Simple but does the job If, like me, your phone or tablet screen sometimes seems to be responding incorrectly this is a small and simple test to confirm it. Does exactly what you'd expect, no more, no less. Thanks to the dev for a decent little app that does the job.
Does the job as advertised. Trying to find out why my LG G4 would sometimes be unresponsive and refuses to wake up when I tap.
Very useful! I've used this app to find out a problem on my touchscreen that was getting me out of my nerves.
Worked fine. Did what it should. Tested multi touch.
It does what it says.
LG G4 Works great.
