Firstly Merry Christmas to Everyone! I woke up Christmas morning to find faint vertical lines on my iPhone 5S screen, which only show up in a really dark room and only when certain colours are on screen. I ordered this phone on day of release so is a couple months old now but has never been dropped and has always been in my slim armour case. I tried restarting the phone and when it restarts a few bright pixels are displayed on the screen until the apple logo appears, I guess you would call them screen artefacts. So my questions are, would you say this is a hardware fault? Is it worth even trying a restore? Is this a common or known problem? I have attached an image which shows the lines, sorry about the quality it was taken in the dark using my iPad. Thanks in Advance!
