Hey guys, Bought a Mi4 recently (from aliexpress) and after examining the phone a little noticed that the back cover is making a "clicking" noise and moving slightly when pressing it down. Feels like it's not fitted properly. I'm attaching a vid link: sendvid . com/yutwqalw (sry can't post links yet) Seller is avoiding me for now.. go figure Anybody got any ideas is this fixable somehow? How would I go about removing the cover safely? Thanks!
