DC dimming? - Samsung Galaxy Note 20 Ultra Questions & Answers

Hi. I like the phone on paper, but looking at this screen makes me want to rip my eyeballs out almost instantly.
So I wonder if there's a custom kernel\rom with DC dimming functionality. That's pretty much my biggest problem with it. Even Xiaomi fixed that lol.
PS lol wtf its pulsating at 100% brightness? There's a good trick to reduce flicker at a cost of screen life but it won't work with screen pulsating at 100% brightness.

Who Uses Auto Brightness?

Who here uses the auto brightness on the captivate? I noticed that when i have it checked off, it makes the screen dimmer than it used to be. When the screen is dimmed too far, i realized that we're not taking advantage of the super amoled. The colors just look average when the screen is dark. I checked the auto brightness off and the difference is night and day. I have the brightness around 40 percent. my only question is, will my battery take a HUGE hit from this?
btw, what exactly is power saving mode? i originally thought it was the same as the auto brightness but im guessing im wrong.
I don't use auto brightness on mine. I usually keep it all the way dim and my batter lasts wonderfully long. And when Im trying to look at something that i think needs to be brighter i just slide my finger across the notification bar to the right. To me power saving mode i think just adjusts the brightness based on the colors of the image it is displaying. I've had it on since I've had the device though so i don't know exactly how it works.

I keep mine on the dimmest setting since it still looks great, and even downloaded the screen dimmer app recently. I've never used anything higher though... I take public transit and actually feel conscious about how insanely bright and vibrant the screen can be to people near me and never turn it up.
When I'm outdoors during daylight hours, the only way to discern anything on the display is at full bright. Yes, there is a big hit on the battery. I get about 4 hours, but I have a spare battery at the ready.

Why I hate the screen brightness on this phone

So I made this thread in the international forum by mistake so I figured id just make a separate one in the US forum
"So I have this phone on VZW and I love it. Recently I just got bored one day and decided to just crank up the phone to full brightness just to see what it was like....for the love of God my eyes had a mini orgasim!. It looks amazing! Now the reason I hate this is because I know full brightness is a huge battery killer and plus will drastically increase my chances on having a burn in =/ im so use to having my 4 hour screen time yet i know if i keep my phone like this my battery wil tank big time =/"
So I guess my main question is, is there currently anyone that runs their phone on full brightness? If so what kind of battery time are you getting on average along with screen on time?

I had 32% on 11hrs 38min off battery and 2hrs 56min of screen time before i put it back on the charger (work from home) but thats the best I've gotten. I hate auto brightness and always run at full.

I use a brightness widget and keep it at 25% most of the time. Lasts almost all day if I am not playing games.
Outside and when showing it off 100%.
At night (when the wife is sleeping) 0% is too bright. That's my only complaint.

Download screen filter from the market. Complaint gone
Played with the SGS3 in the Verizon store...I used the settings app to turn the brightness up to Max and compared to my nexus..I noticed the nexus was brighter? Can anyone else confirm this?

I don't know how you can stand looking at the screen on full brightness. For me, even back to my Fascinate, the SAMOLED(+)(HD) screens have been painfully bright (I get haloing on the white areas in particular) at 100%.
Also: SAMOLED(+)(HD) screens are artificially limited to 200nits to preserve the tiny little LEDs that make up the screen. They're actually capable of MUCH brighter, but that drastically reduces their lifetime/consistency.

i made a tasker task, that chages brightness to my needs.
typically if im plugged in (AC or USB) its full bright & never turns off....great stuff
You must have a setting or something else going on, since it is plenty bright even at 50% and silly bright at 100%.
The first demo at a local VZW had a brightness issue as well, but they corrected it, or replaced it. Can't remember. Even at 100%, it was too dim.

I don't ever remember reading anything about "tiny little LEDs" in my research of AMOLED technology. It is exactly what the name states, an "Active Matrix" of "Organic" compounds that respond to electrical impulses by emitting light. Sorry if I'm coming off like a **ck, not trying to, just sayin...

I'm not sure what point you're trying to make. At what point is one element of an AMOLED screen NOT a "tiny little LED"? If you want to argue that we're not looking at discrete LEDs like you would find blinking away on the front of your computer, or even the indicator LED on the S3 and GNex, then yes, but you're pushing semantics much farther than the original point of my post, which was to note that the screen is kept at a maximum brightness that is much lower than the capabilities of the elements that make up the screen.

Battery life horrible? Try this!!

