Minimum brightness - Samsung Galaxy S9+ Real Life Review

You don't want to give your significant other yet another reason to yell at you while you're reading XDA in bed. Rate this thread to express what you think of the Samsung Galaxy S9+'s display minimum dimness. A higher rating indicates that the display can get extremely dim, ideal for reading in very dark environments.

As always with Samsung OLEDs, minimum brightness is insanely low and maximum brightness is great

i saw a curioius thing and i want to know if it is normal: in a dark room the auto brightness is at minimum of course, but if i turn on the screen when it is locked, so the brightness is at max for a few seconds before to return at minimum again. is it normal?

The brightness are low enough when reading XDA on Tapatalk in Night mode setting. But much to bright on low screen even with the background set as black. Anything white background and the room lights up much to much and my eyes hurt for a minute before getting used to it.
Any suggestion how to solve this? Can we ask for a larger adjustments towers lower light setting?

The lowest setting really is too bright, custom kernels do kind of help with the problem, but they require the setting to be toggled on/off. Gravity box with xposed has the ability to reduce minimum brightness, but that voids safety net. It would be great if it could be done systemlessly with a module.

Turn on battery saver for even lower brightness!
I use an app called 'screen filter'. It works great at night.

Unfortunately that does not make much difference on my phone. But the night mode app works really good. Nice tint to when the blue light is filtered out after a bit of use to get used to it

I use a very good app, blue light filter.
It works very well.

Lux lite is an amazing app for auto brightness and it has a night mode that allows you to read easy at night. Just check it out you'll be happy.
Stock rom can go aa dim as possible.

Display brightness is reduced, after taking a photo

Hi there, on my U11 and U11+ the brightness of the screen is reduced almost immediately, after i take a photo.
This is very annoying, cause i can't see the pic a took seconds later and need to increase manually the brightness.
Did you notice same issue? Only HTC'S are doing this.

What are your brightness values for the phones? Camera app will boost brightness to the max, but once you take the photo it will return to your brightness settings

i have adaptive brightness at bout 50%. I think that the problem is that it's maximizing brightness the moment you are taking the photo and after that is getting very dim and the big difference is annoying.. Brightness isn't stable as on my pixel 2 xl.

Yep, better use 100% brightness Auto outdoors in the day, but yes there is definitely an automatic brightness problem with U11+, if 50% and less it can go very dim in a second with the same lighting conditions, usually in low light.
HTC software team is completely denying many things and repeated the same ''bugs'' in U12+

Outdoor visibility (max brightness)

Rate this thread to express how well you can see the OnePlus 6T's display outdoors. In case you've been playing Minecraft for 18 months straight, you might not known how to get outside anymore. Well, find the door and walk through it. A higher rating indicates that it has very high maximum brightness and thus fantastic outdoor visibility in direct sunlight.

Ok well here I go, I see a ton of views in this section but no comments.
First of all, I'm coming from a Moto Z2 Play and a OnePlus 3T:
The screen brightness of the OnePlus 6T is the major letdown I ever had, it is miserable, sad, despicable... Here is the deal, if I set the screen to 100% brightness in the O6T, it equals to anywhere around 85% or less of the max brightness in my 1 year old Moto Z2 Play !! also, the OnePlus 3T is brighter than the O6T by a tiny notch, but I have to add that my OnePlus 3T is 2 years old and noticeably lost its max brightness, but it still beats the O6T!!!!
If you are wondering about my device, I went to 2 T-mobile stores in the area and compared brightness, they are the same as my unit, so it is safe to say that the O6T is a disappointing device when it comes to screen brightness...
I will edit this post if I get more info or if I need to correct something.
Does the Oneplus 6T support a HDR10 display?
I had the Xiaomi Mi8 Pro and that did.
Looks good on maximum brightness, or very close to it, but anything else looks quite dim.
I must say that the screen is quite dim. I have to keep the phone at 65% or more while indoors to get good visibility from the phone. Not sure what that's about, but highly disappointed.
i found the built in ambient brightness kept setting a little dark and was slow to react to going out into sunlight. switched to velis auto brightness and it is fine now.
thanks for the comments. Was comparing this phone to a couple of others for a blackfriday purchase. Sounds like this one is hard to view outside.

