after the update, today my phone rebooted after the sound stopped working on one of my apps, so I switched to another app and it rebooted. It stuck at the boot logo so I had to pull the battery. Waited a few seconds then i put it in. The power button was not responding until like the fifth try of turning it on. Then when it did power on the screen was redicuolously bright, yes I had it at 100% but it was like almost blinding bright but in a good way, as I had thought this screen wasnt very bright even at 100%. Has anybody else experienced something like this?
