Feel like I'm a doctor, checking my phone for symptoms of bad phone disease. Definitely enjoy this app lol Really recommend using this app if you guys bought a new phone and wanna find a flaw on your device's hardware (especially the screen).
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.
Doesn't follow system settings for portrait/landscape/auto rules. Asked me to rate upon entering the app, and this is the only thing I've experienced so far; reflects poorly on how useful the rest of the app will be.
I like it quite a bit. Also useful for testing your camera's histogram accuracy. It is a bit different due to the light coming from a screen instead of a reflectory object. Very useful!
Has some sys info, the screen diagnostic is visual. Nothing for detecting physical screen damage. My screen has a small black spot, and when I lock my phone the display flashes then fails to display image even though touch still works.
Destroyed a whole horizontal pixel line of my screen, only by testing and checking simple colors with this app!
Not usable for calibrating my new TV because of this app should be able to install to TV, not only to phone or tablet. Now it shows only properties of my table and/or phone. I didn't test my phone or tablet so, full 5 stars because I didn't test any real features from this application.
Temporarily fixed burnin image on one phone. But comes back within a day. On second phone (S7), does not fix but I think it could if it would run for more than an hour at a time.
Brillient app! Everything you would need for screen testing. No annoying ads just a little one at the bottom of the screen.
All in one app to check for your screen. Very useful for testing after replacing your screen. One suffestion would be addition for screen imahe retention test
I have tried several burn-in repair tools, most with little to no success. Ran a few cycles of this one on my S9, and I think I see some decent improvement. Thank you for this tool!
Absolutely fantastic app. So many features and tests also a plethora of fixes and tools! Easily the best OLED/LCD tester on the google store
Very easy-to-use & lots of info about your device! Highly recommend this if you are in doubt with your display.
Gamma test can be improved. Currently you can see subpixel artifacts on the edges of the rectangles. Maybe it is possible to work with pixels directly instead of drawing antialiased boxes? Or just disable antialiasing somehow. Also I can see shadows of these rectangles in some gamma tests. I really doubt they should be there...
Easy to use and fun to play around with. Helped me adjust visibility settings on my Galaxy Tab A to compensate for my red-green color perception deficiency.
Best app for touch screen testing I ever used. It shows all screen details and properties.
Wrong info. It shows on my mi10i that it has a 60 Hz ref rate. But it's 120 actually (set to 120 always). Giving it q star. Also the dimensions were wrong too.
Good app. Does what it supposed to do. Simple and easy to use. I've found out that I got burn-in and got to return my phone within the warranty period.
It work for me. There are some color burning point in my display and after repair with Black and Wthite scrolling bar 😮😮 magic.. Color burning point erased.. LG G5
Great app. It provides various ways to test screen to identify if there's a problem with your screen.
Guess what, if you have a samsung phone. Go to phone and type #*0#* and then you have an inbuilt menu that does the same thing
Excellent app. Very useful while calibrating the display of a new phone.
Only downloaded the app to fix image retention. And it did so flawlessly.
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!
