Then an alert came on my iphone 5s about to upgrade to ios 10, i ok it, then the problem occurred i.e. crashing with a blue screen and then restarting and screen will start flickering, lines were appearing on screen and i will either get a blue screen or a white screen or other different colours.. Reasons of problems. lcd screen of iphone 5s has gone through some sort of physical damage (most of the time this is the case of display problems in iphone 5s ).; lcd screen of phone or the phone itself might have encountered any kind of water damage. software is outdated.. Some people reported the blue screen issue, after which the phone restarts itself. to some, it happened once, to others, the issue repeated several times. the nature of the problem can be both, software and hardware related. in this text, you can check out 5 ways to fix blue screen on iphone 6, and maybe one of them will do the trick..
