Possible problem with display.

Dear Sirs,

Specifically iPhone6 I have purchased over the mt:s network (your official reseller in Serbia), there is no problem in using the device but it happens for example when the phone is long on a warm place (pocket for example) to be in the top right corner when you press on the screen that can be heard as if something falls off, as that there is leeway between the glass. The only thing that is annoying is that sound otherwise the phone works without any problems even then, touch the screen have no difficulties at work. Only this is a question for you that you had such a case, and whether therefore need to activate the guarantee?

Best regards,

Strahinja.
