Ok, I'm not 100% sure if this is actually a problem but I'm worried it might get worst. The problem occurs when I turn the S2 off and the lens is supposed to retract. Instead of retracting instantly like it usually does, it starts retracting, stops for about 2 seconds (you can barely hear some kind of ticking sound) and finally it keeps retracting. At first it barely did 1 out 20 times I turned it off, but now it's the opposite! 1 out of 20 times it turns off normally, and today I got the same problem when turning it on! It hesitated when powering up :S Is this normal? Do you S2 (or S1) owners have the same problem? Everything else works great!
