Where to find the engineering menu on Samsung Galaxy
The main purpose of Engineering Mode is to full testing mobile devices at the final stage of their production. This environment was originally developed for debuggers on smartphones and tablets, but today anyone can use it. The main thing is to know how to open technical mode on Galax.
You can enter the engineering menu using a special combination (USSD code), which is written in the dial panel. However, these commands may differ in different phone models:
- in Samsung J7 and J1 the actual combination is *#*#0011#;
- for Samsung Galaxy A5, Galaxy S5, Galaxy S6, the dial *#*#8255#*#* or *#*#197328640#*#* is suitable;
- 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 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 developed specifically for this purpose (EngineerMode, Mobileuncle Tools, Shortcut Master, etc.). To start the technical mode, just install and run one of the utilities. After this, you will automatically enter Engineering Mode.
All applications for opening the engineering menu only work with MTK processors (MT6573, MT6577, MT6589, etc.) and some Exyon chips. For phones equipped with a Qualcomm CPU (for example, Samsung Galaxy A5), such software will be useless.

And in mobile devices based on a Qualcomm processor, through the engineering menu you can only view information about some modules and perform small tests of the main elements of the phone (display, modem, SIM cards and battery).
On the Samsung Galaxy A5 and Galaxy S6, the main sections of the engineering menu are:
- Telephony;
- Wireless interfaces (Connectivity);
- Testing mode (Hardware Testing).
In the Telephony tab, the user has the opportunity to:
The Connectivity section is intended for diagnosing and configuring Wi-Fi, Bluetooth and FM wireless modules. It is not recommended to change anything here, as this may lead to failure of the smartphone. 
The most popular tab in the engineering menu is Hardware Testing. This is where you can test the performance of the processor, battery, speakers, camera, display and GPS module. This area allows you to perform a complete diagnosis of Samsung during its purchase and identify possible malfunction products. 
Manufacturers of Android smartphones implement and use the engineering menu to test devices. It contains all kinds of tests and device settings that are not available to ordinary users. However, today, knowing the USSD command or downloading the application from PlayMarket, anyone can go to the engineering menu.
