    I have the LG V20 h990-ds model. I turn on the auto brightness feature but after I turn the phone off and on, the feature gets turned off by itself. Is it a bug or is it by design?
    Driving me crazy. I know there are apps to control auto brightness but I want to use the smallest number of apps possible.

    Will appreciate any help!

    I haven't noticed that specifically on my V20 (Verizon variant), but sometimes it'll stop responding to light changes and I have to turn auto brightness off and back on again to get it to respond again.

    The LG autobrightness has some funny quirks (I noticed it on an H819 [T-Mobile]), which is why I went back to using Velis Auto Brightness. It's small (only 1.24MB for the app and its storage), and it's actually better than the Android autobrightness control. You can set it to your liking, so you get full brightness in sunlight, but a dim screen even in good room lighting (or any other curve you like).

    Thanks for the replies. I'm currently using Lex Lite and it does the job, but this autobrightness quirk still seems strange to me. Didn't have such behavior on any other phone.
