Many people think there is universal master unlock codes for any Android phone. But this is not true. The best way to unlock your android phone passwords you need to do a factory reset. On any Android phone, this process usually looks similar. To do a factory reset on an Android phone you need to do:

• Your phone must be OFF. If you can’t turn off your phone (because you need to enter a password or pin) just take off the battery if you can’t do it so just wait until the battery drain to 0%. Only after it:
• Press the Power button + Vol Up or Vol Down button together for a few seconds
• On some Android phones you will need to press 3buttons: Power + Vol Up or Down + Ok button (usually this button is on the center at the bottom of the phone. On most phones this btn is a sensor)
• If the combination works on your phone you will see the Reset Menu.
• Then choose to wipe data/factory reset by using Vol Up Vol Down and Power btn to confirm.

These steps will reset your Android phone to the factory setting and all your password and personal info will reset. So I recommendable to make back up or using the synchronization function to restore all your info after resetting.
