The screen is excellent. It makes it hard to look at my Galaxy Note 3 after using my tablet. Only complaint is the automatic brightness is too dim.
Try the popular app Lux as a replacement.

Thanks! Million times better. I don't know how Samsung can't get it right.

Samsung sux on auto brightness, I leave it the middle
I agree about auto being too dim.
May try Lux.
Its also easy to edit Autobright in a custom ROM too, which I may also do
I just tried Lux and it works great! $4.00 well spent!
Lux is just part of the solution for me. The app has an excellent debug feature to watch the raw sensor data. Using this feature I can see that the sensor data itself has a problem.
Steps to reproduce:
- put tablet in direct sunlight or under a bright lamp
- start the debug readout of the brightness sensor
- cover the sensor by hand (sensor is situated top-right from the G in Samsung)
- observe the reading on the screen: it is something below 10.0 for me
- move the hand away from the screen very slowly but still covering the sensor from direct light: the sensor reading increases gradually to values around 100 to 200. It is easily possible to achieve any value up to here by just varying the position of the hand.
- when the sensor readout reaches a value above 250, I can observe a jump to values above 6000. There is no way to cover the sensor carefully to reach any value in between 250 and 6000. The readout just jumps between these two extremes.
- if you decrease the intensity of the ambient light (e.g. by turning down the sun...) you can achieve values as low as 1000 or 2000. But there is always this huge step bewteen 250 and the higher value.
I oberserved exactly the same behaviour with the stock ROM and with the CM ROM from crpalmer.
If there is a way to change the sensor readout, that would be great. I cannot imagine that it is an inherent property of the physical sensor. If so it is just badly engineered
I'll check out the Lux app, but thought I'd pipe in with my 2 cents (although its probably worth $0.00)...
I noticed sensitivity to shadows with Samsung's auto brightness on my S3 when using an Otterbox Commuter case. If the case cast a little shadow from the lip, the screen would go very dim in bright conditions. My Tab Pro 8.4 seems to have similar sensitivity issues with shadows. I often use the tablet at my desk, with a soft white ceiling light behind me and an overhead desk lamp turned off (unless I am doing paperwork). If the tablet's light sensor catches my shadow from the ceiling light without my overhead light on, the screen goes very dim. If I reposition it with the sensor outside of my shadow, it is perfect for me. It is an annoyance though. Once my Seidio case gets here, I wonder if it will be more of an issue.

Hello all... Is it just me or does anyone else notice a slight screen flicker when not looking directly at the screen? I notice it most when outside, and it is not perceptible when looking directly at the screen... but when I look away my peripheral vision picks it up. Almost like a PWM. Am I alone?

I sometimes see it as well, out of my peripheral vision. It is most obvious when the screen is dim, like when in a darker room with auto turned on. I remember reading some threads about PWM over on the Samsung Galaxy thread that said that this might happen.
Note 2, Note 3, and probably many other AMOLED phones including Note 4 use PWM to dim the display. There should be no PWM at full brightness though.
I think you can use the app Screen Filter for dimming and put the display at full brightness and you shouldn't have PWM that way.

Couple of questions regarding this solution.
1. How accurate are the colors when using this utility? Is it just a filter that is applied to the screen, or does it actually darken the pixels?
2. Does having the brightness set to full impact the battery life when using this app? I mean as PWM is meant to save battery, it must have some impact. Just wondering how much.
I think I remember seeing that even at 100% brightness, there is still some PWM, though not nearly as much as when the brightness is lower.
Thanks.

I noticed it today, I thought it was a problem until I read the comments, yes exactly when I look away or just look at home button I notice screen "flashing" only on cull brightness and light colors, I wanted to bring to service Centre, so is this a problem or not ?
This looks to be a great fone. However, one of the digs I read on many reviews concerns the display brightness both on the high and low end.
Any comments on readability in sunlight, ability to dim in the dark and overall impressions of contrast, color and depth of black will be appreciated.
Unfortunately locked into Big Red until July 10th. No more of that with this fone.
Brightness is OK on the high end. Not the brightest but I haven't had a problem reading display in sunlight - the CABC is very aggressive.
Minimum brightness is a problem because it doesn't get NEARLY dim enough!
Some apps can get brighter than the stock implementation reaches, btw. Though the higher limit isn't too much brighter.
For the automatic birghtness I do feel the auto-brightness levels for the low light and bright lighted areas is incorrectly calibrated.
For night time reading when I want lower brightness than permitted by the phone, I use the application "Screen Filter" from Haxor Industry. It's available on the Google Playstore and is a highly rated app.
For day time viewing when I want a higher brightness, I just turn off auto-brightness control and push the display brightness slider up.
Wish Asus had given us a tool to calibrate this according to our individual preferences. This kind of a tool was available in CyanogenMod, unfortunately not implemented by Asus as yet.
I've not received mine yet so I'm not talking from experience of this phone but I always use lux auto brightness on my devices rather than those that come built in. You then have complete control of its behavior.

