Locked out of a Samsung Galaxy S2 My phone was stolen recently, and I'm trying to use my wife's old S2 as a temporary replacement.
She had a password screenlock, and she can't remember what it was. When I put in my new SIM, the screenlock is still there. Is there a way to get around it?
This might work:


From your computer, open Play Store:Android Device Manager.
Log in from the same Google ID which you used to set up your phone.
Click on Install and select the locked phone. In few minutes, your Android Device Manager will be installed on your phone.
Now open Android Device Manager with your computer.
There will be a button named Lock. Click that and set up a custom password and finish by clicking Lock.
The screen lock will be replaced by the custom password you just set up.
Voila! Use the password and unlock your phone!
