ROG Phone 5 ROG Kunai 3 right controller not working when attached to bumper

Please tell us some basic information before asking for help:

  1. Model Name: ROG PHONE 5 / ROG KUNAI 3
  2. Firmware Version: I cannot even check the firmware version nor update it
  3. Rooted or not:not
  4. Frequency of Occurrence:Always
  5. APP Name & APP Version (If your issue relates to the app):Home screen, Any games

In addition to information above, please also provide as much details as you can, e.g., using scenario, what troubleshooting you've already done, screenshot, etc.


The right controller does not work when attached to the bumper. The phone will display this message: "Analog audio accessory detected The attached device is not compatible. Please contact the accessory manufacturer for further support. It used to work for the first few months. It stopped working since around July.

However, the controller does work fine if I connect it to the phone using a USB C cable. Both sides of the controller will work.

How do I solve this issue? I cannot seem to trigger a firmware update as well.
