Part 2: Fix Android Enter PIN to Unlock Not Working in 7 Ways

> Way 1: Inspect the PIN

Confirm you're entering the correct numbers or letters. If you recently changed your PIN, make sure you're using the new one. Also, test your PIN on another device, like a computer or tablet, to ensure it's correct.

> Way 2: Restart your Android phone

• Press and hold the power button until "Power Off" or "Restart" appears.
• Select "Restart" and wait for your phone to reboot, then try your PIN again.

> Way 3: Wipe the cache partition

To clear the cache partition and potentially fix the PIN issue:

• Power Off your Android phone.
• Hold "Volume Up + Power" until the recovery menu appears.
• Press "Volume Down" to navigate and "Power" to select.
• Select "wipe cache partition".



• Choose "Yes" to clear the cache, then select "reboot system now". After restarting, try your PIN again. This won't delete personal data. (What if your phone won't power on?)

> Way 4: Unlock Android via Smart Lock

Smart Lock can automatically unlock your Android in trusted locations or when connected to trusted devices, so you don't always need your PIN. To use it:

• If you've set up Smart Lock, take your phone to a designated trusted place (like home Wi-Fi) or connect to a trusted Bluetooth device (like a smartwatch).



• Your phone should automatically unlock if it's in a trusted environment, even if you've forgotten your PIN.

> Way 5: Reset your device with Find My Device

Before proceeding, you must be signed into your Google account on the locked device. Then, Google Find My Device and Location must be turned on in your phone's settings beforehand. To use this tool:

• On a computer or another device, visit Find My Device and sign in with your Google account linked to your locked phone.
• Choose the locked device from the list.
• Select the "Erase Device" option. This will factory reset your phone, deleting all data, including the PIN.



• After the factory data reset, set up your device from scratch and create a new PIN.

NOTE: If erasing the device is not an option, and you cannot remember your PIN, consider trying:

• Wait for a period before attempting to enter the PIN again, as repeated incorrect attempts might temporarily lock you out.
• Use any security questions or biometric options (if available) that you set up previously.
• Seek help from the device manufacturer's support team for additional recovery options.

> Way 6: Use SmartThings Find (Samsung only)

If you have SmartThings Find set up on your Samsung phone beforehand, try to unlock your device using SmartThings Finde. To use this feature to fix a phone that does not accept the correct PIN:

• On another device, visit SmartThings Find and sign in with your Samsung account.
• Locate your phone in the list of registered Samsung devices.
• Choose the "Unlock" option, and follow the prompts to confirm your Samsung account credentials.



• This should remotely unlock your phone, bypassing the PIN.
• Once unlocked, go to your phone's "Settings > Lock Screen" to set a new PIN.

> Way 7: Utilize ADB Tool

This method works on certain devices and requires USB debugging enabled and ADB installed on the computer.

• Connect your Android device to a computer with a USB cable.
• Ensure ADB is installed on your computer.
• Open the command prompt (Windows) or terminal (Mac/Linux), then navigate to the ADB installation directory.
• Type the following command and press Enter: adb shell rm /data/system/gesture.key



• Restart your phone. The lock screen should be bypassed, allowing you to set a new PIN.

* ADB cannot retrieve or display your current PIN due to Android's security measures. However, it may help you remove the lock screen PIN file temporarily.
