Hello, I have A LG Thrill that is 5 months old. 1 week ago I received a phone call and couldn't answer it because the phone locked up. I had to remove the battery to end the call. When I put the battery back in the phone,the phone wouldn't power back up. Took 3 times of reinstalling the battery for the phone to power up. My phone locks up a few times a day and sometimes shuts itself off. Never does the power right back up after reinstalling the battery,sometimes the phone will lock up on the Rethink Possible while turning on. I've also noticed that the battery drains down without being used. Any help at all would mostly be appreciated.
