Hello all, I am having an issue with missing calls. When someone calls my phone it will ring like normal on their end, but it will not ring at all on my phone. The only way I know that somone has called is if they leave a voicemail or text message me. This only happens if my phone has been sitting with the screen off for awhile. If I have been playing a game or anything then turn the screen off and someone calls its fine, it almost seems like it goes into a hibernation mode and doesn't wake up. I know its not an issue with data interfering with the cell phone, I have the data always turned off. This happens to both my droid 2's, any ideas? Is it a carrier issue? Thanks.
