Screen Brightness - Samsung Galaxy Note 9 Questions & Answers

So I have an annoyance that I was hoping someone has a fix for. I'm using a wireless charger, Samsung Duo, to charge my phone and S3 at night. When my alarm goes off in the morning and I swipe to shut it off my screen goes to MAXIMUM BRIGHTNESS. This is on the lock screen and it eventually times out. But when I take the phone off the charger, it again goes to MAXIMUM BRIGHTNESS. I'm not kidding when I say it lights up the entire bedroom like a swat helicopter is outside my window with a spotlight! Is this a bug or is there a setting I'm missing?!

Set Auto brightness on a schedule - or - set blue light filter on a schedule - auto does indeed do some unusual stuff.

So it's just the lock screen. As soon as I unlock the phone the screen goes to auto-brightness.

[Q] Screen Dims on low battery even when Power saver is turned off.

Hi,
My Screen Dims on low battery, even when Power saver is turned off. This behaviour shows since update to 4.1.
The integrated Power Saver is set to :
Turn Power saver on : at 50% battery level
Brightness : 50% Brigtness
Powersaver : OFF
But still when 5% Battery is reached, the screen goes totally dark.
So dark I cannot read it most of the time. I have to use my hand to cover for shadow, set the brightness up, and then I can use my phone again. This makes toe phone unusable when battery is low.
I hate this behaviour and would like to disable this.
How do I disable it ?
As mentioned, this was not the case with Android 4.0.3 (stock, rooted), it happens since I updated to 4.1.2 (stock, rooted)
The intuitive place to look ws the power saver, but those settings seem not to change anything.
I have searched the net and these forums, but could not find a place where to correct this settings.
I would like the screen to remain it's last setting, not dim at all.
Please help.
You didn't set the brightness to auto, did you? Because this is maybe the cause of dimming. I'm not sure but that's my first thought.

Nope, tried both, auto and non-auto, in both cases when the 5% battery warning comes, screen is set to lowest possible level automatically, even in bright sunlight outside. In winter maybe, but in summer it suxx. Some automatic adjustment according to ambient light -might- be ok, but I would prefer that the backlight level is not changed at all.
Are you on stock? Or any custom rom?
I think you can maybe change this setting in build.prop or smth similar,
but I'm not that good when it comes to this.
Sent from my LG-P880
As I said in the first post, I use stock rom.
I have now looked through build.prop file. There is a " #Backlight " section, in there is some " ro.lge.lcd_default_brightness=146 " entry. I will change it and see what happens when I hit 5% battery. But since there is no other setting (like when battery below 5%) this does not look very promising..
Does your P880 show the same behaviour ?
It actually did the same when I was on stock (now I'm on WerewolfJB) but it didn't bother me back then (almost never got my phone below 5% battery.
And because I'm not on stock I can not look for the right line in build.prop or other system config files.

So there is no "OFF" in the powersaver, it defaults to some weird settings when switched "OFF" ?
I will try that too.

thanks the root dim it does work, you have no idea how long i search for this.Funny thing i came across this root app like 5 or 6 times and didn't think it would work cause i have lux dim the other root app and that one does bring the display back to 100 percent bright who would thought that the fix was this simple and yes like you say every time you lock the device it brings you back to dim mode but if you open the app and bring the slider all the way up it stays like that at 100 brightness, done that on my rooted galaxy s4 from cricket it works yey.

Always On Display with Edge Only

Hi,
I realized that with the Always on Display and with the setting for Edge only, I still see the stars in the background (using the default wallpaper). Doesn't this mean that even more battery is being used than with the standard full screen Always on Display? Isn't it supposed to only use certain LED's on the screen to conserve battery? If so, is it not possible to have the Edge setting on and save battery by disabling the background?
You could try not using one of the built in live wallpapers, that's where the stars come from.
Hope this helps.

So does anyone actually use the always on display feature? Seems like it wastes alot of battery
Someone will help you
I don't personally, no point using the battery when your not using the phone, I just see if the led is flashing or not.

About 3% to 5% in my experience.
You can turn on AOD feature, but when you put the phone on the desk for a long time without touching it, just put a small piece of paper (sticky paper) over the top of the screen (above the proximity sensor).
That way the AOD screen will be turned off in a couple of seconds.
When you need to check time or notifications, just lift up the sticky paper and the AOD will come back on.
You can save several % of battery using this way.

That, or face down
Weird. Mines on with a custom picture ( I converted to grey scale ) and unplugged overnight i only lose about 3-5% total. I haven't tested without AOD but it can't be using more than 2-3% tops as I'm sure the system is using up most of the battery while I sleep.
Sent from my SM-N950U using Tapatalk
I have a custom AOD and battery life is fine. Its good to glance and see the time without having to pick it up and unlocking.
If your worried turn it off or flip the phone face down. With quick charge on the phone does it really matter?

Refresh luminosity display

Hi, I would like to know if you too when I turn on the screen is as if it refreshes before turning on.
And the same thing when I turn off the screen and turn on the always on display it refreshes the brightness of luminosty the hour before decreasing intensity.
Thanks
Factory reset fixed this for me. Out of the box, it did not fair well and I noticed this after a day of use.
I'm on day 9 of the reset (recovery side), and it is going well.

Question Bixby Routines - Share Ideas?

