I have ordered 2 new units of the KingKong 2 Pro controller, by Gulikit.
On Unit 1 I have found two main issues, the first regarding a faulty detection of the Left Trigger as being pressed, and the second regarding the D-Pad.
This is the video of the Left Trigger problem, getting fixed after the recalibration procedure.
This had been done twice before, after firmware updating, but for some reason, it only worked on the third time, on the next day.
Procedure:
Turn controller off - double press Mode button
Press and hold: L, R, Left D-pad, A
The controller will vibrate once, and calibration should be done.
