This app will create a filter to reduce color tint on the screen or use this app to change your screen temperature.
You can also use this app to dim your screen for night if it is too bright.
You can see result of filter by using 39 screen test 39 which is included in this app you can also use this feature to find dead pixels on your screen.
Furthermore this app includes a funny feature filter effect which you can use 39 scanline effect 39 to display scan lines on your screen to make it looks like crt monitor.
Note please read 39 term of use 39 and 39 instruction 39 in this app carefully before using it.
Oled screen owner please read (amoled screen of samsung galaxy s super amoled plus screen of samsung galaxy s ii etc.
) You should use only white gray or black filter only.
Using color filter (not white gray or black) for a long time may cause your screen more color tint.
(It 39 s about oled screen property not my fault) using any color filter other than black will cause black pixel being not 39 true black 39 pixel anymore.
(That means some power is required for black pixel) if the filter does not cover full screen please uninstall this app because this may cause irregular color burn to your screen.
Please support us by rate review this app if you like it.
Thank you very much.
Known issue the filter disappear randomly.
This is because android system kills some services due to low memory condition.
Sadly this cannot be fixed.
However the system will start killed services again in a few seconds.
So you don 39 t have to start service by yourself.
