I have an Asus Zenfone 2 with Android 6.0.1 on it.
Up until recently, when the phone was locked I could double-tap to launch the lock screen. I don't remember what I messed with, but recently, when the phone is locked double-tap doesn't do anything.
I would like to emphasize that the touch-screen works just fine while device is awake, it's just the double-tapping to wake device from sleep/lock mode that doesn't.
I tried searching the phone settings for a corresponding setting but didn't find. Is there a setting I should be aware of?
I did replace the screen & digitizer recently, could it be the reason? Touch works totally well while device is on.
The options Settings🡒Zen Motion🡒
One Hand Mode🡒Quick trigger
and Touch Gesture🡒Screen off are both enabled.
