Actaeon

I literally just went through a bout with this.. Mine started nearly a year ago, but I was always able to get it to stop with a knock on my knee or a slight twist as others have mentioned. Finally, one day it happened and would not stop. I'm (literally) a few weeks away from completing my (very patient for me) two year plan of waiting for the 7, and now have a 6 plus that doesn't work. I went back to my 5 for about a week and was so frustrated by the that, that I spent like 2 days straight messing with it. Finally (after hours and hours) I was able to place two strategically located pieces of rubber (one underneath and one on top) on the logic board, which serves to slightly twist it inside the case when pressure is applied from the screws and screen. It went from completely grey bar and unresponsive to 100% working for about a week now (typing this reply with it). Looks like I'm going to make it, but I'm really fairly disappointed with the durability of the 6 Plus in general... I have like 4 iPhone 5s kicking around that survived all of my pre-teen kids.  That's what we get for being new model year adopters! . PS - I wouldn't recommend anyone trying this method if it's really bad like mine - it literally took hours and hours because all you can do put it all back together, close the screen, hope it works, and if not, break the ENTIRE phone back down and try again.. This results in one try every twenty minutes or so
