Discovered that the lock button on the side of the phone and the red end call button does not work...by themshelves! I have to push the home buttom and either one of the non-functioning buttons for it to work. It's both a relief and pain to have figured this out. For the longest time, I thought the battery was horrid because when I would push the unlock button, the phone would not recognize it so the screen remains black making me think it off, out of battery. But then I noticed recently that the phone comes on when I hit the home button. This is such a let down, you are never happy when your purchase breaks. Fortunitely I have the replacement insurance if it need be used. I was wondering if this is a known problem and can be fixed by me or if the phone need to be sent in for a replacement. Assistance is appreciated. Thanks!
