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.
Greetings,
Just received a used device and noticed my unit won't physically lower in brightness at around 25 percent. What I mean is that at around the 25 percent mark, I am unable to perceive it getting any lower when set at a lower percentage. I've also noticed that when I have the brightness at a high percentage and then quickly lower it to the minimum, that the display will at first be quite dim then will suddenly raise itself to a slightly brighter minimum. I do not have auto brightness on, nor any filter apps active while testing. Just wondering if this issue is isolated to my device. Thank you for reading my concern. If anything is unclear, I could try taking a video of the issues. Anyone else with these issues? I've searched the web to no avail.
i just bought a used device as well and mine has the same issues. the backlight seems to flicker on the second screen at low brightness and below about half the second screen is noticably dimmer. its unfortunate that they didn't put a lot of effort into the screen software or quality considering its the main gimmick of this phone, but it is made by ZTE after all. the price you probably paid for one of these things is a lot more representative of the quality than the original MSRP. But its still a fun gimmick even with all the flaws.

Thanks for your thoughts and input. Yeah this is quite unfortunate on how the phone turned out. I also see the flicker on the second display. But as you mentioned, the device is indeed quite fun. I'm actually thoroughly enjoying the device especially with books and comics reading in the extended mode. I tend to do some late night reading, so that was the reason why I brought up the display issue as I had wanted to get the display as dim as possible before applying a filter. Hopefully one day we'll get root to check out if we can lower the display minimum brightness level along with other lower level system modifications.

apparently a few weeks ago someone released TWRP for this device. its not quite a root but it still gives you root access to change the build.prop and some low level system settings. TWRP is the sign that there is some kind of development happening but i wouldn't hedge your bets on anybody fixing the screen issues even with some kind of kernel modification

That is definitely a most welcome update. I'm curious on what build your device is on since you mentioned having similar issues to mine. I am on b30 myself and will be flashing to b37 when I get a chance to see if there are any differences.
The display on this phone has substantial problems with motion blur, and I'm floored that nobody else seems to be talking about it. I've already replaced the phone once, and both the original and replacement have the same issue. When scrolling text (especially darker or bolder text), there's noticeable smearing of the letters, and 24/30 fps videos look awful. I'm about ready to return the Ultra and find something else, because it's pretty severe and I can't unsee it.
Is anyone else noticing this?

No can you post a video showing what you mean
I’m surprised too that people aren’t commenting on this. I have noticed the motion blur, particularly bold black text on a white background. This is at 120Hz. My Onplus 8t has a 120Hz screen and it has less blur but is not quite so smooth when scrolling. However, the S21 ultra is way better than my iPad Pro which is complete smeary mess.
I noticed it too, especially compared to S20+ which I also have. It almost looks like it's on 60hz instead of 120hz.
But I can live with it.
I also have significant motion smearing with my S21 Ultra. I did a side by side comparison to a OP7tpro to make sure that it was not my eyes playing tricks on me. I also tried with a friend's S21 Ultra and it yielded the same result so I know it's not a random defective unit on my side. I notice the issue prevalent on videos that are rendered with the HEVC codec. I really hope Samsung has an update that fixes the issue. The whole point of getting an Ultra phone was for a no compromises phone and this hasn't been the case

Let's see if the iPhone 13 has this issue.
Can you recommend a YouTube video or a link to video file to see this effect on?
(This answer was made by using past experiences and pointing out some interesting things that have happened so this is not guaranteed to be correct and id recommend for someone to confirm this first)
Id say its just the ghosting (not too sure as ive never owned this device but its most likely to be it)
ghosting is basically a little imperfection on many screens that make the frames ghost out a bit as the next one comes in makimg the effect of the motion blur.
The info after this may be false (recommended to test the info incomming and see for yourself) but can help with finding out what causes ghosting:
Having a look on my laptop screens and looking at how the stuff is it seems to either "paints" (usually happenes when a games in fullscreen. chunks of the screen loading in, it dosent happen instantly with the whole thing), or either suttle ghosting (when you see your cursor and your desk and are at the os itself, im not sure why this happenes though, if the software or drivers were to do this on purpose why they dont choose to or cant when somthings truely fullscreen)
This dosent happen on phones and all i see is suttle ghosting BUT ive seen that in bootloaders and in recovery this does "paint" instead of ghost
ive also seen that without drivers and stuff (like going into win 10 setup) it also paints
So im not sure if the drivers or smt else is doing this on purpose and why or how they have chosen this to happen for quite some time.
Hi. I don't have any way to show this but my unit has what I think is backlight bleed when displaying a fully black (#000000) picture.
This bleeding is somehow especially visible at 35% (don't ask me why) and 100% brightness.
Now, it's only really visible when in the dark and when my eyes are used to it so it's not a big deal for daily use. However, this screen is supposed to be AMOLED which presumably works on the same principle of OLED displays.
My OnePlus 3T, with the same picture of a plain black background and with the brightness turned to the max shows no sign of any light whatsoever, as any true OLED display should.
My Zenfone 8 however has a weird pattern of tiny scattered dots and a few vertical lines you can barely make out all around the display and especially along the left edge of the display.
Can anyone with a Zenfone 8 check if they observe the same effect ? Like I said, it's only visible when your eyes are well accustomed to obscurity. I tried repeating the experiment yesterday when going to sleep and didn't see anything at first but I woke up later that night and sure enough, the same pattern was visible again.
In case you're doubting the file I used to test it out, here it is. A fully black pic. Of course you have to watch it in fullscreen so that no UI element can pollute your vision.
Any insight on what might be happening would be greatly appreciated.
Used your file and checked it in a pitch black place. Can't see nothing on full brightness. I still had the home-recent apps slider on the bottom but covered it with my finger. I couldn't tell where the screen is at all.
Maybe yours has some defect but if you cannot see it without hours of eyes adjustment than I think you are exaggerating quite a bit.
I've been using the LG V30 which also has OLED but it had a grey lighting always. Don't know why. This screen is much much better.

