These Android Secret codes are mostly universal, and should work on Android devices, no matter the manufacturer. There might still be carrier restrictions on certain codes though, so they’re not all guaranteed to work.During my time in analysing android codes i found different ways to diagnose and test the hardware and software on Android. I found various codes that would get you in and out of hidden menus within Android. If you guys promise not to share any of this info with anyone else I’ll tell you everything that I know.