I have zero issues with mine in direct sunlight.
I had to get ElementalX's HBM app to uncover the hidden 40%+ brightness of the screen.

I dont know this app, yet. Does this app work on OnePlus 6T without rooting it?

My apologies I didn't mention it. It has to be rooted
I find the screen itself bright enough. Just the auto brightness is a bit aggressive and can set it too low
But the auto brightness is learning!
It was constantly to low on my phone too. But I dragged it higher every time it was to low. After 1 week of annoying adjusting, it's working fine now!
For those who complains that they have to dial up the brightness slider:
I was like you too, complaining about the auto brightness. However, it has now changed to "adaptive brightness", meaning it learns from your preference. Just turn it on and manually adjust when the auto adjustment doesn't suit you, after a week or two it will get better thanks to machine learning in the system that will learn your preferences.
Also, I remember reading somewhere that the brightness slider now adjusts the brightness in a logarithmic scale instead of linear on older versions of Android.
You can read more about adaptive brightness from an article by Android Authority:
https://www.androidauthority.com/android-pie-adaptive-brightness-927080/
(Also if you are interested, and geeky enough , you can read this excellent article on Android Pie's logarithmic brightness curve here: https://medium.com/@Tunji_D/reverse...ies-logarithmic-brightness-curve-ecd41739d7a2)
The screen brightness is great indoors but not bright enough (even with auto brightness off and on the max setting) for use outside on a sunny day.
Anyone who says otherwise isn't being honest with themselves, with us or possibly both.

Ha! I wondered why I was so much less annoyed with the auto brightness in the last couple of weeks. Thanks for the tip!
Gotta say, have loved the battery life. I like my screen bright and for a while it forced me to behave.

Nothing's fancy with the settings, I think I just made it auto (I believe everything's is by defaults)

Reduced screen brightness when getting hot?

Is the P40 Pro reducing the screen brightness when getting hot in direct sunlight?
My mate 30 Pro seems to do this. Really annoying as i dont have it on auto.
I'm asking because my Note10+ is doing that, my Oneplus 6 never did that and it really sucks for outdoor readability in sunlight...
hey, I know that when outside in the direct sun light auto brightness kicks in and dims it down as it'll help see the screen, other wise you may have the reflection of the sun and then the brightness from the screen, You can always turn it off in settings?
Actually that's not what I meant. On my Note10+ auto brightness kicks in a brightness boost in sunlight, so the display is pretty good to read, but after a while, the device heats up, caused by the sun and then it reaches a threshold and to reduce system temperature, the screen gets dimmed down to a level, where reading any text becomes very hard.

Question Adaptive refresh rate not so adaptive

From what I was reading, the adaptive refresh rate on Samsung phones works as long as the brightness is above 8% or the ambient light sensor reads above 40 lux. Otherwise, it is always stuck at 120Hz.
But that does not seem to be always true. When playing some games, the refresh rate will drop to 60 to match the game. But I also once managed to get the adaptive refresh rate to go down to 24Hz with the lowest possible brightness and with the ambient light sensor reading pretty much zero (I literally went to a closet and it still worked). But I never managed to
So, how is it supposed to work then? Most of the time, mine is stuck at 120Hz, which just eats the battery. I have no idea, who thought that to get less Hz, you need to increase your brightness.

if the game is only displaying at 60fps (which most games will do, at most, unless they have been updated to support 120fps) then there is no point at all in the display showing more than this.

So you've seen the display at 120 HZ 60 HZ and 24 HZ. And you're saying it's not so adaptive. You've just proven that it literally is.

Bruh. My point is that it does not work with low brightness or low ambient light. So yes. It's adaptive up tu some point, but I am at that point where it isn't...

So I guess that showing a static image requires 120Hz then. OK...
My advice, wait for the official release day tomorrow and the day one OTA, which there always is, before we start moaning too much about things not functioning as expected.
I have mine forced to 120hz at all times. Love it, no difference i notice in batt life. Got 8hrs SOT yesterday at 80% brightness. This is on a snappy.

Can the refresh rate be set to 60 hertz / no variations on the small S22 ?
Does this 60 hertz forced limit increase battery life by 20 % or even more ?
