(These codes seem to be standard for Alcatel phones. Interestingly, they work here, too.)
This is similar to the BBVE and provides various tests for all phone components. To open it, open your phone dialer and type this:
* # 2
MNO # (“AUTO”)
To test single components or get traceability information (PRD number, manufacturing date, etc.), tap “MANU”. The buttons “AUTO1” and “AUTO2” run several tests automatically. To exit the test mode, tap “MANU” and find the “Exit” option at the end of the list.
This mode has a few settings (black font on black background – hold your finger above where the text should be for the background to become grey, making the text visible).
* # * # 2
DEF # * # * (“ANDROID”)
