another thing that happened, while started to watch a youtube video, everything went black. i could hear the sound for a bit, but then nothing worked, and a hard reboot required. looking forward firmware update
Have you tried factory data reset?
(You must go settings--->privacy and choose factory data reset)
I resolved my problems, different from yours, in this way.
