Hi All, I just switched over and am somewhat overwhlemed with all the control that I have on my galaxy s2. I have a few questions and points to make. 1 - My phone is not responsive during charge. 2 - I downloaded juice defender and I am not sure if I need to do anything now? 3 - When I go into task manager am I supposed to clear the memory as well as kill the open apps. 4 - I noticed today that some contacts are duplicates and was not sure what that meant. I use microsft exchange server. Thanks.
