Always On Display

Is there a way to have this feature on our phones? I've tried a few apps, but it isn't the same.
Any modules or rooted apps you might recommend will be greatly appreciated ????

If you will leave the phone upright, you can use an app like this: https://play.google.com/store/apps/details?id=com.plexnor.gravityscreenofffree&hl=en

Glance Plus is close, but not perfect.

"Always On" on the play store is really good. It is probably the best that I have found honestly with the most features. The developer is open to suggestions as well.

I use Tasker for that. I set it up so when connected to any power, screen time out changes to 23 hrs, 59 min, 59 sec if screen is on. When state is disconnected from power, time out changes back to 1 minute.

You can have the screen stay on when plugged in from developer options

Max OD's TMobile S7 port had the best implementation of AOD I've used, but it was still buggy and annoying...i disabled it straight away. I don't think Samsung has even had it working all that well. Different strokes and all that, but I don't see much point in the feature, makes the phone feel like an LG clamshell from '04.

I tried in on the Noble ROM. When unlocking the home screen, it would stay dark. I understand that's an issue with Dr Ketan's new ROM as well.

Hi
On the Note Edge 915 Noble Rom the screen saturates, like it is a Xray picture... But the AOD works with the fix that has been given in the third post of the Noble Rom. But the display beeing Xray'd isnt nice, so hopfully there will be a fix for this.

Forcefully Enable Always on Display Mi 10T

Is there any way to forcefully enable AOD on Mi 10T? Via build.prop or tweaking MIUI itself; I just want to try this while my phone screen is off, that's all

It's a fun novelty, we should all admit.

I tried installing the Always on apk from the m10 on my 10T but nothing changed.
Then I changed my region to India (global rom) and the AOD option appeared in settings but when I applied it, nothing happened.

Always on displays are only available on OLED screens that can illuminate single pixels. LCD will never have always on displays so this thread needs closing.

LCDs are never meant to have AODs, yes, I get the whole point out of it, but My point is, there are ways that other MIUI devices, i.e., RN9Pro curtana, with a lil bit of flashing some AOD Mods thru Magisk have proven that MIUI AOD can be enabled, what I'm trying to convey is that, os there anyone here, with the knowledge and enough curiosity that could help people like me to enjoy a bit stupid but fun way of "messing around" with the android framework, that's all. You don't need to "Close" this thread.

Honestly, ain't anyone here amazed by that MIUI AOD? It consumes power because we have an LCD panel, yes, but we can turn it off anytime. It's both the novelty and satisfaction that gave birth to this stupid but curious idea.

It's not that much of a novelty, i had aod 10 years ago on several phones... It just comes to the fact that you don't really don't need that

si think this is a good idea! probably all LCD displays know aod handling. It just doesn’t allow it because of the brutal reduction in energy use!

Iomarius said:
LCD 永远不会有 AOD，是的，我明白了全部要点，但我的观点是，其他 MIUI 设备，即 RN9Pro curtana，通过 Magisk 稍微闪烁一些 AOD Mods 已经证明了可以启用 MIUI AOD，我想传达的是，这里有任何人，有知识和足够的好奇心，可以帮助像我这样的人享受有点愚蠢但有趣的方式来“玩弄”安卓框架，仅此而已。您无需“关闭”此线程。

Question Pixel 6 (Pro) Variable Refresh Rate

Hey guys, looking for confirmation. I recently started exploring this phone's VRR to see if I could find a way to force max refresh of 90hz on the pro to try and save battery. Ran into trouble and found this video showing the phone only goes from 60-120hz:
I've heard arguments against being able to see the refresh rate with the developer options tool, as refresh rates of LPTO displays happen at lower (hardware) level than the "show refresh rate" tool (software) can view.
Many VRR displays use profiles rather than true "seemless" switching, ie: 1hz, 10hz, 11hz, 24hz, 30hz, 40hz, 60hz, 120hz.
Does anyone have the necessary expertise to tell me what's going on here? Do our Pixel 6/Pro displays have two refresh profiles, 60hz and 120hz, and that's it? Or is this a failure of the methodology being used in the above video's test? Further, is this a hardware limitation, or something that can be fixed via a software update in the future?
Thanks to anyone with some insight
*Edit* Here's a pic of the website "smartprix" claiming the P6P is variable down to 10hz

Here's another troubling post about the display on this thing, if anyone is interested. I'm hoping we can get some of these things addressed in updates, because I really love this phone. I just want to find a way to make the battery last a bit longer..
Are these issues that perhaps custom kernels may also address? Sorry if any of these are obvious questions, I just plan on keeping this phone a long time and hate seeing these head-scratching issues. Thanks

He also mentions in that thread that this is pretty much unfixable. I wouldn't bet on custom kernels etc being able to fix this.

