Seems like you didn't align it perfectly. Like I said, it has to be PERFECTLY aligned. YOu can just deattach and reattach it. It worked for me after 2 times it's a PERFECT fit (as you can see on my pictures) Edit: I bought it from http://www.ebay.com/itm/381352415726 (seems like HTC One M7 is out of stock from that seller...) But let me take a couple more (better) pictures for you to show what I have right now on my Jolla, maybe you've also got the same as I have?
