My phone will suddenly switch to downloading an app in the middle of playing a game or reading email. It also turns off automatically and the screen tries to lock like right now even though the setting is for five minutes ofter screen locks and the screen is not locked. I have even had it reset at the store and this made it better but it did not fix things. I was told to keep roaming on keep the GPS off as my battery only lasts 6 hours and I got this phone new in November. Can anyone help?
