USING GO LAUNCHER but that shouldn't affect these issues. I have an EXCHANGE email account to I HAVE to have a pattern lock screen (HATE IT) Problem 1 : SOMETIMES, when I click on notifications. phone tries to go to the proper program and then it switches to pattern lock screen . This stops after phone has been on a while or when I reboot Problem 2:SOMETIMES. when an app is open and I hit the HOME button the screen flickers but it will not go to home screen. I have to hit BACK button or reboot. QUESTION 1: Is there a way (NON ROOT) to remove the pattern lock screen even though there is an exchange email account. Thanks for your help!
