So in my eyes this is a non-issue as I have seen it on many iPhone 6's. If you apply pressure near the edge of the screen on the left hand side above the volume rockers, you will be able to see the little plastic seal and screen are indeed loose and are being pushed into the screen. I've seen this on every iPhone6 I've come across so far. Some have it worse than others. Some make clicking sounds if you listen closely. If you run your fingers over the edge of each side of the screen, there should be a notable difference and on the loose side your fingers should "snag" on the edges. I just found this interesting that it only happens on one side and can sometimes be really bad if it makes a clicking sound like one of my previous iPhone 6's. Let me know if you to have this on your iPhone please!
