How to enter the engineering menu on Android?

In smartphones and tablets based on the Android operating system there is a so-called engineering menu, in which additional device settings are hidden. Settings are usually intended for specialists. However, if desired, they can be used by a simple user, for example, to increase the sound on their smartphone.

How to enter the engineering menu? Let’s show an example on a smartphone based on the MTK processor (MediaTek).

Open the Phone app.

Dial the following combination – * # * # 3646633 # * # *. In the screenshot below, there is not enough symbol at the end, because when you enter the full combination, the engineering menu immediately opens. If you don’t have anything open, try clicking on the call button.

The engineering menu has opened before you.

Here you will see many different points and parameters, many of which can be changed..

It’s worth changing the parameters only if you know exactly what you are doing. If you don’t know, it’s better not to touch anything at all in the engineering menu – in order to avoid problems.

You can also download the application for MTK. In the Google Play Market, write in the search for mtk engineering mode and you will see many applications that support the engineering menu. The application works only for devices based on the MediaTek processor.

On the Samsung Galaxy, the engineering menu is opened by typing * # 0011 #. Before you see this:

To use, press the “Menu” button on your smartphone and select Back.
