My Lenovo A850 phone shows no phone after matching it with car bluetooth

Hello, according to your description, it is judged that it is caused by the mismatch of the Bluetooth versions of the two, and it is recommended that you replace other Bluetooth devices that can be matched.

We apologize for the inconvenience.

This model supports the Bluetooth standard, and for the support of the car Bluetooth, the matching display does not have a mobile phone, which may be related to the compatibility of the car Bluetooth; Here it is recommended that you refer to the relevant instructions of the car Bluetooth for understanding;

It is also recommended that you try to connect other Bluetooth devices to verify whether it can be used normally; If the problem persists, it is recommended that you try a factory reset, which you can find in System Settings - Backup & Reset. Since restoring factory settings will erase the original data information, it is recommended that you make a backup first, you can use the cloud service for cloud synchronization or you can back up the data on the computer through the Le Assistant, you can visit the cloud service official**.

If the recovery is ineffective, it is recommended to go to the Lenovo repair site for inspection and maintenance in time.
