While breaking blocks and moving at the same time, your phone vibrates. When breaking blocks while standing still, your phone doesn't​ vibrate. Seems like a bug to me, so I thought you should know...

On my iPhone 8 in 1.14.60 I get no vibration at all when breaking blocks, whether moving or not. I verified that the setting slider is "on" in touch controls.