It is fixable (in theory).
The hardware supports a variable refresh rate from 10-120 Hz, so in theory that can be used "fully". Meaning 10, 30, 60, 24, 90, whatever.
BUT - Google locks it down. As of now, we do not know why, or how.
Maybe someone will find/make a fix/a mod one day, maybe Google will do it.
Right now we do not have a fix, and don't know more. Not much more to say.

So, would it be better to force 120 Hz in developer options?

I don't see how, it would just cost more battery. The phone ramps up to 120hz fine, it's lower frequencies that are the issue. Which leads to yet another thing that's compounding battery problems

Is it possible to get different control with a custom ROM?

Interested to know if you've found any updates on this in the almost 2 years since you asked. Setting the max refresh rate to 90Hz would be cool!

Question How is That Even Possible

As you can see my phone Charges pretty fast. It Charges 0 to 100 in one hour. But charge Drains fast also like 4 and half hour screen time. Im on MIUI 13 global.

That's stock MIUI, right? It's possible you have some background stuff going on that drains the battery on a regular basis. If you haven't already, try clearing your Recents view to see if that helps.
I am using Arrow OS 12.0, myself, and ended up enabling the Developer Options selection for 'kills all activities once user leaves them'. This improved my active consumption rate from being ~8-9% per hour to ~6% per hour. You can give it a try, too!

Yes its stock. I couldnt find any app yet, im Still searching and looking for a help.

Oh, maybe you have the same issue that I had.
Check if the MIUI gallery is going crazy in the background. I have yet to figure out what caused that, but it wrecked havoc on my device.
Get something to view your CPU frequency in real time, normally all cores should idle at under 1000MHz with nothing else open in the background (I used CPU Float to check that).
If your little and/or middle cores appear to be clocked high, try to see if force closing the gallery and not reopening it helps. I fixed it for good only after having disabled its storage permission, ended up switching to google photos instead.
Hope this helps.

It looks like this and going crazy up and down all the time. I force stopped gallery and remove the permission but its Still the same.

Question Advices for a fresh user

Hi .
I'm about to get my s21 FE this week. Could you perhaps point me to the right direction and show me what are the things I should consider changing when I start using the phone.
I'm aware of the app that will make the adaptive refresh rate and I guess I'm going to use it right away.
Perhaps there are some good guides for newbies how to improve battery life etc.
I also dont want to get rid of the device warranty by doing any changes.
Thank you in advance for any help!

Hi,
To manage the refresh rate, you can use this app:
[App]Galaxy Max Hz (Refresh Rate Mods, Screen-off Mods, QS Tiles, Tasker Support and More)
About this app: Refresh Rate Mods Change default refresh rates -Easily change the overall refresh rate settings of devices supporting multiple refresh rates. -Set supported mid refresh rates as the maximum refresh rate limit for battery...
forum.xda-developers.com
But beware, the S21 FE does not support adaptive refresh, only 60 or 120 Hz.
For battery optimization, there is a lot of discussion and a lot of differing opinions.
The best way to preserve it is to try never to go below 15% charge and never above 85%..... but this is difficult to implement!!
Or, you can also pay no attention to it and plan to change the battery when it begins to show signs of weakness
Finally, you can also optimize your smartphone by following this complete guide which does not require root access and therefore does not modify it irreparably :
[DISCONTINUED] Samsung Galaxy One UI - Optimization Guide
THIS IS A SUGGESTED CONFIGURATION FOR SAMSUNG DEVICES OUT OF SUPPORT/CLOSED I - RECOMMENDED SETTINGS To Start With - Factory Reset before starting optimisations - Factory Reset after every Major update (One UI/Android) - Remove SIM before first...
forum.xda-developers.com

Great.
Thank you for the links. Going to try those when the phone arrives.
Is there any option in wellbeing that changes 100% to 80% of the battery capacity? Perhaps this could be an option to prevent it from going to 100%.

There is battery protect, it limits charging to 85%

I've applied most of the settings and now I'm trying to debloat the device. Is there any recent list for s21 fe ? There is so many samsung packages that I don't really know if I need or not... Gettting a bit complicated there.
Also I wonder about restoring app before making a phone update. Do I need to reinstall all apps that I deleted and disabled before I actually make an update? and after the update delete them again ?

You don't need to reinstall the app before an update!
