I have had my iphone 5s for only about one and a half maybe 2 months. I bought it from wal mart under straight talk. After updating my phone last night I woke up this morning and added some minutes to it and the screen turned blue. For the past few weeks occasionally the screen would flash blue and the the phone would reboot but would be fine but now the every time it tries to boot it turns blue and gets stuck in a loop.
