IPhone 4S Back Panel Loose (Need Advise)

Question

Hello, everyone.
I would really appreciate if you will read whole message.
I’m Max. I live in Ukraine and as Apple doesn’t officially sell it’s phones here people frequently buy expansive imported iPhones (European, US or UK ones usually). And so I did. Obviously those are not covered by any of Apple’s policies or official warranty, if covered by anything at all. I mean here. So I ended up with new iPhone 4S from Italy with three (3) month of it-is-not-an-issue-pay-or-get-lost warranty.
Now, the problem is that phone’s back panel making sounds after a month of really intensive use (gaming, etc.): it clicks when pressed sometimes and it kinda knocks if tapped quite a bit. All the issues are within the area where battery resides. I don’t know what to think. It might be glue lost adhesive or something. I don’t want it to get worse.
At service point we tried tightening screws and resealing back, but accomplished nothing. Guy there told me that he can’t replace the panel because there are no visual defects or a single flaw he can consider as warranty case. Even part itself looked perfect to him. Of course device replacement simply isn’t an option too. I don’t feel like spending money myself either for now.
And what is interesting is that he shown me four or five iPhones (4s and 4Ss) currently in his service due to completely different reasons and all of them had gaps and loosen backs of different sorts, including really horrific ones. He said it’s quite a normal («normal» means most iPhones, in his opinion, have that flaw). I understand that all of them were used by different people under different circumstances.
So the question is how many iPhones (if any) experience such an issues? Maybe yours? How old phone was when it started? How many of your friends phones doing it? Please, do not answer if you’re not sure.
Note: it’s a real iPhone that I own, not a copy of any sort. Also, I’m acknowledged about camera lens rattling. It’s definitely not the case.
