Hi! I have a Galaxy SII through T-Mobile. I've only had the device for approximately 6 months and love it; however, all of a sudden it is turning off at random times with random battery life left. I first noticed it about a week ago, thinking I had accidentally turned it off but now it is happening 3 or 4 times a day.
My husband purchased the Galaxy SIII with the Ice Cream Sandwich system and the salesperson told me that I might need to update my operating system to this?