I started using Velis Auto Brightness last night and now the display brightness at all times is just perfect. The velis auto brightness tool also allows me to tweak the brightness curve to my individual preference.
The stock brightness solution leaves a lot wanting. The minimum brightness is way way too high.
Try lux app ?
Its brighter than the Moto X 2014 and I think my Nexus 6 ( I haven't compared it yet) however it's still easy to see in direct sunlight for me YMMV
I hope we'll see an increase in max brightness in a future update. Hopefully it's just a matter of pushing a little more voltage to the screen. It's not unusable...but using the phone yesterday in the car, a little bump in brightness would have been welcome.
Auto-brightness is fairly worthless...so investing in Lux and learning it.
Thanks lux is pretty awesome for dimming the screen well try brightness later. Since its super bright and hot day I'll check out brightness with lux on
Visibility is a bit better with lux turned to max

From what I understand, the "Auto" mode goes brighter than the maximum setting allowed when setting brightness manually. Is this correct?
When I use the Tab Pro 8.4 outdoors on a bright Sunny day and use "Auto" it is almost decent... So I put a hood on it to make it even better. But with the hood, the sensor gets screwed up and turns down the brightness. Here is what I mean with putting a hood on:
drone-pilot-zone.com/wp-content/uploads/2015/01/Summitlink-7-Inch-Tablet-iPad-mini-Sun-Hood-Sun-Shade-White-with-Tripod-Mount-for-all-version-iPad-mini-Compatible-with-DJI-Inspire-1-DJI-Phantom-2-Vision-FC40-Transmitter-Mount-0.jpg
Basically, I want to keep the screen at absolute highest possible brightness possible - and put a hood on it as well to make it easier to read.
I'm also interested in hearing recommendations for anti-glare screens. It is impossible to tell what people are selling and what the differences are between different offerings.
I don't know about stock (I once heard that you can't turn it off in stock, but can't confirm), but any of the AOSP-based ROMs can have the brightness ramped up to an eye-blinding value.
I have my brightness fixed at about ~10% of the whole bar because the adjustment is so sensitive it often adjusts to that super brightness and cause pain in the eye...

Rate this thread to express how well you can see the Samsung Galaxy S10+'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!
it's pretty dim, to be honest, i wish we had screen brightness like some of the older motorola phones did when android motorola was still for the cool kids instead of the soccer moms.
Best device ive used in direct sunlight. I work outdoors in the Texas heat and I have no problems seeing the screen.
10/10 for the display, its gorgeous.
Agreed, the brightness when in direct sunlight has much improved over the S9+. It's very usable on a bright sunny day
The display blows the note 9 outdoor usability - Florida sun.

I have S10+ and can't see anything while in my car or outside. The comments above saying it's so great make me think eventhough we have the same phones, that they are talking about a different phone. I think it's awful and now regretting my decision to get this phone because this drives me completely insane. Rating 2.
No problems her in crazy sunlight. Phone does get warm because of the max brightness and direct sunlight but still very clear to read.
Its excellent

It works really well under sunlight and yeah the phone does heat up a bit but it's ok I can see and read well my screen
On max brightness it's bright. Inside it blinds the crap out of me. Outside I can see it pretty well.
Put it on adaptive brightness. I guess there's a limit to how bright we can manually set it versus how bright it gets automatically.. I played around with these settings myself and it does get brighter when you turn on adaptive brightness. Try it! I'm sure you'll like it better! Because I was thinking three same thing you said, house the hell are these people thinking it's great in the sunlight?! Way better with adaptive enabled!

You are CORRECT. This has been from the very start. Only adaptive brightness will give you the max potential of the brightness of s10+'s screen.
For s10+, high brightness mode is entered when sensor reads 40,000lux, and its exited when sensor reads below 8000lux (it used to be 5000lux but it must have been changed at some point). When sun hits the screen, screen is very visible and good. When you are outside but sun isnt on the screen, you can turn your phone towards sun to activate HBM, but it may exit once you turn it back to yourself.(quite annoying as manual max is very limiting at 300nits).
There is a HDR bug, only works on android 10, you can trick the phone to stay at HDR brightness(brightness is still adjustable all the way from 1.6nits to 700), so you can manually adjust it to max brightness(700nits) whenever you want. This is the reason im staying at android 10 lol. Had to downgrade from android 11. If bootloader version turns to 10(currently 9) you wont be able to downgrade(maybe with root you can, i dont know) so its good to consider doing it
Ive always auto brightness turned on,
after installing the UI3.1 , under a bright light, it doesn't go so bright...but under sun light, or in dqy light, its just brighter and its get sooo much better...,
It's like sensors understand where u r

I was on 3.1 for 2 3 months and it enters at 40.000lux just like 3.0, i doubt they increased the thereshold cuz its already too high.

Yeah that puts a lot of wear on the display fast.
Avoid using in direct sunlight or at least limit it to seconds.

Hey all,
I was looking at my phone, the Samsung Galaxy S20 Ultra, and I noticed some kind of ghosting or burn in or something. It looks like the image of icons that were on the screen, and are burned in. Any ideas? I included a pic I hope will explain better.
Running it in sunlight and/or brightness over 50%?
The pixels are wearing out from use. Blues go first, reds last generally from wear.
Use manual brightness control. Avoid use in direct sunlight. Keep brightness no higher than needs. Use dark mode and dark wallpapers.
Rotate widgets and icons.
My homepage and settings tweaked to minimize premature display wear.
Test it and see what you got:
Thanks for the insight. Is there any way to fix what has already happened?
Negative. It's a normal wear thing.
It's possible the manufacturing quality of that display wasn't good. See if you can badger Samsung into a warranty repair or reduced repair price. There have been a lot of issues across the board with variable refresh rate displays. One reason I stayed with the N10+.
Using dark mode and dark wallpapers will make less noticeable.
In the future take steps to prevent this with a new display. Yeah they get very bright but organic LEDs aren't as robust as their thicker non organic counterparts. Limit max or near max brightness to seconds not minutes. Avoid using in sunlight whenever possible. A 50% max limit except for some vids is sensible and helps a lot. Use lower levels in dimmer light, don't burn your retinas or display out.
