Cause of background noise in mobile phone. Five signs that your cell phone is being tapped
It's no secret that a mobile phone can become an object of surveillance for a certain person, who can thus spread confidential information. Especially dangerous is listening to a mobile phone with the help of spyware that quietly "settled" on your mobile device. And while you are calmly talking on the phone, someone will use you to expose important information, whether it's your personal life or the confidential data of the company you work for.
While there are scandals in the United States and reports that another Russian intelligence group of spies has allegedly been defeated, ordinary citizens of many countries are having fun with "innocent" wiretapping of the phones of their friends and relatives. Anyway listening to mobile devices without the consent of both parties is prohibited by the legislation of most countries of the world.
It is immediately worth noting that it is impossible to intercept a conversation signal between mobile phones using an “antenna with a box” due to the fact that the data transmission channel between devices is quite well encrypted. The ability to intercept the channel is available only to operators mobile communications with the help of intelligence agencies. However, you can follow the person you are interested in using less complex technological solutions.
Installing spyware on someone else's phone is not difficult, as there are many applications on the Internet for listening and spying on a mobile device. They are able to secretly work on the victim’s phone and transmit information in a variety of ways: send SMS messages with your coordinates, make hidden audio and video recordings, send data to email and even take pictures with your phone's standard camera.
The risk group includes devices that are used as OS Windows Mobile and Symbian. The bug can also be installed on the iPhone, but before that it needs to be hacked.
It is quite difficult for an ordinary user to determine whether his phone is being tapped or not. But some signs of unusual behavior of the mobile device should alert you.
The main signs of wiretapping a mobile phone:
1. High battery temperature. If the battery temperature on your phone has risen and does not cool down for a long time after a conversation, you should think about why this is happening. Perhaps you just forgot to close some application that is very busy RAM device and thus uses more power than in normal mode. If you still haven't found this program, that is, the likelihood that someone planted a bug on your phone, which is hidden from your eyes in every possible way. At the moment when the temperature of the battery is kept for enough high level, your phone's battery drains quickly. However, rapid battery drain mobile device can be explained by the timing of its operation. The older he is, the less time he can work.
2. Strange phone behavior. Inadequate behavior of a mobile phone, which is expressed by an arbitrary change of backlight, turning off, running random applications and other problems, may not be caused by spyware. Perhaps such "lags" are caused by a malfunction operating system, using pirated programs or picking up virus software. In such cases, you need to pay special attention, because you don’t know which is better - spyware, which monitors your every move, or a dangerous virus, after which you will need to pretty much "sweat" to get your phone out of the world.
3. Delays when turning the phone on and off. If your phone takes longer to turn on/off, then something is wrong. It is possible that some kind of spyware is loaded during the startup of the operating system of the device. In some cases, when the machine is turned off, the backlight does not go out for a long time.
4. Extraneous noise during a conversation. Usually during listening, when a conversation takes place, the mobile phone emits an echo or some monophonic atypical noise that you did not notice before. Perhaps this is just interference caused by poor signal reception, but if the noise is heard constantly and for several days, then this is cause for concern. It is obvious that you are being watched when, during inactivity, the device begins to make extraneous sounds.
5. Constant interference. You probably sometimes noticed that such a kind of “gurgling” sound occurs near speakers and speakers during a conversation. Do not worry about this - this is normal. The thing is that during conversations and in standby mode (with some interval), the phone accesses the operator's base station. It is considered abnormal when the mobile device starts to make such sounds for a long time after you have finished the call. This can only mean one thing - the spy application has contacted another device and is starting to transmit all the surrounding sounds to it.
All phone models have a sound-to-electricity converter - a microphone. A microphone converts sound waves into electrical impulses. But for this process to occur normally, the sound must reach the microphone without hindrance.
By analogy with the human ear, where there is a sound pickup (this is what is called an ear) and a sound transducer (inner ear), the same is done in a mobile phone. There is also a sound collector (a small hole in the phone case or the sound-conducting material of the case (this is done on older Samsung models)), which directs the sound to the microphone transducer.
On the this moment 3 types of microphones are used in phones: carbon (it is on the vast majority of phones), electronic (it is on expensive phones Sony Ericsson and Nokia) and a new electronic with increased sensitivity (it is on the new Nokias above the middle class). A feature of phones with an electronic microphone is that they pick up the sound with almost the entire body of the phone, resulting in clear voice and audibility. quiet sounds much better.
The figures show different types of sound pickups in phones:
Description of types of breakdowns of microphones.
How to determine that the microphone is broken?
This can be seen from the fact that during a conversation, the other subscriber:
- Can’t hear you or can’t hear you well (or very quietly to the interlocutor, like a whisper)
- Hears every other time (everything is fine with one call, but after calling another time, he does not hear)
- Subscriber hears extraneous noise or even a hum, and the voice is barely audible or not audible at all.
In the first case you just need to replace the microphone, as this usually happens after a fall or after “bathing” the phone. Electronic microphones, when replacing, must be carefully and carefully soldered, as they are very sensitive to overheating and ingress of any liquids, so replacing an electronic microphone is more expensive. Carbon microphones are easier to replace, so the cost of replacing it is less (and the microphone too). Sometimes, when you can’t hear it at all, it’s not the microphone, then you need to look, maybe something happened to the board, or maybe something with the microcircuit and auxiliary elements. This requires time for research, which increases the repair time.
