I really want a white galaxy s2 this Christmas. Loved everything about it. There is just a thing that's bugging me. Its about the burn in issue. Im planning to use this phone for 2-3 years and Im very OC when it comes to gadgets. 1. Does burn in happen in all galaxy s2 phones? 2. Can you remove it by putting a plain white background for a while? 3. Will samsung accept it for replacement when it start to appear after a few months? 4. Will I have it even if I change the way icons appear every time?
