minutes of running a battery test in the GFXBenchmark program:
It can be seen that the heating is localized in the upper part of the device, which apparently corresponds to the location of the SoC chip. According to the heat chamber, the maximum heating was 36 degrees (at an ambient temperature of 24 degrees), which is relatively small.
Video playback
To test the "omnivorous" when playing video (including support for various codecs, containers and special features, such as subtitles), we used the most common formats, which make up the bulk of the content available on the Web. Note that for mobile devices it is important to have support for hardware video decoding at the chip level, since it is most often impossible to process modern versions using processor cores alone. Also, you should not expect everything from a mobile device to decode everything, since the leadership in flexibility belongs to the PC, and no one is going to challenge it. All results are summarized in a table.
According to the test results, the test subject, as is often the case, was not equipped with all the necessary decoders that are needed to fully play most of the most common multimedia files on the network, in this case, sound ones. To successfully play them, you will have to resort to the help of a third-party player - for example, MX Player. True, it is also necessary to change the settings in it and manually install additional custom codecs, because now this player does not officially support the AC3 audio format.
| Format | container, video, sound | MX Video Player | Regular video player |
| 1080p H.264 | MKV, H.264 1920×1080, 24fps, AAC | plays normally | plays normally |
| 1080p H.264 | MKV, H.264 1920×1080, 24fps, AC3 | not playable | |
| 1080p H.265 | MKV, H.265 1920×1080, 24fps, AAC | plays normally | plays normally |
| 1080p H.265 | MKV, H.265 1920×1080, 24fps, AC3 | video plays with delays, no sound | not playable |
Further testing of video playback performed Alexey Kudryavtsev.
We did not find the MHL interface, as well as Mobility DisplayPort, in this smartphone, so we had to limit ourselves to testing the output of video files on the screen of the device itself. To do this, we used a set of test files with an arrow and a rectangle moving one division per frame (see "Methodology for testing video signal playback and display devices. Version 1 (for mobile devices)" Red marks indicate possible problems associated with playback of the corresponding files.
According to the criterion for displaying frames, the quality of playing video files on the screen of the smartphone itself is good, since in most cases frames or groups of frames can (but are not required) to be displayed with more or less uniform alternation of intervals and without frame drops. When playing video files with a resolution of 1280 by 720 pixels (720p) on a smartphone screen, the image of the video file itself is displayed exactly along the border of the screen, one to one in pixels, that is, in its original resolution. The range of brightness displayed on the screen corresponds to the standard range of 16-235: all gradations of shades are displayed in the shadows and in the highlights.
Battery Life
The non-removable battery installed in the Micromax Canvas Juice A1 has a large capacity of 4000 mAh, and this is the main trump card of this model. The device logically demonstrates very high level autonomy, the results in all tests are impressive. And if you take into account the undemanding SoC and the screen with a low resolution, then in real operating conditions the smartphone will adequately cope with daily tasks for a couple of days without recharging. In general, such a smartphone is indispensable on a long journey, which was emphasized. But everything, of course, will depend on your use case. The developers themselves promise up to 6 hours of talk time and up to 350 hours of standby time, and this is generally close to the truth.
Testing has traditionally been conducted at normal power levels without power saving features.
Continuous reading in the Moon + Reader program (with a standard, light theme) at a minimum comfortable brightness level (brightness was set to 100 cd / m²) with auto scrolling lasted until the battery was completely discharged for 19 hours, and with continuous viewing of video in high quality (720p) with same brightness level through home wifi network the device operates for about 14 hours. In 3D gaming mode, the smartphone worked for 7 hours.
At the same time, the bulky battery charges quite quickly: the battery is completely filled from the supplied AC adapter in just over 2.5 hours with a current of 1.9 A at a voltage of 5.5 V. Wireless charging is not supported.
Outcome
Micromax Canvas Juice A1 is already available in official Russian retail at a price about 8 thousand rubles. Someone may consider this price too high for a smartphone, which, at least, still needs to buy a memory card. The Micromax Canvas Juice A1 has an entry-level hardware platform (but still Qualcomm) and modest sound capabilities, a high-quality fairly bright screen, an unexpectedly decent camera for its level, as well as a basic set of communication capabilities with support for three navigation systems and all frequencies common among Russian operators. LTE. The device is solid, with a practical case, there are not enough stars from heaven, but as a reliable workhorse with a guaranteed long battery life, it may well arouse interest in a certain part of the audience for which these qualities come first.
For those who lack the fingerprint authorization function, an improved modification of this model was later announced, called the Micromax Canvas Juice A1 plus (Q4260). It is curious that it is not only equipped with a fingerprint sensor, but also works on a different hardware platform - MediaTek MT6737V with a frequency of processor cores up to 1.25 GHz (but the same 1 GB random access memory). Apparently, it will be a slightly more productive model, but it will also cost a thousand more than the original.
In conclusion, we suggest watching our video review of the Micromax Canvas Juice A1 (Q4251) smartphone:

Packaging and equipment
The device comes in a stylish black and white box. The lid is marked strengths smartphone - the sound is three times louder than normal and increased capacity battery (in the word “Juice” the letter I is depicted in the form of a battery with a full charge).
Inside the box are a protective film for the screen, a headset in the shape vacuum headphones, charger and microUSB cable⇔ USB.
Design and ergonomics
The Micromax Canvas Juice 2 has nothing superfluous in its design: it is a classic five-inch smartphone with rounded back edges and a removable cover that hides the slots for two SIM cards and a microSD memory card.
