How to bypass Android’s lock screen pattern, PIN or password

As already mentioned, the following method only applies to devices that have Android Device Manager enabled.

On a computer or other mobile phone, visit: google.com/android/devicemanager
Sign in using your Google login details that you also used on your locked phone.
In the ADM interface, select the device you need to unlock (if it isn’t already selected).
Select ‘Lock’
In the appearing window, enter a temporary password. You don’t have to enter a recovery message. Now click ‘Lock’ again.
If it was successful, you should see a confirmation below the box with the buttons Ring, Lock and Erase.
On your phone you should now see a password field in which you should enter the temporary password. This should unlock your phone.
Now, before you go on with your life, go to your phone’s lock screen settings and disable the temporary password.
That’s it!

If you haven’t updated your firmware to Android Lollipop (5.0), then there’s a faster way to unlock a lock screen pattern.

Enter a wrong lock screen pattern five times (shouldn’t be hard if you don’t remember the correct one)
Select ‘Forgot Pattern’
Now you should be able to enter a backup PIN or your Google account login.
Enter either your backup PIN or your Google login.
Your phone should now be unlocked.

This is an easy way to unlock your Samsung device if you created a Samsung account and registered it beforehand.

Go to Samsung Find My Mobile.
Sign in using your Samsung login details.
In the Find My Mobile account interface you should see your registered phone on the left hand side. This tells you that you’re phone is registered to that account.
On the left sidebar, select ‘Unlock my screen’.
Now select ‘Unlock’ and wait for a few seconds for the process to finish.
You should get a notification window telling you that your screen is unlocked.
That’s it. Your phone should be unlocked.
