My Iphone 5s keeps rebooting itself every 3 minutes when sim card is in the Phone. If i take the Sim out it no longer does this why and how can i fix it? Thanks for any responses. Ps: this all started after i changed my iPhone 5S housing and display. Edit: I do not have a metal bracket on my Display Flexcable screwed in, nor do i have it at all.

Getting a blue screen on 5s is caused by mixing up the screws on the sheild that hold down the screen cables.. You have put a long screw were a short screw was suppose til go resulting in it tearing traces below the screw hole Updaten (17-01-16) Check of there’s missing capicitors near the battery connector. This can caused by changing the battery.
