Root and display brightness - Samsung Galaxy S9+ Questions & Answers

I was always curious about this. Is there a way to force the device, at will, to use the automatic high dynamic brightness?
I’m not complaining about the brightness of Samsung panels, but the one thing I never could get adjusted with is how whites with APL that’s over 80% look; they’re under 400 cm/nits of brightness on the maximum manual brightness settings. The iPhone X’s OLED display doesn’t have this issue, achieving over 620 cm/nits on max manual brightness.
With the automatic brightness boost from high ambient lighting, the high APL whites being displayed on the S9 match that figure over the iPhone X. Is there a root or at least a theoretical method to get that brightness setting at all, rather than under situational conditions?

I don't know to be honest, but even the Galaxy S6 back then had that boost, so maybe you should search for a method for the s6 / s7 / s8 first to be sure it is possible.

SGS2 lowest brightness setting too dark

I just bought a white SGS2 today for my wife. When I placed her SGS2 side by side with mine, I noticed that the brightness level is at least 2 step below mine. Eg, at the lowest level, hers is very much darker than my SGS2 set to the lowest level.
As a result, I cannot set the brightness to auto as it makes it very difficult to read in low light conditions when it sets to the lowest level, ie it is too dark.
Anyone with the same problem? Or anyone knows if I can change the brightness scale to be brighter?
Edit: Forgot to say that both SGS2 are running on the same ROM and kernel as per my signature.

Nokia Lumia 800 bug when you adjust Brightness

Hi , i found a bug on Nokia Lumia 800 BrightnessSetuo.
If you diseablle Automatic Brightness, and put it manual on medium or high, the three touch Buttons dont have light, only when Brigthnes is on Automatic or on Low (manaal) wrok.
I hope nokia fix these bug soon.

This is not a bug this is a fix given by nokia to increase battery performance.
I also thought it was a bug but checked the nokia forums and in the change log of the latest update it is mentioned that the bottol capacitive button keys only light up if you have ur brightness set to low or auto
My believe is that is is by design. If you're in a place dim enough to struggle to see the capacitive keys, you'll not be using med or high brightness as it will blind you.
Likewise, when you're outside and needing a higher brightness, the ambient light will easily be enough to see the capacitive keys.
I almost always have brightness on low so this change doesn't really affect me. Medium brightness hurts my eyes in darker environment. The only time I crank it up to medium is when I'm outside. Sometimes I'm even on low outside if it's not too light. I never think I will use the highest brightness setting.

blah blah blah....sorry, but you are not representative for 99% of all users. Nice for YOU that YOU prefer low brightness. But most of us users like at least medium brightness in darker areas because the AMOLED contrast and colours are bad and washed out when in low brightness mode. I want to decide myself if i have the button lights on/off with medium or bright display settings.
Finally this "update" is a reason for me not to buy the lumia 800...shame on nokia!

Neither are you.
Did I say you have to use what I use? No. I simply stated my personal preference. No need to jump all over me. Calm down.
Have you guys tried Auto brightness?
It goes all the way to minimum brightness if you use the phone in the dark.
The bottom buttons are lit up too.
I tried out the auto brightness for the first time today. Seems to work well. It places itself in between low/mid brightness in an ordinary lit room which is fine for me. And as you say the bottom buttons are always lit even if the brightness goes up to full strenght.
Think I'm gonna use auto brightness a bit more and see if it behaves good at all times.

[Q] Sunlight readability?

Hi! I'll be using an android tablet as an instrument display in my truck, so I'm concerned about readability in sunlight. How is this tablet compared to other Android tablets? Has anyone compared it directly to the Samsung Tab S 10.5? I've read in some reviews that max brightness can only be achieved in "auto brightness", they claim manual adjustment limits brightness. Any experience with that? Also, do third party auto brightness apps manage to activate full brightness?
Thanks!

I used it already in full sunlight. It's great! Its really useable. The glossy surface is a disadvantage but it's not a problem. I'm planning to add a anti-glare screen protector but it's not a must have if you want to use it outside.
My Tablet Z was already useable outdoors but the Z4 is way better.
I cannot see any difference in max brightness between auto and manual brightness setting (28.0.A.6.8). Fortunately it's going up to max level even on auto brightness. Sadly not every manufacturer is able to "implement" this...
Thanks!
I'm hoping to hear a sunlight comparison between this and the Samsung Tab S 10.5 too!

Minimum brightness

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 LG G6's display minimum dimness. A higher rating indicates that the display can get extremely dim, ideal for reading in very dark environments.
Then, drop a comment if you have anything to add!
It could be a tad darker, but if you use the "Comfort view" setting in notification menu, you can turn down blue light which works just as well. This setting is highly customizable.
To me, this is the weak point of the screen. It will get acceptably dim, though, if you activate both battery saver and comfort view, but who wants to go through those steps each time you want to read at night? I've just been using one of the night shift apps to dim the screen during night hours.
Anyone notice the auto brightness toggle not sticking? AT&T model.

Thanks for the tip, this combo does make the screen acceptably dark enough.
Has anyone had any luck with automating lg's settings? I have not been successful with Tasker and would really like to schedule this based on time and ambient light sensor.

min brightness could be darker.
max should be brighter

I personally didn't think the yellow tint that Comfort View offers helped me. Instead, I used System UI tuner (This app: https://play.google.com/store/apps/details?id=com.zacharee1.systemuituner&hl=en) to enable the stock android night mode. If you want to try it, it essentially works the same but the tint is more red-ish and is more tolerable in my opinion. However, the intensity of the tint can't be adjusted.
Anyways, I do agree with you that the display should get a bit darker.
Coming from a GS4, the minimum brightness is amazing, especially if you use it combined with the battery saver option, it never seemed too bright, whilst on my S4, i often used the screen filter app to lower minimum brightness

Outdoor visibility (max brightness)

Rate this thread to express how well you can see the Samsung Galaxy Note 9'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.
Then, drop a comment if you have anything to add!
Most Samsungs over the last few years have been up over 800 lumens for me, but this doesn't quite reach 600. It surprises me as it seems very bright. Does anyone else measure the lumens?
Is it brighter than note 8?
Not as bright as my N8. The auto brightness is broken, I think.
My autobrightness works well on my note 9. I don't see much difference in max brightness when in auto mode outside between the Note 9 and note 8 though. When not using autobrightness, having both phones at max, the Note 9 is slightly brighter and slightly whiter IMO.
FWIW, displaymate has rated the Note 9 brightest, most accurate, best display ever. Just like they did with the Note 8 last year, S9 this spring.... Sammy always makes the best displays, and currently the Note 9 has the best display available on any phone.

Nope. I think it's a software bug, when toggling between camera and phone sometimes the phone brightness will be brighter than before.

I think when its in manual mode, you dont get access to the full range of brightness, only after putting it into autobrightness mode. Perhaps Samsungs way of not letting the phone get too hot and igniting like the Note 7?

Its normal, all phone manufacturers do that.
This is because an automatic brightness will be able to increase brightness if it is needed for a short time (like when you are outside in the sun and use it for a few minutes) but it wears out the battery and screen so it needs to cut back after a little while. when you are on manual, the phone cannot regulate so the maximum they can allow has to be a safe level. Most phones also dim brightness when you play a graphics heavy game since temperature is death for your battery. its like thermothrottling for CPU. Totally normal and necessary. otherwise people would complain why their battery capacity is down to 70% after 6 months.
Good visibility but i prefer to have the full control of the max brightness without auto mode
