Good afternoon guys, I am an owner of an iphone 5 on ios 7.1.1 and since a few weeks, my screen is flickering for a few minutes and then later stoo again. It all started when i had 1 months ago ios 6 on my phone, then i updated it and it alread happened another time on ios7 and yesterdas 2 times. I don't really know the reason for this, but do u think if i send it to my oparetor , that apple will switch my phone? Otherwise i will have to pay 50bucks to get the phone back, without that they didn't "repair" it. What do u think? Did sby faced on time the same problem?
