Why doesn't Huawei mobile phone compass display the sea dial?

The device opens the compass application, but does not display the air pressure value and altitude.

The cause of the problem:

Only devices that support barometers can display barometric values and altitude. If the barometer is not supported or its function is damaged, the barometric value and altitude will not be displayed.

Solution:

Please check whether the equipment supports barometer in the product parameter table first.

If the device does not support barometer, the barometric value and altitude cannot be displayed.

If the device supports barometer, but still can't display the barometer value and altitude, please back up the data in advance (third-party applications such as QQ and WeChat need to be backed up separately), and bring the purchase voucher to the nearby Huawei customer service center for testing.