For all you guys who need the edge on battery, and dont need alot of screen brightness, like me, then try out this app on the play store called screen filter. (I am not affiliated with this in any way, I just like the way it works). What it does is apply a "film" over your screen going even lower than android screen brightness. Perfect for office setting (like me), at night when brightness is too much (laying in bed playing a game), or where bright lights might not be wanted (movie theater, work, etc...). I personally love it, I use it usually at 75% with the android brightness off, and everything is still visible, just that extra kick of brightness is gone. Sometimes I go down to 50%, but that gets me seeing my reflection just as well as the screen itself...
It also helps to keep out them creepers that try to look at your screen while sending private texts, pics, etc... Helps keep wandering eyes off of the fancy 4.8 super AMOLED display!
You can add widgets to custom brightness settings to suit yourself, I have 4 right on one of my screens that I use frequently!
I recommend this app to anyone and everyone!
It wont let me post links, but if you search "screen filter" it should be the first app. The logo has a white rectangle outlined in orange with a grey circle in the corner. Not too hard to find at all.
I'm almost positive that screen filter won't increase battery life. I think the phone basically "thinks" its still at a higher brightness than what you see, so it really doesn't improve battery life. I may be wrong though but I remember seeing that when I used it on my droid x.

OLED pixels produce their own light (that is, without a separate backlight). Colors are made darker by dimming pixels. If the app makes what's being displayed on the screen darker, it should be helping battery life. The same reasoning applies to saving juice with dark backgrounds and inverted apps. It just only works on OLED screens and not backlit screen types.
Okay. I wasn't sure if I remembered correctly. Thanks!

Lux Auto Brightness works a little better, in my opinion. It can go less than the screen's brightness without the filter look.
Hi guys,
A friends uses auto brightness, and only speaks ~ 20 minutes / day. A few browsing, reading e-mails, games, just got him at 2 days of usage. Not bad in my oppinion, but certainly they should have improved the battery.
To me it seems like the battery life is longer. My first week of use around 9 or so it would be in the red, but using it throughout the day, at 9 tonight it sits at 37%. Yes it will vary depending on use, but mine has been on battery 15h 30m and screen is only 18%. Cell standby is 30%, and chrome and facebook are each 11%. Everything else is quite small compared to those main apps used.
It seems to me it is helping, but it may not idk. I will continue to use it unless I run into a major issue with it.

+1 to Lux. Set your own brightness levels for various light levels. It can make the brightness very low, almost not visible.

I would be happy to get 2 days of usage... I probably could get 1 and a quarter, but I charge mine every night to be safe. Really varies on how much I use it during the day. Some nights I plug it in with 10% others with 50%... I know its not the best for the battery, but I just plan on getting a new one when this one takes a crap. I have a feeling this phone will be around long enough that the option will still be available

What I would like is for my battery to last just *ONE* day. It doesn't do that. I don't mind charging it every night, but I'd prefer it last the day without me having to either charge it or switch batteries.

nice find on this. i use inverted apps, and i like the way this works

Is my S6 faulty?

Hi all,
Started using the phone just 2 days ago and noticed some issues. The main one is the phone dies over night. I have nearly 40% battery then I can't turn the phone on the next day. When I plug the charger in it goes up from 0%. I then turn the phone on when it reaches around 15% and to my surprise the switched on phone days 58% battery!
This happened two nights in a row now
Other things I've noticed :
- some camera noise while on the screen which takes the photo. Is that normal? The resulting images aren't blowing me away either.
- screen tint on white background. This is my first amoled and my eyes are finding it hard to adjust. I heard this is normal? Mine is a bit yellow all over and greenish at the bottom. Should I be worried?
- some lag on chrome. This is mainly pages with ads maybe I need an ad blocker. Can someone with an ad blocker confirm that it speeds up the browser.

There's something wrong with your battery's calibration. Considering you've only had the phone for two days, I'd switch it out for another unit if you can.
I was going to try a factory reset but if the battery stats are out of sync then do you think it's a hardware problem?
Hi all
Fixed the battery by doing a factory reset.
I'm still getting camera noise aka pixelation when taking photos in low light. My photos don't look anywhere as good as others.
Also my headphone jack is stiff I have to use a lot of force to get my headphones in.
My whites are more greenish than white with a bit of pink at the top.
Are these things normal or should I get it swapped?
Anyone??? Waiting before I go return it.
Seems chrome lag is normal, it's not well adjusted for the s6, I use the stock browser it works well, plus it has that cool finger print feature to log into websites.

everything else is normal battery was abnormal but u fixed it on moled whites look slight yellowish but if its too much and the pink tint issue i m not sure take it to service centre!
Thanks all. Took it to my retailer who said nothing is wrong. I also saw a display unit which looked worse on the tinting. I might just need to adjust to this display first time I've used an amoled. The headphone jack is loosening up and the camera looks really good in daylight so guess it's just not great with low light.
I need to do some research on rooting now to get the best out of this phone!
You need to let the battery calibrate for a few days.
Display wise, changing the brightness affects the tint of the display. You'll notice less pinkishness on a higher brightness setting.
You can try change your screen mode too depending on whether you like saturated or more natural colours.
I don't like having the display too bright it will hurt my eyes. There's a bit of pink tint at the top in the middle I'm going to try and get used to it.
I did find this app called screen balance which has reduced the yellowness of my screen! I've also installed adaway and now have no chrome lag at all

Screen burn in with AOD.

