It all started when I made the fatal mistake of clicking on the "footprints" application. Now my phone's screen keeps going black every few seconds. It takes 3 presses of the power button to get the screen back on but then you'll never know how long it'll end up staying on. I've tried to use my app killer but that doesn't seem to fix it either. It's not the brightness settings because I haven't recently changed those. This is so annoying and is making my phone basically useless.
