Comments on Display Tester for Android

★★★★★ MHK · Aug 7, 2025

Works well. No stupid ads. Everything needed to test a display is free. No pay wall. Extra features need to be purchased but that's fine. Recommended.

★★★★★ Brendon Foley · Sep 12, 2022

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*

★★★★★ supergamer186 · Aug 25, 2022

This app can fix burn in and show you what could he wrong with your display - it does strictly what it says it does, and it does so impressively. However, dead pixels or digitizer problems can only be fixed at a repair shop, and I see this app being useful to phone fixing dudes!

Could not find anything to test the brightness. Seems a pretty basic issue

★☆☆☆☆ Charlene Ham · Dec 19, 2022

Confusing and cannot locate in app help. The tests mean absolutely nothing to me, the data means absolutely nothing to me. Uninstalling.

★☆☆☆☆ Nitesh K. K (Nitesh kumar) · Mar 6, 2026

Incorrect information... my phone got 12 bit display as per company claim, but it shows 8bit... xiaomi 15 ultra

★☆☆☆☆ Alexandru · Mar 2, 2024

Unable to test the app without cookie consent, therefor the app does not work.

★☆☆☆☆ Ari Skyes (Tim Hall) · Jul 27, 2022

Doesn't repair the part of the screen that senses touch even if you pay. Not worth it
