What should I do if my Android phone cannot cast the screen after disconnecting and reconnecting to the device several times?
You can try the following solutions:
1) Exit the APP and then reopen it.
2) Reboot your phone.
3) Re-download the APP.
4) Reboot the adapter: unplug all cables and wait for the white light of the adapter disappear, then connect the glasses to the adapter first, and connect the mobile phone with the adapter.
5) Check whether the connection is loose or not.
