[Q] non-root: even lower display brightness?

anyone know of a way to get the HTCONE/sprint non-rooted phone to go lower in display brightness?
if i use it as an alarm clock on my nightstand it lights up the entire room on lowest brightness.
thanks!

Look for an app called "Lux Auto Brightness" on the Play Store. There is a lite version that you can try out. It's allowed me to go in the negative brightness and it works pretty well.

thanks. don't suppose this will work with locale...
maybe i'll have to write my own pluggin

I haven't used Lux but I really like Screen Filter for the same job: it has a huge range of dimming up to total blackness and can turn off the capacitative button backlight (requires turning the screen off and back on) which is a big deal when viewing a dimmed screen in a dark room. And the full version is free and ad-free as well.

thanks again for your replies. looks like Lux works with locale.
but... it's not quite working for me yet (setting to negative values of brighness at certain times, etc doesn't seem to work)
i'll keep trying. thankfully there is a trial version

Brightness slider, auto with +/- option?

So I can select "auto" brightness by the slider on the notification panel. When I move the slider, auto is unchecked. BUT, I know since I've had the S5 over the past few weeks, I've had the slider show a +/- option that allowed auto to remained checked while you could move the slider between like +3 and -3 for the relative level of auto you want.
I know this type of option can be achieved through various 3rd party apps, but is there any way to enable it from stock? I'm just confused because I know I've had this option, but I haven't used any type of brightness app, and now the option is gone. I did have wanam Xposed installed before...does that add the option?

Hmm, looks like this is an option in wanam Xposed and probably a default option so I was seeing it when I had that installed... Wanam says:
Use Auto-Brightness Detail*- Enables a +/- 5 slider for auto-brightness

was the auto brightness fine adjustment ever working for you? i havw wanam on my s4 and my s5, auto brightness adjustment doesn't work on either. maybe im doing something wrong

I believe it was working when I had wanam installed, but I honestly didn't really test it out...and I took off Xposed framework for the time being.

man. i really wish i knew why mine doesnt work on 2 different devices. i spent hours searching and reading forum posts and found no answers. i know it works on TW because i had some TW rom that had it and it worked great, but i ditched the rom casue there were things it was missing and some things i didnt like.

I did see that Lux Auto Brightness and Velix Auto Brightness might provide good 3rd party solutions to better personalized brightness control fwiw.

Ive tried lux and some others. They either worked great and killed my battery. Or didnt work woth. ****

Good to know those are battery killers, I hadn't tried them our yet myself.

Lux user here, paying user actually, works great for me, no significant drop in battery unless im in an area where the screen is staying super bright.

Good to know this as well, was thinking of trying lux or velix one of these days. Have you tried velix?

Lolipop Screen Brightness

Hi there!
For sometime now I want to move to LP but I find too many things that are missing compare to my current KK.
I'm using Lux Auto Brightness on my current device and on LP it caused so problems (fullscreen overlay, presist notification etc..)
I was wondering how is the stock auto brightness of the LP (if it's any different from the current KK) or is there any alternative for LP to the Lux?
Thanks!

I absolutely love the stock brightness settings. You set a desired screen brightness with the slider and it adapts the screen in a way, so that depending on environment light you perceive the screen at the same brightness u initially set. In my opinion it works really, really well.

What is your opinion about the brightness compare to KK?
I recall seeing some very poor performance form the stock brightness management in sunlight.

Stock auto-brightness (erm, I mean "adaptive brightness") sucks on Lollipop IMO. It's another example of something that wasn't broken but Google tried to fix it anyway and utterly borked it in the process.
My experience is that it does not "adapt" nearly enough. If I set the slider to the right level in daylight, when I go into a dark room I am blinded. If I set the slider to the right level in a dark room, when I go into sunlight I cannot see the screen. Frankly I cannot see the screen adapting at all. If it is adapting then it's in within a very narrow range. I even did a software repair to see if that would solve it, but it didn't.
I've not used Lux, but I've not heard good things about it in Lollipop and am loathed to install an app to do something that previously was handled fin by the OS. Stock auto-brightness worked very well for me in KK.

Are you sure that you have adaptive brightness enabled at all? I can see it adapt quite clearly on mine.

I'm using Lux on LP and don't have any issues. The persistent notification can be set so it's only visible in the swiped down notification view, but not perpetually visible in the notification bar (in Lux settings, set notification visibility to lowest priority). What do you mean by "fullscreen overlay?"

