[App] Display Tester
DisplayTester makes it possible to test almost every aspect of your device’s LCD/OLED screen.
Using Google Cast it is possible to test the display quality of your TV. It is designed to allow full screen testing also on devices with soft keys (hiding the soft keys in ICS and later, immersive mode in KitKat and later).
Free features
Dead pixel test: detect “dead pixels” by displaying a series of solid background color pages
Color tests: contrast, gradient (banding) and saturation tests
Gamma calibration tests (grey/red/green/blue)
Viewing angle tests (This is useless for OLED displays)
Wide gamut color test
Multi-touch test
Display performance tests
Repair burn in – scrolling black & white bars
Display measures info: screen size, GPU type, dpi, density-independent pixel size, OpenGL 1.x info, pixel format
Real world pictures for reference and comparison
4-color gradient test with orientation change correction (Android 2.2 and higher)
Pixel format & dithering tests
Built-in font styles test
Manually DPI measurement
Color charts
Touch screen dead spot tester
System Fonts tester

Pro features
Full Google Cast support
Repair burn in – noise (white, b&w, red, green, blue)
Soft key hiding in ICS/Honeycomb/JellyBean
Use the preferences menu option for this or simply long touch the display during a test is running.
Gestures
Slide left-right: change test image
Slide up-down: change brightness
Long touch: switch between full screen and normal screen (Android 3.0 and higher)
Double tap: hide or show the test specific settings dialogue (if available)
When the soft keys are hidden it is not easy to advance to the next screen: First tap to make the buttons appear, then a quick swipe for the next screen before the buttons are hidden again.
Please consider purchasing the Pro version to support further development.

Display Tester user reviews :
The burn in fixer did it’s best, actually works. My phone is prone to burn in since I read allot of web news and usually stick in a position where I don’t scroll for few minutes. All the other tests is great info too! Also the ads, for once, in a free application, aren’t annoying!! I don’t mind the ads in this app. I haven’t gotten any pop up ads, will change my review if wasn’t occur, I hope not.
The gamma testing is incredibly useful and unique thanks!
I’ve never had much luck with these apps on AMOLED but decided to give it a shot on an old Nexus 6. I must say that the burned-in notification and navigation bar buttons area is significantly less noticable than before. I thought at first it was a placebo until I launched a few apps where it was most noticable and the results are true.
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*
The app offers some really interesting tests to check if your display any kind of issue, either technical (dead pixels, burn-in), or visual (color banding, saturation). seems like a great tool to have if you’re having issues with your screen!
I used Waze for a 8 hour trip, on my S8, and after that I end up with big parts display burn in. Downloaded and tested the “black & white scrolling bars” from app multiple session, for 10 minute (5 time) and 1 with 30 minutes, and it fixed the display. Maybe it did help also discovering immediately the burn in and using the app. For me it helped. I Did not used other functions of the app.
Best app to test your phone screen or display. Been using it for months now and im quite satisfied with the features of the app. If your phone is not working properly be because you dropped it, this app can be used to test your phone screen if there are dead pixels in the screen.
Impressed. It does what it says it does. Transparent ad usage. The test are all free. The repair option offer one free options, but is the best. Long time since I haven’t felt no scam by a free app. Sincerely, props to you dev!
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!
