UPDATE 12/21: Fixed, see thread: https://xdaforums.com/rog-phone-2/accessories/guide-asus-kunai-fixes-analog-drift-m1-t4023115
--------------------------------
Kunais definitely have an issue when moving both analogs simultaneously so I've tested EXTENSIVELY and have beaten my sticks to a pulp. If you move one at a time, no matter how hard you go at it, it won't get stuck, but as soon as you move both simultaneously (as anyone would do), that's when it starts going bonkers.
The sticks have no issues when used seperately.
So here is an interesting fact, when disconnecting the left Kunai, the right controller stops altogether. If removing the right side, the left Kunai still works. Also, the left has 3 rows of contact pins, the right has 2.
This tells me the left one should be the "master" of the two and yet, the USB-C is on the right.
Another fact, since these controllers clearly have no communication components (BT and/or Wi-Fi) the input data must travel through most likely a very thin copper wire that is embedded somewhere in the flexible back panel of the case... I'd assume there is one that goes from right to left and then another one from left to right, without looping.
Which brings me to what is definitely the scary part... The problem seems physical... If the data cable is too thin/too long and causing this issue, it will be a nearly impossible fix without damaging the case... Or, it is a software issue which seemingly bottlenecks input data and halts for a second but somehow, I doubt that because if that was the case, right side buttons as well as the right stick could get "stuck".
As it turns out, if you rotate the left stick and push buttons on the right side, a button can indeed get stuck.
Tl;dr - Does anybody have the center part to do some testing?
I feel like that piece is the key to understanding if it's a software conflict or hardware issue.
