Setting up a screen passcode or pattern is a standard practice to safeguard your data and privacy on your Android device. But what happens when you forget it? You will be locked out of your phone, unable to access its functions. You may wonder if there is a master code to unlock any phone. Let's explore whether such a code exists and whether it effectively restores access to your device.

Does the Master Code to Unlock Any Phone Exist

The master code to unlock Android phone is a universal unlock PIN that can help a user bypass any screen lock without a factory reset. The concept sounds ideal. But does such a secret code to unlock Android phone password truly exist?

The answer is both yes and no. There are two master PIN codes known to work on certain older Android models: *#*#7780#*#* and *2767*3588#. *#*#7780#*#* is widely considered to be the master code to unlock any button phone

However, these codes have limited effectiveness and might not be compatible with newer Android devices. If you own a recent Android model, chances are there is no master unlock code available to remove the screen lock. Consider this: if a master code existed, anyone could learn it and potentially unlock any stolen Android phone. If you are looking for a 100% workable solution to unlock your Android, download the EaseUS unlocker software.
