I forgot the flip password of my Samsung phone. How to unlock? If you forget the screen lock password of your Samsung mobile phone and cannot unlock the screen, it is recommended that you try the following methods: 1. If the pattern/signature/fingerprint unlocking method is set, you can use the method of drawing pattern/signature or entering fingerprint. Set the PIN code to unlock. 1) Pattern/Signature Unlocking: When incorrect unlocking pattern/signature is entered multiple times (usually five times), the lower right corner of the screen will prompt "Backup PIN" (forgot password). Enter the previously set PIN password and click OK. That’s it. 2) Fingerprint unlocking: When the fingerprint cannot be unlocked, "Backup PIN" will be prompted at the bottom of the screen. Enter the previously set PIN password and click OK. 2. If your mobile phone supports the SamsungDive remote control function and meets the following conditions: remote control and mobile data (or WLAN) have been turned on; the mobile phone has been bound to a Samsung account, log in to the Samsung official website - Application - Find My Mobile and use a Samsung account After logging in, click "Unlock My Device". This method will directly change the previously set lock screen method to the default slide to unlock method, and then slide the phone to unlock. If the above methods are ineffective or you cannot use the "Unlock My Device" function because it does not meet the remote control function requirements, please send the machine to a Samsung service center and an after-sales engineer will help you unlock it safely.
