this really is a great app. it can help you test everything on your device.the only thing it’s missing & the only reason it’s not 5 stars is because it doesn’t have the pixel test. i used to have a Battery Life app that’s no longer on the app store that would test the screens pixel display. basically it would show the entire screen in different colors you could tap through to make sure the pixels on your screen aren’t dead. it would show all green, then you’d tap & it would show all blue, basically let you go through every color to see if a pixel is dead on your screen. i purchased it thinking it would have the dead pixel test as part of the screen tests. i would 100% give it 5 stars if this was added in the next update & i imagine it would be super simple to implement. please do consider adding this. thank you.

I hardly ever write app reviews but this app is worth it. I was looking for an easy way to test all segments on a suspect screen and was surprised how few options seemed to exist in the apps store. I went with this one because it was the only one I could find with decent reviews. I’m glad I bought it as it has so many tests available for all the discreet sensors, speakers, microphones, camera, and screen functions. Well worth it and useful!

I had a question about whether my relatively new screen is defunct. It turns out my screen is fine. It turned out that since I replaced the screen, I had to take off my protective cover and my hand was pressing the side when I didn’t think it was (causing it to do weird things). Thank you!

It works, but because the developer just uses stupid red circles to show the touches, after a few touches you can not possibly see the new vs. the old circles from each other. They just blend in and overlap and the test itself is utterly useless.I am trying to diagnose a glitchy screen that gives me spurious ghost multi touches. But this app just gives me a bunch of red circles.At a minimum alternate your color each time you see a touch. Make it so they don’t overlap so badly. And let me test the entire area of my screen. Also design it so that it highlights ghost touches and I can see if it’s counting a double touch vs. triple, vs. quadruple touch.Put some actual thought into it. This app looks like it’s version 1.0 and is a long way from being a professional grade tool as far as the touchscreen tests go.I wish I could get my money back.