I hate to say this but AOD might not be a good choice on this watch. I have had AOD on for the past 2 days and right not when i got a text i saw that some on the watch face was still on the screen. It wasnt excessive so im hoping it goes away but just letting you guys know that it can get burned in. And just incase youre wondering. I was using a stock watch face so its not a bad third party watch face. And final thing, on my past 2 smart watches you could tell when the watch face would shift every minute with AOD but with this watch it doesnt seem to shift the watch face at all.
I know Tizen states on their website that AOD does move pixels, but I'm sure it's harder for analog faces over digital and the size of the screen.
https://developer.tizen.org/design/wearable/watch-face
Scroll down to "Screen burn" and you'll see they state it moves.
Now I'm not saying it's not possible, in fact I myself don't trust the size of the screen and disable AOD on my watch.

Did the burn-in go away? Which watch face were you using?
Thankfully it did go away. It was the Urban Classic watch face. Looked so nice with AOD but not going to use it anymore

I just turned my AOD off, just got it today, dont want to take a chance. Until we find out more
Plus with how fast the screen turns on when you raise your arm to look at it, don't really need it much.

I tested the AOD with a third party watchface that i used to use with my gear s2 and i know that for sure it would move around every minute and the movements on the gear s3 were so small that most watchfaces should have an issue with it. Even the stock one. Defenetly dont use it for now. Hopefully they change it so that the watchface shifts as much as it did on the s2
Although AOD consumes battery life and may even result in screen burn, I think that it adds a great deal aesthetically, if not functionally, to the watch. For me, this is very important. Even if I have to charge it nightly or file a warranty claim.

I agree. Are burn ins covered by warranty for sure? If so the ill use it anyways because it looks much better with AOD
After 2 days?
HIGHLY unlikely. Almost impossible on any display.
And I've used AOD since I got the watch on release. No kind of screen issues.
I've had my watch for almost 4 weeks now and have used the AoD since then and I've not noticed any screen burn at all.
Fingers crossed it remains this way.

I agree with you 100%. I usually put my watch on the charger when I get home from work. It's anywhere from about 60 to 75% charged. That's with the brightness up a notch to 8 and AOD. I make no effort to conserve the battery. It charges up in an hour or two and I put it back on.
AOD is a must also. When I'm sitting at my bench I can just glance down and see the time, no wrist flick needed. My guess it will take a very long time for any kind of burn in. By that time the next latest and greatest will be out.
I also work in a heavy industrial area, I have yet to damage this thing but it's going to happen. By the time there is any screen burn it will probably be low on the list of defects.
my wrist flick only works only half the time. I'm not sure what I'm doing wrong. Any suggestions on how I should be flicking my wrist?
You don't have to "flick" your wrist. It's just the rotation of your arm. You can do it slow or fast. Just turn your arm round to show your watchface.
I feel the same way. Had the watch about 3 weeks now and AOD on since. No issues here. I even have a 3rd party face.
I guess ill try it again after a factory reset. Hopefully it was just a glitch for me.
Good morning, I'm noticing an excessive consumption when AOD use, about 1% every 30 minutes, AOD off the battery might not go down every hour or more. I am connected to iPhone 7+ I have everything turned off except Bluetooth, use face Samsung Watch Dashboard Gear. also consumes too much energy in AOD with brightness at minimum.
It completely depends which watch face you are using. They all have different AOD faces, and use different amounts of power.

1%/30min. is normal. That's 2%/hour which means you will have about 50h (two full days). It is the same most of us get out of it with AOD
Code:
If you are worried about burn in use faces that don't have a lot of colors that include blue( purple, white, etc). The lifetime of the blue emitter on OLED is the least by far and is most susceptible to degradation (burn). The lifetimes of red and green emitters are much longer so colors that use those are not likely to burn.
Display orbiting only helps a little, instead of burning a lot in a small spot you will burn a little in a larger spot.
Blue is also the least power efficient, it takes more power to light a blue emitter to the same brightness as red or green. So faces with a lot of blue in them (or colors containing blue) will drain the battery faster.
Since the S3 is new, we're all speculating on the possibility of screen burn. But the S2 has been out for a year. Are there any S2 users who have experienced this problem?
