I have a Samsung galaxy s3 and i locked my phone with a numerical pin, but i dont remember it. is there anything i can do?
Sign into your Google account from any other Android phone or a PC. Then use the Android Device Manager along with your password to unlock your phone. Otherwise, you'll have to do a factory data reset and all your data will be lost unless you've backed it up.
I have heard you can go to Android Device Manager in your Google Account online and unlock it from there.
