1. Remote control and mobile data (or WLAN) has been started.
2. The mobile phone has been bound with a Samsung account, so you can log in to the Samsung official website-Remote Control webpage. After logging in with a Samsung account, there is a screen unlock option, which can be unlocked through this function. After this operation, the previously set screen lock mode will directly become the default sliding unlock mode.
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.