Just got the S21 Ultra (from note 8). Stumbled upon Bixby Routines. It's great.
Always tried using Tasker but never used it much because it wasn't as easy as using Bixby Routines. Tried using similar apps as well but they never seemed to work well.
So far I've got auto-rotate for when I use video watching apps such as YouTube. Power Saving mode while I'm asleep.
Care to share some ideas?
Love Tasker but now giving a chance for Bixby Routines. So far I have set driving profile to start playing YouTube music, set audio to 100%, turn Dolby on, keep phone unlocked. Then Show AOD when charging, auto rotate on when YouTube is launched. Would like them to go crazy like tasker with some Good lock module but doubt it Had few htlm get task so I might go back to Tasker, but imo it should drain more battery compared to Bixby Routines
When i go to work, since i don't touch my phone that often, it auto changes resolution to fullHD, and turns on AOD + turns off bluetooth.
During the night turns on energy saving and airplane mode
Wireless charging between 10p - 7a will NOT fast charge so the charger fans aren't buzzing on my nightstand next to my head.
I hated everything Bixby but I see that I now have to use routines.
Good topic. How to see more useful usages posted.
I use Routines with my Android Car Stereo to Automatically start the Hotspot when it connects to my Cars bluetooth. It also turns up the volume on the phone and reads aloud text messages.
Definitely looking forward to a couple new ideas myself.
AOD & Sync on when charging, off when not charging (apps like whatsapp and outlook have their own sync which isn't affected by this)
Button on my homepage for 5G/4G
Power saving to turn on at 20% (I only turn this on if I plan to go out for the day)
Is there a way to perform an action on switching out of one app to another e.g. To close the app you switch from e.g. Chrome, so that it doesn't chew up battery in the background? Or when closing an app to put it to deep sleep?
I've set it to disable 120 Hz in apps like YouTube and tiktok and games where I wouldn't notice it anyway.
Also set network mode to 3G and disable data when connected to WiFi.

So I think the WiFi one is sort of redundant as your mobile data swtiches off if you're on WiFi with WiFi calling.
The YouTube one is actually a great spot - at low brightness the screen stays in high refresh mode, so forcing it to switch to 60 is useful!
I created a button to force to 2G only in areas where reception is poor and i dont require mobile data (2g gives better reception).
But does anyone know where this button can be used other than as a widget on homescreen?
Set location services on when opening google maps
Play playlist from spotify when bluetooth connect to my car
Put on do not disturb when opening camera application
I love bixby routines, the only thing i keep after debloating a Samsung phone
Anandtech has a write-up on the S21U display. It appears it has the same odd behavior of forcing 120hz full time during low ambient lighting, like the Note 20. The screen therefore consumes more power in dark rooms than in a bright setting. I have an (arguably bad) habit of reading my phone in bed before I fall asleep, and before I get up. So I've set a routine to switch in/out of adaptive mode during my normal bed times, so much of my usage in darkness is in 60hz mode to save battery.

It does this because 60hz changes the tint at low brightness. The oneplus 8pro was bad for this, you could see the display flicker and change tint when the refresh rate changed at low brightness , it was horrible.

I can't comment from personal experience, but from the Anandtech article:
it’s still not exactly clear at to the technical reason why Samsung is employing this limitation in the first place, as I’m not seeing any difference at all in the screen quality when tricking the phone’s ambient brightness sensor and it switching between VRR/LFD on and off.

Regardless, switching to 60hz is a solution if you want to prioritize battery life in those conditions.

Hmmm, I set a routine @ 10PM to switch to 60hz mode, that was supposed to end at 7AM with the actions reversed. It didn't switch to 60hz mode @ 10PM, so I manually switched it, and it didn't revert @ 7AM. I'll try two distinct routines.
EDIT: I set up a distinct routine to set to 60hz AFTER the existing "time period" routine, and the existing time period routine took effect properly this time, so the redundant distinct routine wasn't needed. Don't know why it didn't work the first night.
Brightness turned down and Power Saving mode turned on during my sleeping hours.
I always leave my phone unplugged while sleeping (charge fully before sleep).
I guess if I were to charge while sleeping, I'd plug into a smart plug, then have the plug turn off after the charge reached 100.

Yeah, a couple times my YouTube rotate didn't turn on. But on my wife's note 10 plus, so far has been flawless.
Just bumping this up since Routines is very useful. Been using this since my last phone and it made life a bit easier.
My settings are:
1. IF connected to home wifi, THEN keep phone unlocked.
2. IF charging, THEN sync is on.
3. IF connected to car bluetooth, THEN media volume is set to max and play favorite playlist on spotify.
4. IF time period (12AM-6AM), THEN power saving mode on, DND on, bluetooth off, NFC off.
5. IF camera app opened, THEN DND on.

Oh, gave me a great idea of keeping phone unlocked! thanks. I'll have to set one to keep phone unlocked when hooked up to android auto or the car BT.
I mess with my kids with the Low Battery Announcement (Phone needs charging, Bruh. No Cap). Lol
If it isn't connected to my Home WiFi between the hours of 10PM and 8AM, it alerts me because this typically means that the power has gone out.

Question Prevent screen brightness dropping automatically

This is probably the worst issue I have with the phone, it seems to drop screen brightness when it heats up, which more likely than not happens when using the phone in direct sunlight, making what is generally a bright screen under sunlight become a pain to use.
I'm not exactly a heavy phone user, so I'd much rather keep the phone at max brightness for short periods, even if it heats up a little. Anyone had any luck disabling this safety feature?

Yes, it was all turned off, but in the meanwhile I cleared the data for Device Health Services and it seems to have stopped sudden changes in brightness, it would visibly brighten up the display going from indoors to outdoors before.
Seems it was still retaining some adaptive brightness settings even after having disabled it. Will test if further tomorrow to see if that fixed it.

Well good luck bud!
Well, it still dims and brightens the display, to a lesser extent now, but I'm starting to doubt it's due to heating. Heating it up with intensive use while keeping it in bright conditions keeps the display at maximum, but changing lighting conditions like going indoors or covering the light sensor causes it to dim the display.
Is this a bug or a feature, I've seen people elsewhere complaining about this, so it's not a unique occurence.
