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?
This blue screen issue can be due to a number of causes. Usually all of them are hardware issues. First, we need to know the history of this phone:
- When did this start happening?
- Was the phone previously repaired?
- Was it subject to a liquid spill of some kind? To a hard drop? In all cases, if your iPhone is still under warranty and has not been tempered with, take it to the Apple Store or an Apple Certified Service Provider/Center to try and have it repaired/replaced.
