My jelly bean update seemed to be perfect, until late last night. I was using Nova launcher and the phone kept switching between the home screen and the preview screen on its own without me touching any buttons. Over and over and over. Then it would load the media link page, which I've never pressed. Once it loads that page, it essentially freezes. You can't restart the phone in the normal fashion to clear the freeze. You have to long hold the power button for 10-15 seconds to reboot the phone. I switched to Sense, thinking maybe the problem was with Nova. Nope. Same thing on Sense. Constant crashes. Can't watch video, won't keep apps open. I was excited this morning to see a notification in the bar that an update was available for the phone. Thought maybe HTC pushed a fix overnight. I selected the notification from the pull down menu and it took me to a webpage, but then Sense crashed and took me back to the home screen before I could press whatever I needed to press for the update. Now, I can't get back to that page, and checking for updates through settings/system updates shows no updates are available. So I dunno. I guess I head to the Sprint store today and see if they can figure it out.
