What if the Bluetooth infrared of Samsung mobile phone can't be opened?

If your phone can't turn on Bluetooth, I suggest you: 1. Restart your phone and try again. 2. Uninstall the third-party software. 3. Back up important data (contacts, photos, memos, etc.). ) and restore the factory settings. 4. If there is an update, please try to update the system software. If the problem still exists, it is recommended that you bring the purchase invoice and the three-guarantee certificate to the Samsung service center for testing.
