Everything was fine until today. I noticed I hadn't received a call I was expecting so I tried to open the phone but it had shut down(I guess) tried to turn it on but all I could see was a battery showing 75%. I removed the battery and it rebooted and all was good for an hour and it shut down again. I removed the battery, again, and it restarted so I will see how long it lasts....I will be returning it if it happens again! Any suggestions on whether to try another Bionic or ?suggestion?
