In addition to the information above, please also provide as much details as you can, e.g., using scenario, what troubleshooting you've already done, screenshot, etc.
I already read the same cases here in ZenTalk and tried updating the firmware by attaching it to the kunai charger and connecting it to the phone via USB C. The firmware update prompts but the update always fails. I will try to visit the nearest Asus service center, but since I'm here, I created this new discussion in order to report another case and that this case might still be prevalent to a lot of kunai 3 gamepad users. I hope that Asus will raise this issue higher in their "to fix" priority list. The kunai 3 gamepad is a good product and it would be a waste if they wouldn't fix and improve it.
