NileshWe are aware of this issue and are actively investigating. There is a more extensive discussion in another thread. Closing this one so we can merge the discussion.
The air trigger on the right (lower one ) has started to respond sporadically after the lasted firmware update. It seems like the issue is with the new resting fingers feature which allows you to keep your finger and press continuously to trigger the buttons. You can get somewhat proper response when your finger is resting on the triggers while configuring it but it does not respond well during gaming.
I was always sceptical while getting Asus as it is not know much for their software support unlike its competitors like 1+ .
I hope they fix this issue ASAP and also come up soon with Android 10 update.
