Attempt to invoke virtual method 'float android.view.MotionEvent.getX()' on a null object reference

See original GitHub issue

It works, but sometimes it shows this error: (Double Tap)

I don’t know how to replicate tho 😕

I don’t know if it’s related but I’ve gotten a couple of somewhat similar crashes. Please let me know if you’d prefer that UI open a new issue for it. See below:

Device was a Samsung Galaxy J7 Neo running Android 9 (SDK 28).

Any idea how I could investigate the source of this error? Thanks!
