4.2.1 Why can't I open the camera?
According to the Android system architecture, before an app opens the camera, other apps
using the camera must be closed first, for example, flashlight apps or QR code scanner apps.
Try closing these apps and then opening the camera again.

Close the apps using the GPS navigation function.

chats.

networks?

The network icon disappears when switching between networks. Voice calls will not be
affected when you switch networks.
