My thunderbolt just shuts off by itself. Just when I've got everything working as i would like it to a new problem... My tbolt shuts off without warning. I've had a couple of random reboots but i can live with those. I cant live with thinking my phone is on when it isnt missing important calls. It has nothing to do with charge level or any other conditions i can think of. Pbone is asleep in my case and i check it and it is just off. Is this likely a problem with the phone or due to some combo of apps? Does it happen to others? I am not rooted.
