New Iphonex screen flashing
I recently bought an iphone from Arizona USA, and almost one week into using it, it started acting weird where the screen would keep flashing for a while and the phone goes into a coma. I would leave it alone for a day and the problem goes away. I took it to the saudi local iphone repair and they told me they would not give me facetime in the new iphone. I took to bahrain and they claimed that the serial number on this phone which i got from Scottsdale AZ is not showing up on their screens where they are allowed to fix it or replace it. Now i am sitting here wondering what i am going to do next. I need help
