How to enter the engineering menu on Samsung. How to enter the engineering menu on Android? Samsung galaxy s6 engineering codes
Many devices running the Android OS are additionally equipped with a special environment - the engineering menu. With its help, the user has the opportunity to test all the sensors and modules of the mobile device, as well as adjust certain parameters of the gadget for himself for its more comfortable use. In Samsung phones, Engineering Mode is hidden in the system by default. And in different models, the entrance to it is performed differently. Yes, and the functionality of this area may also differ. Let's see how to get into engineering menu on Samsung Galaxy A5, Galaxy S6, J3 and other Galaxy smartphones.
Where to find the engineering menu on Samsung Galaxy
The main purpose of Engineering Mode is to fully test mobile devices at the final stage of their production. The specified environment was originally developed for debuggers of smartphones and tablets, but today anyone can use it. The main thing is to know how to open the technical mode on Galax.
You can enter the engineering menu using a special combination (USSD code), which is written in the dial pad. At the same time, in different phone models, these commands may differ:
- in Samsung J7 and J1, the combination *#*#0011# is relevant;
- for Samsung Galaxy A5, Galaxy S5, Galaxy S6, *#*#8255#*#* or *#*#197328640#*#*;
- on Samsung Galaxy A3 the code is *#*#9646633#*#*;
- for Samsung Galaxy S3 – *#*#0#*#*;
- in Samsung Galaxy S7 Edge - *#*#8255#*#* or *#*#4636#*#*.
On other devices from the Galaxy line, you can use the service combinations *#*#4636#*#*, *#*#8255#*#* or *#*#3646633#*#*.
If you can’t open the engineering menu using the above commands, you can resort to one of the programs designed specifically for this purpose (EngineerMode, Mobileuncle Tools, Shortcut Master, etc.). To start the technical mode, just install and run one of the utilities. After that will happen automatic login in engineering mode.
All applications for opening the engineering menu work only with MTK processors (MT6573, MT6577, MT6589, etc.) and with some Exyon chips. For phones equipped with a Qualcomm CPU (for example, Samsung Galaxy A5), such software will be useless.
The main features of the engineering menu on the Samsung Galaxy
Having figured out how to enter the engineering menu on Samsung, let's look at its main features. A complete Engineering Mode for MTK chips is equipped with big amount tools that can be used to complete diagnostics and fine-tuning Samsung in many ways.

Battery: disable unused frequencies
Smartphones quickly consume battery life for running applications, maintaining cellular communication and network connections. Using the engineering menu, you can increase the battery life.
Modern devices scan several GSM frequencies - 900/1800 MHz and 850/1900 MHz. In Russia, a pair of 900/1800 MHz operates, which means that there is no need to scan the network at other frequencies. The radio signal for the second pair can be turned off, which will significantly save the charge level.
In Engineer Mode, open the Band Mode item. Disable unused frequencies by unchecking the corresponding items - PCS1900 and GSM850. If the device supports two SIM cards, open SIM1 and SIM2 in turn and follow the steps in each. Press the SET button to save the settings.
If your smartphone and SIM card work in 3G networks, disable networks that are not used in Russia: WCDMA-PCS 1900, WCDMA-800, WCDMA-CLR-850. Press the SET button again.
You can enable scanning of disabled networks by returning to the same menu and checking the boxes.
