Regarding open pin code i tried to down load on my galaxy s3 through PC but how can i check because my phone is lock, please can you explain about this. Thanks
Hello. Welcome to Android Central.
If you have set a pin code on your S3 and forgot it, you can still unlock your own phone via your own Google / Gmail account on a pc OTA via internet / data.
Your phone needs an Internet connection, though I was able to unlock my other phone after being turned off for 3 weeks.
So log in to your Gmail account and on your inbox go to settings - devicemanager, or just go to
www.android.com/devicemanager (there are several ways) and log in with your Gmail address and password.
You should see the screen above. Try 'Locate' first and if it sees your S3 you have a data connection.
Then all you do is select LOCK on the pc. It will ask you to enter an unlock code (new). You can also put a message on the phone lock screen from there to see when it reaches your phone.
When you see that message, or without, you should be able to unlock your phone with the new code you created, after maybe a short wait.
Sorry I didn't see this earlier.