It's not like I was purposely trying to find flaws in the display. I was looking for a wallpaper while in bed and as I was zooming in a picture, I noticed as if what I initially thought were color variations in the image remained static on the screen. It wasn't due to a dirty screen. In doubt, I tested with the black picture and cranked the brightness to emphasize the issue and it was clear something was up.
So even if this issue can't be seen during the day, it's still something that can be seen in normal use when using the phone in the dark.
I just went from the my PC to a dark room and tried to reproduce it with brightness at 35% and I could see it in a matter of seconds.
One of the key factors that made me buy this phone in the first place is the AMOLED display. If it's actually defective, I might as well get it replaced. I would just like to know if it's worth the hassle or if every unit has that defect maybe due to something in the manufacturing process.
Can't see anything like that on mine. Totally black everywhere. Try exchanging the phone. Or just give it back and get another so they will not try to repair it.
Thank you very much for your feedback.
The only way the pixels can light is if they have current. Otherwise they are black as night.
Bad firmware or defective hardware.
Try clearing the system cache.
My display has that too, but only at 60 and 120 hz. At 90 Hz, the Dysplay is without lighting, so black as it should.

I don't have the option in the bootloader to reset the system cache, only "wipe data/factory reset".
I selected it thinking it would let me choose what to wipe but then it warned me about permanently deleting everything so I nope out of there.
Any other way I can do that ?

It's in Settings somewhere under storage or memory.
On Samsung's it's on the boot menu.

That's it! I got the same behavior. Perfect black at 90hz, grey goo at 60 and 120. Since I'm not the only one, I suppose this is "normal". I guess that must be some sort of compromise they had to make for the display and they hoped people wouldn't notice.
It's a shame but at least I'm relieved knowing the screen works well at 90Hz. Since the 120Hz was not one of the key features I was looking for, this doesn't feel too bad a compromise to deal with.
Thank you everyone for your time and replies.
Interesting, I hope this is a software issue that can be fixed with an update...
Same.. When viewing black wallpaper @60/120 hz, it got scattered gray all over the place with a vertical line in the middle. Noticeable if you're in a dark room. Glad i'm not the only one
Alright, so I was able to capture a long exposure photo of the phone on a black screen. The issue appears on 60 and 120Hz like mentionned above. I found that it is more apparent on the 120Hz mode than 60Hz. 90Hz is flawless. The effect is kind of exagerrated, but it was the only way to visibly capture it.

Also during restart, the "Zenfone" loading screen appears like that in dark room.
Same behavior here, 120 and 60Hz are not truly black. 90Hz is.
Quick reply to add here that for those that use the phone at 60Hz, you can enable DC Dimming, that solved the issue for my device. 120Hz still needs to be figured out though...

Interesting.
DC dimming can reportedly have its own drawbacks as well like skewing color rendering.
What is DC Dimming & Why it's Important for AMOLED Smartphones? - Gizmochina
OLED panels have a lot of advantages. They have better color accuracy and contrasts (including better blacks) and are thinner and brighter than traditional LCD panels. So, it’s no surprise that smartphone manufacturers are shifting to OLED panels for their smartphones. Even the mid-range ones...

after further investigation and trying to replicate on several ZF8's, it seems that this is a normal behavior. The questions is: is it hardware or software?
Hello.
After a few months with my Exynos S21 Ultra, totally happy with it, yesterday I went to the beach for the first time to discover a terrible issue: if the phone gets warm, under the sun, the display dims down becoming unreadable.
I immediately thought about a problem in my device, trying to restart it several times, putting it in safe mode, checking every possible menu or submenu.
Nothing.
I moved to a bar, inside, and after a little while, everything went back to normal.
I tried to Google the issue and discover this is something "NORMAL" for Exynos phones (found a thread about the S20 Ultra):
if the phone heats, the screen enters a sort of "safe mode" dimming itself down to an unreadable point.
This means you can barely take pics because you see nothing in sunlight.
This is something new for me because nothing similar ever happened on my previous Note 10.
Anybody?

Not sure what anyone can do about this. This is not exclusive to the Exynos 2100, happens with the SD888 too (probably more often) and not just on the S21U, even the OP9Pro has similar thermal issues.
When overheated (either due to intense processor activity like Camera use, or external factors like ambient heat and sunlight) the phone will throttle down the CPU, close energy intensive processes like camera and dim down the screen among other things to minimize thermal damage.
It's not a pleasant experience, but it is what it is...

I don't know.
iPhone can mean many different models, just like "android phone" can mean many different devices.
Not all Android phones have the above issue. This seems to be an inherent issue with the current architecture of both the E2100 and the SD888. They run hot, especially on the S21U and the OP9Pro. Once in a while we get chips with less than desirable thermal personality, just like the SD810 had in the past. If it's going to overheat, it will sacrifice performance and features to facilitate cooling down.
That's all I was trying to say in my post. I know you're not a new member here, so I'm presuming your question was more rhetorical than literal. If something I said ticked you off, it wasn't intentional - I was just pointing out the way things are with this generation of processors. And I don't think it's user rectifiable without crippling device performance.
If you have a solution to modify the E2100/SD888 thermal behaviour, please let us know, I'm sure a lot of grateful users would like a phone that doesn't heat up under heavy load.
