Phone has been activated, games downloaded, and a call made. Phone was originally charged 5 hrs, and has been charged 3-4 times with both home charger and car charger used successfully. Now, either charger will start charging (with the battery icon on screen) for a few minutes, then screen tells me battery is full & to unplug charger, but it seems there is not enough power to turn on the phone. I think it's the battery, but could it be the phone?
I have tried removing battery for 5 minutes and reinstalling but that didn't work. What are my options?
