Filter Your Screen App
The "Filter Your Screen - Free" app has dramatically improved video playback using the LG Video viewer, BS Player, and MX Player. The settings that work for me are: Alpha 30; Red 200; Green 200 and Blue 220. I'm sure there are many variations, but I tried to keep it simple.
When not viewing a video, I turn the Filter off and it seems to help extend battery life.
One question: Does anyone have any experience with this app? If so, does it damage a display over time?
