Frustrated with kick sensor not working?? Here is the solution.. I have found that if you position yourself directly in front of the camera in the bumper and start your movement in front of the camera with your foot under the bumper and swipe your foot towards 1st sensor to the left of the camera (my foot swiping under the bumper just under the edge there is), then it works every time 😅.. also when you only use your mobile as a key.

ATTENTION! Only tested on Xmart OS version 4.4.1
