i have the samsung galaxy s2, Today an android guy appeared, just after i unlocked my phone on my break, at the top of the screen, it's telling me upload your sexiest pictures. Well i can't clear it. I've taken out the battery- the sim card, and restarted, nothing works. Then when i was at a fitness class, i couldn't get any service for about 10 minutes close to that building until left 10 min out. I had bars, but it said i could only make emergency calls. Now my bills been paid, it comes directly out of my account, what's wrong with my phone and how do i get rid of the green guy?
