Hey all. Somehow today after talking on the phone on my tp2 they hardware keys(the 4 on the bottom) do not shut off at all now. I'm not really sure whats going on im afraid its a hardware fault or something. i've tried resetting as well as re-flashing nothing fixed it sadly

I'm wondering if anyone has any idea what could be the problem as well as if there is a program/cab file to disable the lights completely.
Thanks!
