    I have a projector with an Android OS,
    Long story short, it shutdown itself, and when I turn on it back, the display is blurry, I've been rotating the lens to find the focus point is still blurry at the best focus point,
    At this point I thought it was a problem with the lens, so I took it apart, and I didn't find any damage, everything was normal.
    finally, I took the initiative to reset the Android OS, and it turned out that it was true, the screen became more focused like before the problem arose,

    the question is ?
    What causes the Android OS to show a blurry screen?
    so it means there is a config for screen sharpness in android os?
    how to access that config? because I think my projector is still not sharp enough, and we can assume it because of the firmware itself right ??

    There is no general "screen sharpness" setting in Android, though few of us will have any experience with android-based projectors and they may have settings or options that most android devices do not (and may also lack options that other devices have). Also it may depend on what Android version you are running and who the manufacturer is.

    Recent Android versions may have a "display size" item in Settings > Display > Advanced, but that basically scales some items on the screen rather than affecting screen resolution. The "developer options" menu, if you can access that(*), usually has a dpi setting (called, unhelpfully, "smallest width" on my device). Again the main effect of that is scaling of UI elements (e.g. if I fiddle with that my wallpaper is unaffected), so it doesn't quite sound like what you see.

    If you were rooted and messing with kernel settings that would be different, but we're talking about stuff that is hard-coded there and so not something that can spontaneously change or be altered by the user without root access (and unless this is a very strange device you would know if you were rooted).

    (*) To access Developer Options go into your Settings, find the "build number" in the software information, and tap on it repeatedly. It will eventually tell you that you are now a developer. But there are devices which simply don't have this menu/where it has been locked rather than simply hidden behind an Easter Egg, so I can't guarantee that this will work for you.

    this device is already rooted from the factory..... yeah I'm talking about core level config, because there nothing even simple screen setting
    and also this device has issue in displaying video, seems that the codec config oversharpened the video output which become smudges artefact ...
    this is android TV OS (Pie)
