I have a vodafone smart ultra 6, I can't get past the login stage. I can't access the power options from the lock screen, i have tried holding down the power button alone and with the up/down volume button as it says on different threads. I can log in, the screen responds to touch, the login is successful. This is where the issue occurs, after logging in i am sent back to the passcode screen. I get a 2 second glance at the 4 apps on the bottom of the screen, the screen goes black and i am sent back to the passcode page. Thanks in advance for the suggestions.
