User reviews

Very handy screen/display utility that helped diagnose several issues with the touchscreen on my previous phone. Would be 5 stars were it not for the ads (which I do get are there to support the app, but they still leave my phone vulnerable to potential malware served via ads).

I don't know how, but this fixed the problem I was having. my screen was darker with this horrid cast over it. seemed to happen out of no where. but then I did a test in this app that changed the contrast on my phone. when I bumped it up through this app, all of a sudden my screen was clear again and had its normal brightness back. however, I have learned my gamma is way off. 😆 I'm just happy I don't have to replace my phone just yet.

Full disclosure: I've used both RELEASE & BETA versions since 2016 & find it superior for function testing & pixel analysis of modern color touchscreens incl. AMOLED. It CAN lessen or eliminate burn-in on SOME screens. It CANNOT FIX physical screen/ digitizer damage! To brain dead user "Coyote," dude, this app is named "Display Tester," not... "FREE DEFECTIVE DISPLAY REPLACEMENT FOR IDIOTS!" Honestly. With realistic expectations, you should find this display toolbox extremely useful. *Peace*
