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.
Very useful! I've used this app to find out a problem on my touchscreen that was getting me out of my nerves.
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.
Worked fine. Did what it should. Tested multi touch.
It does what it says.
LG G4 Works great.
