What's wrong with Samsung Note3 device encryption?

According to your description, I suggest you: 1. Turn the machine on and off again.

2. Settings-General-Security-Clear Certificate

3. If the lock screen setting is grayed out except the password, and the words "stored by the administrator, encryption policy or certificate" are prompted, it is because the device encryption or external SD card encryption function is set in the mobile phone. If you need to change the screen lock mode, you need to decrypt the device or decrypt the external SD card first.

Operation:

1, cancel device encryption. Mode: Settings-Security-Decryption Device-Click Decryption Device-Enter Screen Lock Password-Click Decryption Device at the bottom of the screen again-Wait for completion.

Note: When canceling device encryption, the mobile phone needs to be connected with a charger.

Samsung official website has produced an illustrated function tutorial for the decryption device function. Please refer to:

2. If you can't operate, it is recommended that you back up your mobile phone data (phone book, SMS, multimedia files, etc.). ) and restore factory settings (enter phone settings-reset-restore factory settings).

If the problem still exists, it is recommended to send the mobile phone to the nearest Samsung service center for testing and further processing.

It is recommended that you apply for "booking to the store" in Samsung official website and enjoy priority maintenance service:/pre-order.

After the appointment is successful, please bring your machine, invoice and warranty card to the service center you reserved on time.