In the second case research is required to identify the real cause, as it may not be in the microphone. This is not an easy case. Therefore, the repair of such a breakdown takes for a long time. There was such a case with a new electronic microphone on Nokia, but nevertheless they figured it out and helped the owner of the phone.
In the third case, most often it occurs after a poor-quality repair, or after a fall of a repaired phone. Necessary
at Android platform you can hear yourself, phonite, crack, or any other defects appear. What to do and how to fix.
Many users face the problem when phone either tablet on Android based starts to freak out. It seems that nothing happened that could cause a malfunction, but it does not work as it should.
For example, the device has problems with the fact that during a conversation (call) any distortion or defects in the transmission / reproduction of sound appear. The reason for this may be:
1st: Software failure- i.e. the problem is crash software
2nd: hardware failure - i.e. the problem lies in the "hardware" (i.e. - replacement or restoration of spare parts of the gadget is required)
However, do not rush to get upset - in 90% of cases with problems with the operation of the data transmission and playback system and directly adjusting and adjusting incoming and outgoing calls smartphone a or android tablet is to blame software failure, which you can fix on your own.
Fixing a software bug:
Method 1. Pretty simple - go to "settings", find there « backup and reset" in which you choose full reset settings to delete all data. Be careful, using this method often turns out to be effective, but it entails deleting all photos, contacts, passwords, music, games, videos and, in general, all information stored on your smartphone e or tablet e. Therefore, first save everything you need by connecting the gadget to your computer. If this method does not suit you, or if the problem persists after it, see Method 2.
Method 2.
Based on solving problems with communication and network reception phone ov and tablet ov based Android method implementation of additional software. Utilities that control all processes inside gadgets. Today, there are quite a few of them, however, the fewer functions an application contains, the more, as a rule, it is effective. Best controls system functions, corrects, and corrects everything possible mistakes settings and synchronization is small and easy to handle, free utility for Android devices. Download app from Google Play and you can see its additional options in the description. After installing the application, it remains only to launch it. Further, from you, in principle, nothing more is required. The application will take full control of the device functions. (By the way, among other things, the gadget will start charging 20% faster, and its performance will also increase significantly, which will affect the loading and operation speed of all applications, games, and the system as a whole. On average, after scanning, the system runs on 50% faster.)
- In addition, it is worth cleaning the system with a NORMAL antivirus. Best of all, it copes with this task kaspersky antivirus , which you can download. Unlike the "multi-cleaner", the software " Kaspersky Laboratories"paid, therefore, if you do not have the opportunity to install such protection, you can skip this step ...
Method 3.
Changing the device software, or, as it is also called "re firmware ".This method, as a rule, requires certain skills and is solved by contacting the Service Center. For the independent implementation of this task, you need to contact the manufacturer's website of your device, download the utilities necessary for the firmware and the firmware itself, and then reinstall it on your gadget.
If none of the methods brought results, unfortunately, you will have to contact Service center for repair of your tablet a or smartphone a.
phoning when talking on a phone or tablet / when talking on a smartphone or tablet on the Android platform, you can hear yourself, phoning, cracking, or any other defects appear. What to do and how to fix.
You hear an echo, that is, a reflection of the signal. This interference is a consequence feedback when the caller's microphone at the other end of the "wire" picks up your voice signals from the speaker. It is not your device that is to blame, but the interlocutor's device. If the "complaint" came from your interlocutor, then you can recommend reducing the volume of your phone's speaker. If your phone is "packed" in a case, remove it or replace it with a more fitting one.
Not always the phone acts as a hindrance to conversations. Interference can be with operators cellular networks. In this case, you need to contact the subscriber service of your operator, explain the situation and wait for the results of eliminating the interference.

Why do you hear yourself when talking on the phone?
The most common cause of an unpleasant phenomenon, when you hear your own words after a short delay when talking on the phone, is being in an area of unsure reception. In other words, the signal is too weak. To combat this problem, there are special echo suppressors. An echo canceller is a device that identifies human speech coming from one end of a connection and suppresses all signals going back.
It is worth noting that a reverse echo may appear when listening to a conversation. However, this reason can be considered unlikely.
Also, the fault of the constant reflection of speech may be a software failure in the phone. In this case, it is better to contact the repair shop to diagnose the problem.
Experts identify another reason for the occurrence of an echo when talking on the phone - a "gray" (fake) or a very simple mobile phone. In this case, the solution to the problem will be to buy another high-quality model. This effect occurs when there is a mistake in the design of the mobile phone case and the manufacturer's desire to save on a special electronic element.
Among the causes of echo when talking on a mobile phone is the presence of a transceiver nearby base station your operator. To solve the problem, just change the location.
In fact, if a reflection of a conversation (echo) occurs, it will be enough just to call back or reduce the sound of the speaker and the echo during the conversation will disappear.
★★★★★★★★★★
You need to buy a phone with echo protection.
If you hear an echo, you can end the call. The echo is caused by the inability to fully connect two phones together, i.e. due to weak signal the phone starts echoing.
Mute call phone and redial, the only way solve the problem of.
Why do I hear myself when talking on the phone?
In addition to the above reasons for the occurrence of echo during a conversation on mobile phone, maybe another reason: wiretapping. No matter how strange it may sound. But not always echo during a conversation can be the cause.
This can also happen due to the subscriber being between two network coverage areas, that is, the canopy cannot determine which network the phone belongs to.