You need to add Package installer and SuperSU to the sleep list in Lux.

I just faceplamed myself so hard

I think I found the problem; when battery saver mode is enabled, when it kicks in, it will set your screen brightness to a certain fixed level. But when you charge the phone again and battery saver mode deactivates, it will not automatically re-enable adaptive brightness, so you need to re-enable it manually.

My experience was that kitkat was better on the screen brightness. Lollipop works fine and adapts well, except that in bright sunlight it won't turn up the brightness as much as kitkat did.

Is auto brightness working good ?

I seach many threads but in my case it works but I have a probleme for having the REAL auto brightness with my Z3C.
I mean... If I disable the auto brightness in display settings an put the maximum brigtness it's very high, and when I check the auto brightness and put the brightness (notification bar) to maximum and switch between auto and not auto... YES there is a difference, the auto mode is less bright, so yes the auto brightness option works because i see a difference... I gess
BUT... at night when the room is COMPLETLY dark (yes because I sleep in the dark lol) the brightness is very bright for me, too bright. And I go to the notification bar and put it at less... but wait! This not my definition of "auto brightness" if I have to manage it. For me (maybe I'm weird, tell me) if auto brightness is enabled, when the light sensor see a COMPLETE DARK room the brightness should be at minimum, am I right???
And, with all my previous smartphones, the auto mode was with the brightness bar in notifications bar and if I check the auto mode, the brightness setting bar is desabled... and if I setup the brighness bar, the auto brightness check is disabled... etc
So why my Z3C haven't an real auto brightness? Why can I enable the option in settings but set the brightness bar too? Why in a complete dark the brightness is too high and not at minimum? Because in the morning in the dark if I set it at minimum, later I have to set it more bright because it's too low at the day ligh... BUT I'M IN AUTO MODE IN THE DISPLAY SETTINGS!!!
It's like I have the auto mode and the right to set the brightness too... not logic! If I check the auto mode it's because I don't want to setup brighness bet the device must do it for me like my others phones...
Is it normal?
Thank you for help...

Its normal, auto brightness on the Z3 has a very narrow range of auto adjustment. So exactly like you are saying its either too bright at night or too dark in bright light. Do yourself a favor and use the app LUX, I think there is a free version to try. My auto brightness now works as it should, bright enough to read in sunlight and dim at night so I'm not blinded. You can tweak the values for every type of.light you are in, works great.

Do you have Lollipop on your phone?
Do you know that in Lollipop there is no Auto-Brightness anymore, there's "Adaptive Brightness", and it scales less, which explains your experience (and you're not the only one)?

It's was called something with "adaptive" in Kitkat, too.
You can just set the slider to the minimum, then it won't be too bright in the dark and it'll get bright enough in sunlight...

Any way to reduce minimum brightness?

Little background: somewhere in kernel code or some other core module of the operation system manufacturers or ROM creators set minimum brightness value for the device. This value was in some of my other devices called min_brightness. I remember faintly that I was able to set the value by running some script in Init.d. Unfortunately I did it several years ago for my other device and cannot remember the details.
The minimum brightness in Colt OS is 31 and seems to be similar other roms, which I tried.
Another option to set the value is Xposed module called Minimum Brightness. Unfortunately it has zero effect on my device. forum.xda-developers.com/xposed/modules/mod-minimum-brightness-t2993161/amp/
Another option is to use app called Brightness Tweak, which does its job somewhat but the result is not exactly desirable. The problem is that it makes the brightness curve not smooth and setting semi-bright values is impossible. It is however able to set the value to 1. https://forum.xda-developers.com/android/apps-games/app-brightness-tweak-t3339579
By the way, I find screen filter apps in adequate because they reduce contrast and add complexity to setting the brightness. Setting minimum brightness affects swipe status bar and brightness sliders as well as auto brightness functionalities. In addition MX Player.

Try to use "ScreenDim" app

Thanks for the suggestion. I tried the app, but in my opinion the brightness adjustment method is very convenient. The is no slider in notification or sliding status bar. Also the min brightness is not adjusted globally so other brightness adjustment method are unaffected.

Hi, @wwwwe did you actually solve the problem?

No + the phone is broken already. It wont keep charge anymore.
