There are a lot of accessories that operate under the control of the Android OS, which is additionally equipped with a special middleware - the engineering menu. With this help you can test all the sensors and modules of your mobile device, as well as adjust your gadget’s settings for a more comfortable experience. Samsung phones have Engineering Mode installed in the system. And in different models the input is shaped differently. The same functionality of this galus can also be modified. Let's take a look at how to enter the engineering menu of the Samsung Galaxy A5, Galaxy S6, J3 and other smartphones from the Galaxy line.

Where to find the engineering menu on Samsung Galaxy

The main purpose of Engineering Mode lies in the repeated testing of mobile devices at the final stage of their development. The designated middle part was initially developed for users of smartphones and tablets, but today it may happen sooner. Golovnya knows how to open the technical regime on the Galaxy.

You can access the engineering menu using an additional special combination (USSD code) that is registered on the dial panel. However, for different phone models these commands may vary:

For Samsung J7 and J1, the current combination is *#*#0011#;
for Samsung Galaxy A5, Galaxy S5, Galaxy S6, dial *#*#8255#*#* or *#*#197328640#*#*;
on Samsung Galaxy A3 the code is vikorized *#*#9646633#*#*;
for Samsung Galaxy S3 – *#*#0#*#*;
for Samsung Galaxy S7 Edge – *#*#8255#*#* or *#*#4636#*#*.

On other devices from the Galaxy line, you can quickly access service combinations *#*#4636#*#*, *#*#8255#*#* or *#*#3646633#*#*.

If you don’t have to exit the engineering menu to open the engineering menu, you can go to one of the programs developed specifically for you (EngineerMode, Mobileuncle Tools, Shortcut Master, etc.). To start the technical mode, it is enough to install and launch one of the utilities. After this, you will be automatically entered to Engineering Mode.

All programs for opening the engineering menu work only with MTK processors (MT6573, MT6577, MT6589, etc.) and with certain Exyon chips. For phones equipped with a Qualcomm CPU (for example, Samsung Galaxy A5), similar software will be limited.

Basic capabilities of the engineering menu on Samsung Galaxy

Having figured out how to get to the engineering menu on Samsung, let’s look at its main options. Full-fledged Engineering Mode for MTK chips equipped with a large number of tools, with the help of which you can create new diagnostics and fine-tune Samsung for a wide range of parameters.

However, many smartphones may have a limited version of the technical mode, which further reduces their functionality. And in mobile devices based on a Qualcomm processor, through the engineering menu you can only view information about the module’s activities and perform small tests of the main elements of the phone (display, modem, SIM cards and batteries).

On Samsung Galaxy A5 and Galaxy S6, the main sections of the engineering menu are:

Telephony;
Droneless interfaces (Connectivity);
Hardware Testing mode.

The Telephony deposit allows users to:

Connectivity section for diagnostics and setup of wireless Wi-Fi, Bluetooth and FM modules. It is not recommended to change here, otherwise it may lead to the release of the smartphone.

The most popular tab of the engineering menu is Hardware Testing. Here you can protest the efficiency of the processor, battery, speakers, camera, display and GPS module. This area allows you to perform a new diagnosis of Samsung before the time of purchase and identify possible malfunctions of the device.
