What should I do if the Samsung s 4 signature unlock suddenly fails to open?
If the Samsung mobile phone forgets the screen lock password and meets the following conditions, it is recommended that:

1. Remote control and mobile data (or WLAN) has been started.

2. The mobile phone has been bound with a Samsung account. Log in to Samsung official website-Apply-Find my mobile phone. After logging in with a Samsung account, click Unlock My Device. After this operation, the previously set screen locking mode will directly become the default sliding unlocking mode, and then the mobile phone will be unlocked by sliding.

3. If it is invalid, you forget to back up your PIN password or it does not meet the above requirements, please send the machine to Samsung Service Center, and the after-sales engineer will help you unlock it safely.
