So after I updated my iPhone 6 to iOS 10 everything has been pretty good so far, but I have noticed that when you hard reset the iPhone (home+sleep buttons) the screen now turns to either a grey or yellow-like colour and has an odd scan line-like pattern on it when the screen goes off, instead of just black as it used to. Does anyone else get this issue? Anyone know what might cause it? I updated my phone via OTA instead of iTunes. I've seen it happen to someone else's iPhone 6 at work. This person on the Apple forums has the same issue, but all they got as a reply was to visit the Genius Bar. https://discussions.apple.com/thread/7675926 It doesn't effect the use of the phone as it will restart as normal. I'm just interested why it's happening after iOS 10.
