Have been reading information regarding night mode/dark mode that can reduce battery consumption..............is this something that we can do on our Oreo version of Android or do we have to wait for the Pie upgrade? Also, suggestions you guys/gals are using for similar results in longer battery life would be helpful.
I do use the Dark Theme by Samsung.

I don't even see where to use dark theme...can you help?
I am fairly certain it's an oreo Version upgrade since my brothers Motorola acquired the ability after his oreo update.
Has anyone tried HDR on YouTube after pie update, I'm not getting it to work.
This app is a life saver for anyone who suffers from "invisible" screen flickering caused by PWM backlight control. Most AMOLED displays control lower than 100% display brightness by PWM. This method is extremely easy to implement, but can cause eye strain and headaches for sensitive people. DC dimming is rare as it is hard to implement without sacrificing color accuracy. This is where OLED Saver comes in handy.
How to use:
- turn off system adaptive brightness
- install the app, allow permissions it requests and enable the service
- set minimum screen brightness to 255 if you want to have the safest value (guaranteed to have zero flickering). After further testing, values as low as 96 seems to be still safe - but test it with your phone to be sure.
- minimise the ongoing notification to hide it from lockscreen
- turn on automatic brightness change from the notification ("A")
- remove OLED Saver from battery optimizations
In some rare cases you will need to suspend the service from notification (while taking screenshots for example, app installer might need it disabled too).
If you have Tasker and root access, you can toggle the service to force 100% brightness automatically. I'm using 100% while viewing videos/pictures and taking photos.
Start service
Code:
am startservice org.js.oledsaver/.MainService
Stop service (this will remove also notification)
Code:
am stopservice org.js.oledsaver/.MainService
So far I haven't found any negative point while using this app, just wish it was included in the AOSP code so we could still use adaptive brightness. Anyway, give it a try and share your experience.
I used to have some trouble watching text on this display under certain light conditions.
I don't know if it is just a placebo effect, but since I've installed this app, I don't feel any discomfort anymore.
I also can't see any difference in picture quality.

You can easily check if it's working with another phone's camera. People have different sensitivity to PWM flickering, from none to watering eyes. You are probably somewhere in between. Without the app, I had a slight feeling like something was pulling my eyes. As soon as I enabled the app, this sensation has been gone. My wife doesn't see/feel any difference, but I left it enabled for her anyway, just to be on the safe side.
Thanks a lot for introducing this app. It works.
However I encountered a problem. With this OLED Saver activated and using GCAM to take photos, it boosts the brightness to maximum. Then I went elsewhere like home screen or other app, the auto brightness seemed not working and kept the max. brightness.
Then I tried locking the screen and unlocking, the brightness went up or down randomly, or it worked in some particular patterns I don't know. Anyway, it can't keep the brightness I set previously.
Does anyone has any idea to remedy this? Thanks a lot.

Which GCAM app do you use? I'll try it. In stock camera it doesn't behave this way.
Btw. I tried to contact the developer if he could add global intents so we could control OLED Saver with Tasker and without root, this should help in preventing this kind of behavior. No response so far though. If you are rooted you could use method mentioned in the first post.
Also I'm in touch with Velis Auto Brightness developer - this app offers much more features (customizable automatic brightness levels, apps exclusion and more) and has similar feature for OLED displays, but sadly it doesn't work on status/nav bar as of now. If he manages to use the same method as OLED Saver, we could switch to VAB app.
The GCAM version is 7.0.009.259843690.
Phone model is M1906F9SH (64G global version) with OE ROM.
Thank you.

Could you send me the link to the particular GCAM apk pls? Different authors might give slightly different results.
I'm not allowed to post link here, yet.
Please search this file name: PMGC_7.0.009_FinalBuild_V14.apk
It's what I've saved and installed.

Hm, I can't replicate this. I've installed GCAM, enabled max brightness for pictures (but it does nothing, as system brightness is at max already and real dimming is done with OLED Saver, which is not being controlled by GCAM). Moving to/from GCAM doesn't change anything. If I manually suspend OLED Saver from notification, GCAM shows max brightness correctly. On resume it returns to the expected behavior and dimmer display.
Yeah, sometimes I got what you described. Sometimes it rushes to very very bright, but sometimes it can be very dim...
I'll try reset it again and see how it goes. Thanks for your time.

