So I have a problem with signing on to my device,I recently updated to 4.0.3 (ice cream sandwich) and tired to setup a pattern lock witch i forgot and now I need to login with my Google account. Every time I type my email and password an pop-up show up with ''checking...'' and as soon it's start my screen goes black and i need to type it again. I've tried to do everything i could but it just won't let me pass the email window.I can receive calls and texts. Any help comment would be greatly apprciated. Thank You.
