Hi everyone, as you should know the Asus Zenwatch 3 has an AMOLED display. From my understanding this should mean when displaying the colour black, the pixels should be turned off completely (like on my S7 Edge).
I was looking at my watch in a pitch black room with an ambient watch face displaying a black background and it appeared slightly reddish. Compared with my LG G Watch R sporting the exact same watch face it was clear the LG had the black pixels turned off but not on my Zenwatch 3.
I've attached a couple of pictures taken with my phone of the Zenwatch 3 in a pitch black room, one with normal shutter speed and the other with a 2 second shutter speed. Evidently the 2 second shutter speed shows that the display is in fact not turning off the pixels. The pics were taken when the watch was charging and in ambient mode with a watch face set to true black only.
Can anyone else confirm that this is the case and maybe a reason why? I'm worried that battery life may be affected by this with always on display enabled.
Lastly on a side note, are the black lines that aren't illuminated something to worry about?
Mine is the same, including a similar set of dark lines. I've seen others on Reddit report identical concerns.

Noticed this too, thought I was crazy lol...kinda waste of an AMOLED screen.
Hmmm ok at least I'm not the only one. Hopefully Asus is able to change it in a future update.
Yeah it is weird, black watch faces aren't truly black. I think they did it so watch faces can blend into the color scheme of the watch, if you notice the color overlay on the app launcher
That's because of auto Brightness. Turn it off. This impacts battery life. I observed this on very first day after the purchase. Using manual Brightness since then.

I just tried disabling Auto Brightness but the red tinge of the black background still exists.

It doesn't happen with me. If I turn off auto Brightness the blacks go complete black. Do you have live display turned on your phones? If so try disabling it. May be this setting depends on your phone. All I can confirm is if I turned auto Brightness off amoled works perfectly.

Not sure what you mean by live display but I just have a stock S7 Edge. I prefer keeping the auto brightness on for my watch so I guess I'll have to live with it.

Live display is when some ROMs allow the screen to have a tint at night time so the blue light from the screen won't affect your eyes at night
Me too have similar display and black line like that.
Glad I'm not the only one with this condition.
I also have those black lines, was about to get a replacement but since I'm not the only one and it doesn't affect overall performance or aesthetics its fine.
Yeah I have also black lines and screen is not completely dark with totally black watch faces
Turning off the auto brightness is not a solution. Its a pain if you had to adjust the brightness all the time
This has always been confusing and I am looking for clarification on the Lock Screen/ Screen dimming, etc.
So I went into the display settings and set it not to turn off for 1 minute. Then I checked the power saving settings just to be sure the screen would not go dim or lock after 5 seconds. That did not work. Then I checked the security settings to see if something was over ridding every other time out setting and I am lost. Either these settings have never really worked since the original note and android/ google is lazy or I am not doing something right.
Dose anyone have a step by step walk through of all the settings that would affect when the screen dimms and when it locks? (Sometimes I am running music through blue tooth and I don't want to the screen to dim for specific applications also. There has to be a setting somewhere because Google Maps does not allow the screen to dim or lock when in nav mode.

I really wish someone would have answered your question. Mainly since I have the same freaking problem.
When the phone app is running, I am constantly getting dimmed, seconds only to do something.
Tonight I was using an app that monitors BBQ temperatures. Always dims to fast. Set the screen timeout for 10 minutes. Still dimmed after 30 seconds or so.
How does this work? I'm not sure the screen timeout setting does anything.
The screen diming feature is part of the auto brightness function and works by using the ambiant light sensor to adjust the brightness of the display. According to the amount of light detected in front of the display.
Screen locking happens when you haven't used your device for a specific amount of time.