I think that I saw OLED Saver "crash" once while using the phone - brightness suddenly went to max and was controlled by system. Since I removed this app from battery optimizations, it seems to be stable. Though this does not explain rapid bright/dim changes.
This looks very useful but what is it doing exactly? Is it running the screen at max brightness at all time and using some kind of overlay to dim the screen? Isn't that bad for battery life?

Yes, as you said, running HW brightness at max and putting a translucent overlay over the screen. It's basically SW implementation of DC dimming. It has a small artifacts with very low brightness, especially on grey colors, but otherwise no issues. Impact on battery should be negligible (OLED displays work different than LCD). Here is a nice article with links to more information at the end https://blog.elcomsoft.com/2019/11/...e-11-pro-and-pro-max-google-pixel-4-and-4-xl/

Has anyone used a high speed cam to determine at which brightness level the a3 flickers, or is it all level below 100%

Edit: actually PWM seems to kick in at 80% brightness and below.
Hi _mysiak_,
I changed to some other version of GCAM (without the max brightness view finder) and then this OLED Saver App is working fine afterwards. Thank you.
Then I found, when in very dim setting, occasionally, the white color (now it's actually gray) seems not stable. It could be fluctuating from neutral gray to warmer. Not intrusive, though. Do you see that?

Yes, I noticed that "slow flickering/artifacts" as well. I believe it's the side effect of DC dimming method and probably one of the reasons why it's not so widely used. From what I read, Samsung AMOLED panels are designed to be used with PWM dimming, so we probably can't avoid it with very low brightness. If it's too disturbing, I just move the OLED Saver brightness slider a bit higher (it stops completely at roughly 40% brightness). Using pitch black themes in apps helps too. Not a perfect solution but definitely better than PWM
Btw. it's the same for any app using translucent overlays, I tried a couple of them and at similar brightness, all behave the same.

It seems to be at 80% and below. 81-82% and above should be safe.

Try to change the "basic physical brightness" to value 96, artifacts don't disappear completely, but I don't notice them so often.
Level 96 in OLED Saver corresponds to HW brightness level 82%, which seems to be still free of PWM.
Thanks for the tip.
It's really works. Thanks for the tip ???
So I have the ugly stock notification panel on my P30 Pro MIUI 10.
I was wondering if there's any way of modding it without rooting.?
Thanks
You can use Power Shade on the Play store. Did have alot of fun with it.
Thank you very much, I was wondering the same thing. Now I have the notification panel as I wanted. Once again thank you very much.

Hi,
Is power shade actually fully compatible with dark mode in EMUI 10??
Cause I read that auto brightness toggle is screwed up (which I use) and others say it doesn't fully work for Quick Settings or re-asks from time to time accessibility permission. And others mention poorer battery life and performance as Power Shade is always running.
Not sure if it's worth paying for the app that might have those glitches.

Auto brightness works, but if you have that enabled then you cannot manually change brightness, the slider does nothing unless you disable auto
Ok, but how about other icons like Huawei Share that I use often? Are they still present? And how's battery life and performance? Any difference with Power Shade running all the time?

Can the brightness slider be removed from the quick settings panel? It's something that i'll never need and it just takes up room.
Hi everyone,
Android 12 introduced a feature called "Dim Screen" which allows you to further reduce your brightness than lowest possible on brightness slider, but it is missing from MIUI 13.0.4.0 Global Update for RN10 plus. Is there a way to access this feature. I'm asking because apps like Night Screen or Night Owl, which I used to rely on before dont work on Android 12. You cannot interact with UI if any app is "displaying over other apps". I really need much lower brightness at night and its became a hassle.
Anyone knows the solution?
If you're rooted, you can use cf.Lumen on the A12 MIUI ROM. It doesn't seem to have any issues with displaying over other apps, and it's a great app, one of the best of this kind, because it doesn't just put an overlay on the screen, it directly affects color channels.
Without root, I think I remember Twilight causing no issues like that on A12.
I doubt the dimming feature is accessible in MIUI, given that MIUI handles brightness quite differently.
where can i find it the dim screen feature? edit:i didn't read carefuly

In ancient looks like this:
Same here. On the Xiaomi 12X the extra dim feature is not avaiable. Latest global 13.02
Download the apps called MIUI downloader from Playstore, there was a tab called hid. Features and you will find the extra dim feature there.
Just activate it and it will be shown in control center toggle also
