The main reason to set up some sort of lock screen security on your smartphone is to keep strangers (or friends) from checking out your messages or private pictures. Beyond that, you don’t want anyone who dares to steal your phone to get full access to your mails, pictures or other sensitive data. But what if you’re the one who cannot access your phone? You could forget your PIN or pattern, right? Or someone pranks you by setting up a lock screen pattern and just leaves you struggling with it.
In any case, there’s quite an easy solution to this without smashing your phone against a wall (or your friend’s face). The only thing you need is to have Android Device Manager enabled on your device (before you locked yourself out of your phone).
Turn Android Phone Manager on or off
If you lose your Android device, you can use Android Device Manager to:
- find your device:Use Android Device Manager to show your device’s location.
- Ring,lock,or create a lost device:Use Android Device Manager to remotely ring or lock your device, erase everything on it, or add a phone number to the lock screen.
Unlock Android Phone
using Android Device Manager (ADM)
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 can”t recover with registered email
If you cannot recover the pattern with the registered email, then the only real option the easiest available is a Factory Reset. The only problem with a reset, is that you will lose everything on the phone unless you have a backup stored on your computer.
Power down the phone
Press either the Volume Up+Home+Power, Volume Down+Power, Home+Power
Once the phone boots up, use volume keys to navigate menu and find a Factory Reset option
Once you have located the Factory Reset option, press power key to select and allow the phone to reset itself.
Should you set up a new lock screen PIN or pattern. Make sure to write down the numbers or pattern on a piece of paper or in a text file on your computer to avoid that hassle the next time. If you run into any problems using the methods above, feel free to leave a comment.
