So I have been using my Z3 for about a month now, I recently noticed that my phone doesn't lay flat on the ground, it wobbles a little, then it starts to worry me, under close inspection, the back panel between the power button and the microSD card slot was elevated up, I am really concerned about it, is it because the overheating of the phone? The adhesive is melted by the overheating of the phone? I am scared that the phone will loss its waterproof ability…
Sorry @Curnow1 now i understand what you mean......its like a possible cover....maybe a thin glass protector, well spotted my friend :smileysmileythumbsup:
Lets wait to see if Pz3004 answers re if he has fitted a cover or glass protector.....looking at various pictures of the back of the Z3 this 'cut out' is not apparent......unless they changed it from the first models, did some have glass backs then they were changed to plastic 
I really couldnt say......have read some people on here say yes & also some people say no, its not a gamble i would like to take to be perfectly honest

In that case i would definetly say it is the thin glass protector that has came loose....may have been fitted too tight against a top or bottom edge..phone heats a bit thru use, glass expands & the first place it would start to 'pop' up is the area described......what do you think?
