hello guys my iphone 5s is almost 10 moths old and recently i noticed that the screen's left middle part is loose, and it's like a clickable button, actually it does make some click sound when you press it, so as it appears it might be, because of the product's quality, also i can definitely tell that battery has got worse performance than before, also power and volume buttons are loose, so there are problems, but i still got 2 month warranty, so apple said to bring this iphone to any retail store, okay but i don't live in U.S.(but the phone is bought there), and also i'm not the original owner, even don't have original box, i bought it on ebay So my question is : is it worth to send it to U.S., is there any chance that apple won't repair this phone with that issues? is there any chance that i will lose it? or something. i dont know what to do, can anyone tell me ???