It dims before it locks. That's what I was referring to. I think the OP was as well.
I set the display for 10 minute timeout. It dims and locks the screen in less than a minute. I can't figure out how to stop it.
Is that a clearer question?
Well my screen dims for some seconds before going out, but, always as per the time I set , for instance, if I set to go out after 5 mins of inactivity, it dims after 4 mins 55 seconds, then goes out, I dont use autobrightness, and I use entertainment mode
It was secure lock time setting.
It was disregarding the screen timeout.
Hi,
Have had the V40 since release date. Feelings are mixed bag of frustrations.
My screen is constantly dimming and then going bright. Screen brightness is off. Is there anyone else experiencing this? Can anyone help?
I want to add this.... This problem seems to only happen out doors..bright sunny conditions....
Thanks!
I have the same thing, but it's a dimming before the screen goes dark ... it never comes back on brighter unless I touch the screen to keep it active, if I don't touch the screen it soon goes black.
Play with the screen saver settings in display, setting them to different times to see if that's your issue.

I see what you're saying. However that's not what I'm taking about. It's almost like a flicker... Almost like the screen is overheating and the screen is dimming to protect it.......
Have you used or are you using package disabler pro?

I noticed that on my S10e, auto brightness doesnt work as well as it did on my Note 9.
Sometimes I have to manually turn down my brightness if I turn off the lights in my bedroom for example. Or if i turn on the lights, brightness stays on the same level. But if i turn off my phone display then turn it back on, the brightness is suddenly changed.
How well does it work for you guys?

I have noticed that my S10e is slow to respond to ambient lighting
I have an S10 and to be honest it's hard to say if auto brightness is working how it should. Coming from an LG V30 this phone's display is significantly brighter and especially more apparent when using it in the dark. Even the darkest setting is too bright. I always check the level to make sure auto brightness is working as it should and I guess it is? Either that or it's stuck.
my only comment is that in totally dark room it does not go all the way down , it stays a little bit brighter than normal and than my old iphone x
talking about the s10+

yeah same here, and the strange thing is that on my Samsung Note 9 & Samsung S7 it actually used to go all the way down in a totally dark room, but on this phone it doesnt for some reason..
It can take a bit for Adaptive brightness to learn what your favorite settings are like.
Yes, same here, I have s10 and in the dark auto brightness is near to half. Wtf?! I tried to calibrate, no chance. For sure this is a bug. If you go in *#0*# you will see it s writing uncalibrate light sensor

nah, on my Note 9 & S7 it worked as it should on the first day i got those phones
there clearly is a problem with adaptive brightness on the S10, anyone with the S10 who had another samsung phone previously will notice that
no, the auto brightness is trash. it sucks. it never gets bright enough even tho i've made adjustments literally daily. it sucks.

Yup. Same here. Maybe software update will fix this soon.
Even with factory reset it still happened.

Different topic: I will wait for T-Mobile firmware one more day and may possibly return the device back to Samsung and keep my Pixel 2

First reason: I want some T-Mobile features what unlocked doesn't provide natively and may require an extra app to function, but if before return window closes, I would be able to find a 100% firmware that would work, then I may not return the device.
Second reason: I don't like the fingerprint on S10e and maybe it is somehow better than S10's implementation, I still have to be more precise than Pixel 2 and other which had the sensor on the back.

Interesting. I came from OnePlus 6t, the in displayed scanner suck kiwi balls. Everytime you switch screen protector you needed to rescan your finger. Lol.

Oh, that is not convenient at all. I think the manufacturers are pushing their limits to please customers with new designs/features which in reality hurt the quality of the devices we pay for
I have the S10 plus and the auto brightness seems to be functioning fine. Occasionally in the dark I get thrown off with how bright this screen is. The brightness setting does decrease significantly in the dark but when viewing something with a mostly white background, I have to squint until my pupils constrict to a point where my retinas aren't getting torched. In brighter environments, the brightness level seems to increase accordingly.
Hi guys,
I came across an article about this issue from Aman Jain (Valuetalk) : https://www.valuewalk.com/2019/04/galaxy-s10-auto-brightness-no-issue/amp/
Facing Issues With Galaxy S10 Auto Brightness? Do This

