EDIT: I just noticed the screen recorder doesn't catch the variation of luminosity so the video is useless, sorry

EDIT2: I changed the video with one made with another phone on a phone so the change of luminosity can be detected.

LNReader version

1.1.18

Android version

Android 8 miui 8

Device

huawei p8 lite 2018

Other details

EDIT2: i did multiple videos and i noticed that the app dimmed only after i went to the next chapter. My first attempt i just waited on the first chapter of "resume" button without changing chapter and the app didn't dim at all after a minute. Then i changed chapter with the button > and some time after the app dimmed (video)
