Unhappy [Q] [HELP] SOFT Key Donīt Working

Hello,
After install the apk "Touch Control" my softkeys stopped working.
It worked for a few hours and stopped.
Soon after I did a hard reset on the phone. worked for a few minutes and then stopped.
I downloaded the stock rom google and reinstalled. Deleted everything and still the problem continues.
I did downgrade to version 4.3, installed custom rooms and still it keeps the problem.
Has anyone experienced this?
