Hello, 3 days ago I bought oppo x3 pro. Phone is awesome, but auto brightness works very bad... It keep decreasing screen brightness to very low level.
I never seen something like that, Samsung S20 works much better, well, even realme x50 works normal. To use phone I had to disable auto brightness. Is there anything like adaptive screen brightness, I read somewhere that samsung by the time learn my preferences, and keep good brightness. Tired this with oppo for 3 days, but seems it doesn't have that option.

If it is the same mechanism as in OnePlus (not sure about it) - then the phone will "learn" after you manually set the brightness to proper level. Give it 2 weeks.
Btw. Rydzyk in avatar, hope youre not the real one

I was teaching for 3 days, but without success. Will try for a week now

Try clearing system cache and data in the relevant apks.
Test the light level sensor to see if it falls within an acceptable range.
I use manual brightness control almost always; doing so saves battery, retinas and sanity.
It also reminds you when it's too bright and your frying your display.
Same here. Helped me out with Lux Brightness and set the minimum brightness to 30. Works fine for me.
To me in Realme 8 it seems to have learn a minimum value for auto brightness instantly, I just set a minimum a little above of the default level (It was very low), and the phone remember that level onwards
well, mine surely isn't 'learning', it keeps defaulting to the lowest value, which is waaay to low.
Are there any alternatives to Lux Brightness that you know off?

What happens to me is that the default auto brightness deactivates itself when it wants, and reactivates also when it wants, very annoying. So I deactivated manually the auto brightness and tried Velis Auto Brightness, this app is a little complicated but works quite well, just you have first to understand the app itself and then tweak a little to your convenience. It has a little bug in Android 11, the notification of lux and % of brightness screen disappears after some time but doesn't affect the app itself. Take a look https://play.google.com/store/apps/details?id=com.velis.auto.brightness

Hello everyone
I just got the Samsung I9000 Galaxy S yesterday and my worst nightmare has come true. I have sensitive eyes and keep brightness on all my equipment at the lowest level. I had asked someone before buying this phone and he told that it is manageable but now I find out that the screen is way toooo bright even at the lowest setting!
It strains the eyes + drains the battery.
Suppose we are not connected to internet through any source. Then if we refresh any widget we get the error "Please check your network access" and the screen goes dull in background. Now thats the perfect setting I would like for the phone.
Any idea how we can reduce the brightness even further through Mod or through factory settings or somehow?
I would really appreciate any help on this one.
Regards.

Bright on 35% level is correct.

Try fiddling with your phone in the morning, just as you've woken up. It works as a nice wake upper though. .
Android default min brightness is 8% (even though it reads 0%).
Two apps that give you less than 8%, both goes to 0% :
- Brightness Level by CurveFish
- Dimmer (Night Mode) by geekyouup
Also, look into changing your background color to black, it'll save you battery and be easier on your eyes. Lastly, the browser has its own brightness setting, found by hitting menu > settings.
Alternatively, only use under direct sunlight.

Thanks. I would try the dimmer and see if 0% helps somewhat though I have read that its only marginally better.
I am hoping that there should be a way to reduce it somehow since it gets reduced when we see some error just like I mentioned in 1st post.
I agree even at the lowest level its way to bright.
I have the curvefish brightness app, but even set to 0 its too bright for use in the darkness.

I've actually written that it's only a marginal improvement, but I omitted that opinion here since I think my opinion is less applicable to someone with sensitive eyes. You might perceive a 3x decrease than what I did, not sure if that'd still be enough.
Again, I think changing to a dark background will get you more mileage, if you haven't already done so.

Currently I am using a relatively black background but when surfing most webpages have white background and that really is painful! I guess I may have to look for some tinted screen protector!
i know this may sound strange, but If I wear my sunglasses at night while browsing it works quite well
You can also use tasker for lower brightness levels..

I am currently using "Dimmer". It takes the brightness levels from 30% (Though in settings it show minimum only) to 10%. I have also tried "Quick settings" so I guess tasker would perform the same function.
When we have locked our screen and we have to unlock we have to slide the screen. When we do that it seems like we have to slide a transparent layer of glass which is quite dark.
Now I am no developer but is it technically possible to create an app which is like a layer of tinted glass on screen so that it dims the screen further?
Regards
I haven't tried the dimmer apps yet but I DO agree that I miss my iPhone which can be set to a much lower brightness level for better privacy, night vision, "before sleep reading".
but I think it has something to do with the display technology. The OLED for Samsung may not permit such low levels or so. I am not sure...

At first even I thought that and I was worried about that. But there are some times for example when you get some error on the screen the major part of screen goes quite dull so it is indeed possible to do that technically I guess just that it cant be done through brightness.
I am baffled why did the Samsung/Android guys set lower level of brightness as option also. It would have cost them nothing and would have saved us a lot of strain and battery life.
PS: Is this the issue with Android or Samsung?
To someone with a bit more knowledge: how hard would this be to do something about? We all know the screen dims to a level that's not for the moment available to manually set some time before it shuts off, so it's got to be a way.
The screen is just too bright for me at the lowest setting - meaning it hurts me eyes (some pity here Samsung) and consuming a lot more battery than it needs to.
+1 for the app that will do this
got me new galaxy s for a couple of weeks now.. but really miss my old htc hd... the minimum backlight setting was awesome for nighttime reading/browsing.
switching on the sammy in bed in the week hours of the night makes my eyes burn! hehe.
an app to force lower or add a filter over the entire screen would be awesome!
samsung galaxy s has a SUPER AMOLED display which is why its bright even at lowest level.

