How does it work?? it doesn't do crap about PWM. lcd still flickers at the same rate, just because you put darker foreground on top it makes less bright flicker-but it still the same flicker. also how do we know you dont keylog clicks and so on? :D Overlay apps are most security risk app types.

I think this app works better, if you're using auto-brightness - all you need it's disable system auto-brightness and set system britness to max, then enable option, which called "service" in app

Yeah that's the BEST way of draining battery. THE ONLY correct way of using such apps is to do brightness to MIN and only then use it.

Does this drain battery . However i noticed it doesn't heat up the device . So does that mean it doesn't drain the battery since no increased power consumption?

@Wootever I lost the file of your first version of pwm-free.apk, which overrides the android slider on a rooted phone. Can you share this apk file again please?

Please release source of the app. I'm actively looking for app with this functionality. For security reasons only way I see is to install open-source app (due to fact that app has access to accessibility features).

Installed it on my Tab S6 (no root), works perfectly.

And for what it's worth, this is what I'm getting on my oscilloscope connected to an OPT101 sensor...

Normal operation, low brightness:

With this app:

Thank you @Wootever !

Sir,
My stock rom had dc Dimming and I loved it. Since I changed my rom to Pixel Experience I had excessive flickering with on screen which was solved using this app.

The only downside is when I'm inside a video player e.g Mx or YouTube, I can't control the brightness using swipe up/down gestures.
Is there a fix for that?

Thanks

    Not sure why the installation is prevented.
    The application itself just creates an accessibility overlay and changes the permission for /sys/class/backlight/panel/brightness to prevent access from liblights.

    Edit:
    Seems like this is the common behaviour for non-playstore apps: disable Google Play Protect

    Found the causing issue with the help of the android emulator.
    I updated the download link on the original post, please try if it's working correctly now.
