I have the same problem. I went back to the Apple store to change my iPhone 6s but I keep having this problem. I only have this on the facebook app though, so I think it might be a facebook issue of the app.
Hey, did the issue get resolved as yet? I just got a new iPhone 6s Plus but the vertical pink lines keep on appearing on the Facebook app. I had the same issue when I got it a month ago but I go that set changed but the problem seems to persist. Help!

I'm a student and I used most of my savings to buy the new iPhone 6s.. When you pay that much money, believe me, I'm worrying about it constantly when this occurs. It happens all the time, and strange that it happens only with facebook[/QUOTEi
I know what you mean! The only reason why I'm here right now instead of enjoying my phone is cause I'm a student and can't afford such phones again and again atm
