Thank you saved me a lot of money Edited: 30 may 2015 have been through 5 nexus 9 devices thanks to this app I have up because the screen bleed out never NEVER SETTLE for a less than perfect screen regardless of what people tell you and about 700 bucks later i yet to find a good nexus not only are the buttons flushed but thanks to this app it's shown me how HTC horrible quality control is thank you for such an awesome and great app because screens should not have ANY BLEED OUT.
Detected awfull Nexus 7 & 10 LCD Bought nexus 7 & 10 and used this app to test the screen because right from the start i had a doubt about poor colour reproduction it was producing, so i used this app and my doubts was correct. Light bleeds from almost everywhere and even the replacements as well. Got refunds from googlplay. A big thumbs up to the dev for creating such usefull app.
Worked like a charm ! Unfortunately display of my moto g2 has some issues. In short mine has bleed light issue.
Nexus 7 (2013) tested Checked and no light bleed. So far so good!
Major light bleed.... on my Nexus 7, which I knew, but this app showed that it's worse than I thought. :(
Does what it says Tested on the Galaxy Tab S AMOLED screen. Sure enough, virtually no backlight bleed thanks to individual pixels that are able to produce its own light.