The front panel is completely covered with glass, it contains a display, a front camera, a round speaker, and a light indicator. System control buttons (“Back”, “Menu”, “Home”) are built into the interface and located at the bottom of the screen.
The hardware power button and volume rocker received the most convenient, familiar to most users location - on the right edge, in its upper part. The buttons are firm enough for comfortable use and have a clear stroke.
The device lies perfectly in the hand, and the texture of the back panel does not allow it to slip out.
The smartphone is assembled soundly. Despite the fact that the parts are made of plastic (and, unlike metal, it is very difficult to customize), there are no backlashes or gaps.
Device in operation
The Micromax Canvas Juice 2 is powered by a MediaTek MT6580 quad-core processor clocked at up to 1.3GHz. The graphics accelerator Mali-400 MP is responsible for the graphics. The amount of internal storage was 8 GB, RAM - 2 GB. This filling provides the smartphone with good performance when performing everyday tasks: as a rule, the system responds to user actions quickly. There are occasional stutters, but they are more related to optimizing specific applications than insufficiently fast hardware.
The result of Micromax Canvas Juice 2 in the AnTuTu benchmark.
The speaker sound of the Micromax Canvas Juice 2 is very loud and, importantly, without noticeable distortion at full volume. There are lower frequencies (bass). So games, movies, music - all kinds of multimedia entertainment are perfectly combined with this device.
In addition, the novelty has a clear screen with HD resolution and no pixelation. It was created using IPS technology, which provides high brightness, contrast and good viewing angles with relatively low power consumption. Touchpad recognizes five simultaneous touches.
Interface
The device runs on Android 5.1 Lollipop. There is no additional launcher, so the user has access to a “clean”, not overloaded, Android. There are no extra pre-installed applications on the smartphone out of the box either, so after the purchase you won’t have to waste time removing unnecessary software. You can immediately start installing the set of programs that will be useful to you personally.
In the settings there is a set of MiraVision tools that allows you to adjust the clarity, saturation, contrast and color temperature of the image on the screen.
Camera
The 8-megapixel camera module mounted on the Micromax Canvas Juice 2 is equipped with a flash and auto focus. It delivers excellent photography results in all conditions, including focusing on close subjects with ease. When shooting at night, the shots are also sharp and not blurry, with natural color reproduction.
The camera is equipped with an HDR mode that expands the dynamic range of shots and enhances the detail in the lightest and darkest dark areas. This feature works best in backlit situations, compensating for the high contrast in such shots.
HDR mode is off: the object in the foreground is not detailed enough, there are “gaps” in the shadows.
HDR mode on: the foreground is brighter and sharper.
Offline work
The battery of Micromax Canvas Juice 2 is simply huge - 4000 mAh. Its charge can be stretched for five days if you turn off GPS and Wi-Fi and limit the use of the screen. By “chasing” it to the fullest (as smartphone owners usually do), we almost completely discharged the gadget in two days. This is an excellent result, which means that the autonomy of the Micromax Canvas Juice 2 is really above average.
Results
The Micromax Canvas Juice 2 is a well-balanced device that is worth the money. The only thing it lacks is LTE support. Otherwise, the manufacturer managed to find a good balance between price and quality, equipping the gadget with a clear screen, 2 GB of RAM, excellent speakers and, most importantly, an unusually capacious battery.
Accelerometer(or G-sensor) - device position sensor in space. As a main function, the accelerometer is used to automatically change the orientation of the image on the display (vertical or horizontal). Also, the G-sensor is used as a pedometer, it can be controlled by various functions of the device by turning or shaking.
Gyroscope- a sensor that measures the angles of rotation relative to a fixed coordinate system. Able to measure rotation angles in several planes simultaneously. The gyroscope together with the accelerometer allows you to determine the position of the device in space with high accuracy. In devices that use only accelerometers, measurement accuracy is lower, especially when moving quickly. Also, the capabilities of the gyroscope can be used in modern games for mobile devices.
Light sensor- sensor, thanks to which the optimal values of brightness and contrast are set for given level illumination. The presence of the sensor allows you to increase the operating time of the device from the battery.
Proximity sensor- a sensor that detects when the device is close to the face during a call, turns off the backlight and locks the screen, preventing accidental pressing. The presence of the sensor allows you to increase the operating time of the device from the battery.
Geomagnetic sensor- a sensor for determining the direction of the world in which the device is directed. Tracks the orientation of the device in space relative to the Earth's magnetic poles. The information received from the sensor is used in mapping programs for orientation in the area.
Atmospheric pressure sensor- sensor for accurate measurement of atmospheric pressure. It is part of the GPS system, allows you to determine the height above sea level and speed up the location.
touch ID- Fingerprint identification sensor.
Accelerometer / Illumination / Approximation
GPS(Global Positioning System - global positioning system) - satellite system navigation that measures distance, time, speed and determines the location of objects anywhere on the Earth. The system was developed, implemented and operated by the US Department of Defense. The basic principle of using the system is to determine the location by measuring the distances to the object from points with known coordinates - satellites. The distance is calculated from the signal propagation delay time from sending it by the satellite to receiving it by the GPS receiver antenna.
GLONASS(Global Navigation Satellite System) - Soviet and Russian satellite navigation system, developed by order of the USSR Ministry of Defense. The principle of measurement is similar to the American system GPS navigation. GLONASS is intended for operational navigation and time support for land, sea, air and space-based users. The main difference from the GPS system is that GLONASS satellites in their orbital movement do not have resonance (synchronism) with the Earth's rotation, which provides them with greater stability.
