iPhone 5s randomly restarts with blue screen
iphone 5s, 64GB version, was working fine (iOS 8.2 for almost a month) but recently started to restart at random times.
Did firmware upgrade (via DFU mode) and setup as new phone - it still restarts. When it restarts blue screen appears for a while and this gets logged, below.
iOS 8.3 did not help - still restarts.
Is this some known hardware iphone bug?
Is this a good question?
