LCD & AMOLED-Test

Freaking awesome - LG V10.. I was having this problem and the phone has this weird ghost-image for the messenger, after installing this app the problem goes away, I couldn't believe that will work as this fast, thanks alot for all the users for the very useful review and a huge thanks for the producers... Really am happy

Lightweight, simple and does what its supposed to do. Trying this app is a must do when getting a brand new phone.

Doesn't give instructions and you just sit there on a colored screen. Poor

It's Lite, without Ads, but needs improvement. Feature should be added -> "Primary LCD colors" "Automatic LCD color cycle" it's a pain in A**hole to manually swipe through colors. To make it useful, only implement those lcd base colors(red, green, blue, yellow, pink, cyan, white, black) and loop between them on an interval of 5 seconds. Then you can rename your product as "LCD Conditioner" and ship this as a well formed Android LCD "Image Retention" fix utility.

LG G4 here. Woke up today with my lockscreen burned on to my main screen. Install this and cycle through it 2 times, all burned gone! I recommend turning your screen brightness to 100 while using.

Worthless. Does nothing except for swipe colors. Does not fix anything. Does not diagnose anything. Uninstalled.

Great for checking lcd and amoled display. Especially after buying the new android device

You can clearly see the difference between Amoled and IPS LCD panel.

I think it works, but my screen is dirty

Didn't use the space with nab buttons on the bottom, useless.

I don't know what is the main thing

Displays as advertised, simple and easy.

I would give it no star I have ghost imagee visisble on my lcd I opened it for almost five hour but useless

To test the entire screen. Thanks!!!!

Do what it designed to do.

Useful app to check on lcd defect

Does not cover software buttons

Simple but usefull. Love it

(LG V20) this 100% took care of my issue.

Not 100% sure it fixes anything