Well I dont know for sure. The device has been working same since the 1st day. I guess its just that the brightness is too much for me. As far as the screen is concerned I didnt notice anything significant but any easy way to check about the problem?
Regards.
Hi, I have noticed the pink tint to the screen when using adaptive brightness below 30-40% and was wondering if it effects all devices.
I have read a lot of people talking about it and that it happens because the screen goes so dark and some people are saying that it is supposed to happen. Is this true and if not is it effecting all devices?
I am on my 3rd device now the first one i took back after a few hours as the screen was tinted really yellow and uneven and my second one had image retention pretty bad and would happen after 5 seconds of the nav bar being displayed and i dont know if it effected them as i didnt try adaptive brightness as i didn't ha e them for long enough.
The one thing i find really weird though is that i have been using the lux app to test if it was to do with the phone going so dim and while there is a slight pink tint when putting the brightness down on the lux app it is no where near as bad as when adaptive brightness is being used and the lux app goes a lot darker.
Thanks.
I've seen all does it specially at night. I consider this is normal
Its because you're brightness is below 0. If you use adaptive brightness at night its lower than 0 without adaptive brightness. You will see the same thing if you use the lux brightness app.
Edit: I noticed you used the lux app, you're correct its not as bad with it, but it's still there. I could be a software implementation or a bug for all we know.
So it is actually on all devices and not a select few?
I got 7 days to return it for another one but if it is on all devices and there is nothing that can fix it i dont think there is no point in risking it for another nexus 6 that could have a worse screen like uneven colours.

This is more of a feature than a defect, frankly...
Not that it is pink, but that it can be dropped down as low as it can.
Basically, there is a minimum brightness threshold. The lower the brightness, the less power it consumes. If you set the brightness below a certain point, the colors (because of the nature of the amoled) will start to mess up a bit. Most vendors will set the minimum brightness high enough to not have this happen. Google sets it a bit lower to save a bit more power, without making the colors go *entirely* crazy by setting it WAY too low.
Its made like that to conserve power. All nexus 6 are like that
I thought it was a defect too until I started researching and like someone suggested turned off adaptive brightness which made the tint go away completely even at lowest brightness setting.

Adaptive brightness is actually a really nice feature.
If the pink bugs you too much, you can (if you know your way around a compiler, that is...) bump up the minimum a little.
What if adaptive brightness is off, and the brightness is set to at least 70%, and the pink tint crap still happens? kernel issue? nougat issue? Because it's very annoying, randomly happens to me. usually, going into twrp and clearing cache fixes it. sometimes it doesn't though.
Help.
EDIT
Never mind. I figured it out. it was night mode that was causing the pink tint via purenexus settings.
title says it all, why is this hidden and can only be accessed thru settings, and it's not a one time toggle, you'd have to go into settings every time you pull your phone out. just why? would be great for the brightness slider to just go to max instead. anyone know if theres any mods for this? or just what this is about, seems strange.

Mine always stays where ever put the slider. But then, I have auto brightness off.
Yeah what version you got? Wish we had outside mode.

Because it's samsung. They will probably never make a good software. Just search for "automatic brightness bug". They just ignored this problem. No wonder they just hidding that option.
Outdoor mode can be enabled by editing something in system folder. Most of custom firmwares provides that function.
I've never seen that setting on mine. It's automatic for me.

IT is not a bug, and yes, there are ways to increase brightness beyond standard maximum, I remember from the days of my note 3, that many people posted very bad screen burn in and excesive batt drain when changing the lines to attain the most bright screen possible, same applies to speakers, might as well get blown, The auto brightness in note 8, in fact is very well implemented, because it learns your preferences, that is, if set to auto, and you move the slider, whenever the phone detects the same lux level, it will set the level you chose, infact, when in autobrightness, when sensing too much light, it will set an extra ammount of brightness

Agreed. Works very well. Was using GPS Google maps for the first time yesterday, screen was automatically too bright. I used slider to lower brightness, it learned my preference.

Since long I haven't seen any Note device (at least International versions) have Outdoor mode enabled by default unless you are using custom ROM. But this mode i have seen available on low range samsung devices. Actually it is hidden and one minor change in settings app enough to enable outdoor mode.
I will try to make small app without making changes in setting app, though it might needed root access.
Thank you dr ketan! I have used your excellent roms and kernels in my note 3 and 4

hey something cool came out of this post, awesome!
so the app acts like a toggle to turn on the outdoor mode, pretty cool!
Works perfectly. Thank you.
Have noticed this mod seems to time out after 15 minutes or so. Any workaround for this?

