My screen will not turn off for any reason. I set it to the 15 second timer and waited for about 5 minute. nothing Pressing the power button does not make it turn off, but holding it makes the standard Power off/Airplane/Restart menu appear, so it isn't just broken. If I download an app to turn the screen off, it turns off for about 1/4 a second and then turns back on. I've tried wakelock detector, but it doesn't give me any apps keeping the screen on. I've restarted it a few times, did a hard reset, and I even did a factory reset. No idea what's causing this.
