If you forget the screen lock password of your Samsung S4 phone, we recommend that you refer to the following:

1. If the pattern/signature unlocking method is set, you can use the method of drawing the unlock pattern/signature. Set the PIN code to unlock. Operation:

1). Enter five incorrect unlock patterns, and the prompt message "Please try again in 30 seconds" will be displayed on the screen. Click "OK". Click "Backup PIN" (forgot password) in the lower right corner of the screen, enter the PIN password you set previously, and click OK.

2). If it is the signature unlocking method, after entering five incorrect signatures, a prompt to enter the PIN code will appear on the screen. Enter the PIN password you set before and click OK.

Tip: The PIN code prompted when unlocking is the backup password you set when setting pattern lock, etc.

If it is invalid, the backup PIN password is forgotten, or it does not meet the above requirements, please send the machine to a Samsung service center, and an after-sales engineer will help you unlock it safely.
