Hello...I have a Samsung Galaxy S2 Epic through Sprint. I will be texting or on another app and the app will close and will go back to the home screen or the task manager. Sometimes when I am not even touching the phone it'll go to the task manager and then back to the home screen. My gmail account is also not staying synced to my phone and I have to refresh everytime a check my emails and don't get a notification on my phone anymore. Can someone help me?? Thanks!!!
