Their maybe is a problem in your iphone.I don't have this problem but something is wrong.I say go to your local Apple store and get it check
i m putting up this thread from canada.
i bought my phone yesterday, and when i press the sleep mode button on top, the screen goes to sleep but right before it does, a black line appears across the screen and flickers, like an old TV turning off.
does anyone else have this problem ?is this normal?
also, there seems to be a small dust particle underneath the glass of the screen,i've read many other threads regarding dusts trapped inside the screen, do apple give you a new one for this reason?- the phone has a loose hole somewhere obviously, letting dust in.
also, regarding excahnges for new ones and such, does the retailer store do it?or do you have to directly do it with apple?
thanks in advance
