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.

Going back to try the update method with the controllers attached to the bumper.
If you set the controller to bt the update will not be triggered.
You have to set it to usb.
Update Triggered.

Seems like other people encountered the same problem.
Seems like they went through hell to get it resolved.

I wanted to just make a gamble and buy a new Kunai 3. But it is out of stock everywhere, including the official store in Singapore. What should I do when I cannot even buy a replacement set?

If the problem is the update, how do you reset the Kunai 3 to factory settings?
Would that work?

New way to trigger firmware update.

Attached controller to bumper. Go to any game. Open Game Genie. Press Key mapping. It will sometime trigger a firmware update.
