It has only been less than three weeks, but it already stuck on me twice while I was making a regular call, and a Skype call. The screen went blank, and there was nothing I could do. Pressing the home button twice took me out of the blank screen every now and then, but it showed me I was still on the call. The MayDay did not work here either. I am out of town, and there is no way I can return this as I do not have the box on me.
