I've had problems with the SGS2 camera since I got the phone and I can't seem to find a solution to the problem. It is still within the exchange window so I plan on replacing it with a new SGS2. Couple questions....I assume I should do a factory reset before exchanging? Don't need any personal info left on the phone, right? Second...will I have to repurchase apps that I have paid for? I would think they are somehow linked with your account... Thanks for any info.