Galaxy S10 auto brightness

We have already covered the issues with the proximity sensor in the Samsung Galaxy S10. Now, it appears, one more sensor in the Galaxy S10 is not working as it should. Several users are complaining that the Galaxy S10 auto brightness or the ambient light sensor is not working perfectly.
Galaxy S10 auto brightness – what’s the issue?
Affected users have raised the issue on social platforms and Samsung’s product forums (first spotted by tech site PiunikaWeb). Users complained that the brightness level does not automatically come down in low light. So, they have had to do it manually, but it remains at the set level even when the light is good.
“Sometimes I have to manually turn down my brightness if I turn off the lights in my bedroom for example. Or if i turn on the lights, brightness stays on the same level. But if i turn off my phone display then turn it back on, the brightness is suddenly changed,” one user said.
Further, users also say that with adaptive brightness turned on, the screen goes dark when facing the sun. “White highlights are bright blue, and all colors are distorted. It’s unusable. Spin back around or go into the shade, and the screen comes back to normal,” one user said on Reddit.
Users say that this was not the case with the Galaxy S9, where the auto brightness feature worked perfectly. One user even claims that the Galaxy S10 doesn’t even have a light sensor, instead, maybe there is some in-display sensor that needs a software fix.
“..even if you put your finger on the front camera the auto brightness still moves …..also if you acces this *#0*# you cannot find the light sensor because it’s not there like old samsung phones,” one user said on Samsung’s product forum.
Adaptive brightness to blame
Several users believe that the adaptive brightness is to blame here, and so they have turned it off. However, turning it off is not a solution, and many users agree to that.
“This is a huge problem, and should not be happening on a new phone. The adaptive brightness is a major feature of the phone, and simply turning it off isn’t an option as far as I’m concerned,” one Reddit user said.
It must be noted that Adaptive Brightness came with Android 9. It is an AI based feature that gets better with time. Meaning, it would learn from the interactions that users make with the screen brightness slider, and over time, it would customize the brightness automatically to meet the users’ needs.
Google says that in its testing for Adaptive Brightness, it found that half the test users made fewer adjustments to the slider after a week of using the Adaptive Brightness.
Not an issue, give it some time
Based on Google’s explanation, it seems, users need to give some more time for their phones to adapt to the Adaptive Brightness. Even Samsung’s explanation of the issue with the Galaxy S10 auto brightness is somewhat similar.
“From Android P, a user’s brightness setting pattern is learned, and when the user sets a specific brightness the automatic brightness is controlled to be closer to that specific brightness…… However, when you set the brightness, the brightness can be applied immediately in the short term. If more than 30 seconds after the screen is turned off and the ambient light environment changes by more than 60%, this short term setting brightness will return to the light that was relearned,” Samsung developers say.
Additionally, developers say that users can reset the brightness curve to start the learning process again. To do this, go to Settings – Apps – Show system apps – Device Health Service – Storage – Manage Storage – reset Adaptive Brightness.
All this explanation from Samsung developers and Google could mean that the complaints from users about the Galaxy S10 auto brightness are valid, but it still is not an issue. Things will get better with time as AI learns more about users’ preferences.
Though it is not a bug, affected users do not seem very satisfied as they still have to live with inferior quality images (even if for some time until AI applies the learning).
“Not sure it’s a error to be replicated per se. It’s just an inferior looking quality of image. They will have to make the comparison to see the very obvious difference,” one user said.

FYI : the brightness sensor is under the screen like the proxity sensor, located bellow the wifi / network icon. It's visible at sun light.

There are actually two light sensors: front and back of the phone.
Unlock the device without pressing the power button and only by placing your fingerprint on the sensor.
The light sensor starts checking the environment light only in this situation
If I keep the brightness to the Maximum, I notice that in bright sunlight/extremely bright indoors, the screen gets Automatically even brighter and dims when the phone notices the environment is not that bright !!!!
You can experiment by shinning a flash on the top right side of the phone with slider on max brightness.
Isnt it stupid – When the user have disabled auto brightness or any power saving modes the phone keeps getting bright and dark
I cant believe Samsung has let it pass this to the production models…
@craige
I think it is intended as you see there's a color RED at the far end of the brightness scale, and that's signifies the most extreme situation the screen can go, which in prolonged use may damage he display. But still, it can provide a elevated readability when you are out under sunlight... And return to safe margins so as to prolong the life of the display...
