Service or engineering codes are present in any device running on the Android OS. Originally, their main purpose is to test devices before sale or during production. They are not widely known to the general public, so unless you are an engineer or a tech enthusiast, you probably haven’t come across them.
Service or engineering codes are alphanumeric sequences that allow access to hidden menus and diagnostic tests for any user. Most of the codes that AdmiGram.com will talk about are generic and can be used on Android devices from various manufacturers.

Service (engineering) codes for Android phones and tablets
Be cautious!
Since some of these codes can make changes to your device’s configuration, which can lead to resetting settings and losing some device functionality, do not enter parameters that you don’t fully understand.
Once you enter the code, the required menu or function should automatically launch. If this doesn’t happen, it means either you made a mistake while entering the combination or your smartphone doesn’t support this code.
To use the codes on your Android phone, simply enter the desired code in the dialing field.