I think it's just not possible to manually set highest brightness of display in Android 9. But is there any way how to set it via some app or edit something?
I know there is toggle for adaptive brightness, but setting it for full brightness will just make display cca 70% of possible brightness. The 100% brightness is on only when sunlight comes to the light sensor. When I use Note9 for flying DJI drone on sunlight, I want to have 100% display brightness for that 10 minutes of flight. It's just sooo annoying that I have to use separate flashlight - shining to the Note9 sensor to have full brightness on sunny day in shadow. Otherwise, just manually set brightness is not enough for flying and reflections are stronger than display...
Thanks for ideas!
jd14771 said:
Really easy fix..
- pull down notifications
-expand all notifications
-expand brightness settings by hitting the downward facing arrow (brightness settings)
- select "show brightness settings on top"
Now you can bump up your display brightness for those 10 minutes. It would be absurd to spend any more time on an app selection

Thanks, but I can say I'm kind of poweruser So again - When you set brightness manually all the way up, it's just 70% of possible brightness. It still uses light sensor to detect light and if you face the sensor (still manually on full) towards the sun, ONLY THAN you'll get 100% of hardware brightness.
Haha, okay... Maybe somebody else with Note9 and experience with Samsung's "outdoor display mode" may know. Anyway, see the attached image, maybe you get that point from other user...
I've use to do it on my Note 2 this way, I don't know if it will be any help. I know what you mean, the extra brightness is there, you just want to be able to switch it manually.

There are a number of apps in the 'Playstore' that purport to do what you want.
The one that I use is called 'High Brightness Mode', it's a free app and enables you to place a widget that can be used to manually crank up the brightness to beyond the 100% shown by the brightness indicator,.
According to the instructions, it goes a lot higher if your device is 'rooted', but nonetheless works on 'unrooted devices too.
It seems rooting is the only way how ti get 100% brightness...

jd14771 said:
could have just tried turning on adaptive brightness. from what i read outdoor mode wont trigger unless you are on adaptive brightness at exactly 100% brightness.
if i had to guess its because the max brightness in the sun causes display burn in- so to limit the issue they only allow adaptive brightness to go past the 75% software max
Click to expand...
Click to collapse
Yes, but as the OP was trying to point out, the software absolute max is actually about 15-20% below the hardware absolute max capability.
This can be enabled by tweaking the sys file related to brightness, to rewrite the specific line, you need to be 'rooted'.
jd14771 said:
I have yet to see you provide instructions on how to do that.
regardless you dont need to be rooted to get the extra brightness, conditions have to be met in order to save the screen from burn in abuse. There are tons of people reporting burn in from the outdoor mode. it only make sense that only adaptive brightness can take the screen into danger territory, probably has safegaurds built in to avoid damage to this $1000 phone. so far ive provided more insight than anyone.
Beggars can't be choosers.

Once 'rooted' there are a number of 'Magisk/Xposed' modules that can be installed to push the brightness beyond what's available by default.
Did you want me to detail the 'rooting' and install process?
If you do a quick 'Google' you'll find a number of threads on 'XDA', 'Reddit' etc, going back a number of years which are the focus of the OP's issue.

The brightness slider full to the right, regardless of the adaptive brightness setting is as bright as the phone gets.
How do I know this? Because e-ticket apps such as Ticketmaster and mobile payment apps like Samsung Pay go full brightness when showing barcodes, and there is no difference between manually set 100% brightness and 100% brightness when set by Ticketmaster and Samsung Pay.

incorrect, the sun brightness method as well as youtube and the photos app does go brighter than the screen is normally i have max brightness past the line adaptive brightness off performance mode turned on with brightness set to 10+ specifically which boosts the brightness past the normal brightness as well as vivid mode but still not the same as the brightness you get in youtube apps or on the photos app, the xperia 1 and xperia 5 does this too and i thought it was specific to them.

Hi i am on gloabal stable rom and i have noticed that the brightness in low light goes to low and iff you change it manually to slightly higher it wont stick and after the phone screen is turned off and then back on the brightness in darker areas is to low again. Most android phones on Pie i have had have adaptive brightness meaning it will adapt to how you set it in each environment but on Miui i think it is different and it is also called auto brightness rather than ambient brightness. I am rooted and i have tried a couple of magisk fixes but nothing changed and in dark area it is still to dark and this is a big annoyance for me and i think it should an easy fix. Maybe someone know where the brightness values are located and can explain how to change this manually so it does not go so low in dark areas.
I have the same problem with 10.3.1 mi 9t pro
I don't have the problem anymore I moved to lineage

Somebody on forum said that you have to train your adaptive brightness. Every time it is too low you bring it up with slider and after few times it should learn your preferences. I didn't yet try this, but I will...
Usually on Android it works like that but on miui its called auto brightness rather than adaptive brightness and didn't work in the same way.
Any news on this? Does it work on MIUI 11 / Android 10 better? I love this phone but this issue is really annoying.
I'm on miui 11 EU it works perfectly.
