Brightness - Verizon Samsung Galaxy S 4

Ok, so I have my brightness all the way up, and I am still having trouble seeing my screen, and yes, it's bright out, but I don't have it in the direct sun light. I know that my iPhone had no problem with screen being brighter outside. I have the auto brightness disabled. Now, when I bought the phone they put a glass protector on it which is clear, and I also have it in the Otter Box case as well. Could this reduce the brightness? Lastly, if the phone is what it is, then is there an app that will make the display brighter? Thank you so much.

use brighter backgrounds, they will eat up battery a little bit quicker but the brighter colors will actually make the screen brighter. using a black background will cause the screen to produce less overall brightness.

Wow, never gave that a thought. Thank you so much, I appreciate the information. I am off to find a brighter background.

If I remember correctly, the screen can get brighter with the auto brightness turned on. Can't remember where I read that, but the thinking was that super bright mode may damage the screen if it's on that way all the time.
Don't forget, Iphone has LCD, we have Amoled, which one of the drawbacks is, it sucks in the sun.

I will give Lux a try thanks.

on top of the auto brigntenss through android, i believe that samsung has a lowe level brightness auto adjustment that changes depending on the image on the screen eg darker when the image is bright and vise versa

It is called CABC (Content Adaptive Backlight Control).

I am not sure how Lux behaves with this feature though.

Muddy / dark band(s) on screen when dimmed?

Hi Guys - great phone which I've had a week or so now. Upgraded from the first Galaxy S.
Now I must admit to having very good eyesight (sometimes wish I couldn't see finer details!) and..
On white / grey images (download the various screen test apps to have a look for yourself)
The screen, when on a low brightness, is "muddy" and demonstrates a few vertical darker lines on the screen with mine showing quite a prominent one in the bottom right heading up about half way up the screen.
This is mostly visible when the brightness is at a minimum (regardless of auto or the powersaving options)
When the brightness is turned up it is barely visible, if at all... looks fantastic..
But.. at this point I preferred the screen on the Galaxy S which, when dimmed was more vibrant and didn't have this "problem"
Hands up who can see what I see? Any darker lines visible on your white / grey backgrounds? a side effect of this new subpixel arrangement? totally normal? some pixels not as bright in a row hence darker lines?
What do you guys think?
Cheers, B
W
Could you take a pic or something?
ASAP yes (no camera ironically so will have to ask a colleague!)
hold menu and press power button for screenshot off the device.
Yeah, mine set to minimum brightness and has some line artifacts like when LCD supplied with low voltage. (low brightness setting)
Easily noticeable when displaying grey colors.
I'm also using Screen Filter app, setting brightness even lower, some black points around 0.3cm is exposed at night.
Not sure those points are affected by anti-scratch film though.
Hola
I can confirm that I see the same "line banding" effect when using the device with low brightness. Like others have mentioned I also use the free Screen Filter app to get even lower brightness levels especially when reading stuff in bed in the near dark.
I would think this is a side issue with having the Super AMOLED Plus type screen but I guess only a Samsung tech can confirm.

65" long exposure exposing some black spots.(digitally enhanced)
Lowest brightness + Highest brightness.
Wondering those spots are caused by screen protector or defective screen or limitation of current AMOLED's.
You can see there is some current leak.(It should be bezel-like black if it is ideally off)

Not sure I understand you cpu98!
Is there a consensus we all have this "problem" - i'm on the verge of taking it back for a refund and "monitoring things"
Anyone understand the tech / spoken to Samsung?

Not sure what those black spots are... is your camera messed up? There's spots on the right even off the phone...
Also yes, pure black for SAMOLED still produces SOME light, but it's almost indistinguishable to the human eye.
Take a picture of a dark grey image on low brightness and it should show the bands the best...

That spot off the phone is on the wall not defective cam. As you can see photos are taken at different angle. And it is visible in naked eye.
Yeah I like its screen very much. That black issues are no problem in real use.
I'm very satisfied.

[Q] is low brightness bad for the screen? (maybe burn-in?)

I'm always using the lowest brightness (0% or whatever it is), at stock browser there is an option to change brightness too so you can get even lowest brightness then you got...
While I'm doing that I've notice that there are some pretty invisible lines - about 2 vertical lines on the right side of the screen - while viewing white or gray page.
The more the brightness is lowest you can notice it, and the more the brightness is higher you could not see it.
Its not like the burning screen thing as I never keep the screen on too much time on the same point (and always using Live Wallpaper), I know how its look like because I had it on my Nexues One... its showing only when using lowest brightness and could see it on white or gray wallpaper (I've notice it on google search at browser)
Anyone have any idea why is it happens (again, when you make the screen brighter its gone) and is it safe to use the lowest brightness or should I avoid it and put the brightness to little bit more ?

AFAIK it is not dangerous for the display.
There are many screen filter apps available to lower the brightness even lower, and never heard someone reporting a damaged screen because of this.
Usually, your lower the brightness of the display to reduce the battery consumption for a better battery life.
If that is your aim, then try to use as black background as possible.
With dark/black screen the battery consumption of an OLED (like our AMOLED) display is lower than on light (white) background.
And you won't see the "pretty invisible lines".
maybe a burn in ...

Well, actually when I thought about it I was playing a game "Jetpack Joyride" for almost two hours continuously and played it a lot at the last days, even though the screen at the game is changed every time, the 'roof' has some constant lines, so maybe it cause the 'burn in' vertical line/s that I see.
The weird thing is that burn in looks better and 'tougher' when using higher brithness and not lower as in this case...
When I put high brightness the 'burn in' seems to dissapears.
Is it possible or its something else? [I know AMOLED screens are pretty sucks about that situations of burn in things]

Bland Screen

Check out this picture. My HTC M8 is on the left. New S6 on right. Both turned up to full brightness. My M8 screen looks so much more vivid and colorful. Anybody else seen this issue?
Have you checked your gs6's display settings? I'm curious if this is a hardware issue on your device or if it's just one of the other profiles - make sure it's set to "adaptive".

check to make sure auto brightness did not turn off. For some reason many people, including myself, have seen the auto brightness become automatically unchecked and brightness lowered.
I too came from the M8. I have yet to decide which screen I like more. I love AMOLED blacks and colors, but the screen seems so dim (especially if you've been looking at any other screen) and the whites seem yellow.
Full brightness on recent Samsung flagships is achieved on auto brightness in full sunlight, not in the dark. If you did this outdoors at noon you'd have a different result.
Make sure auto brightness is off and adaptive display is on
I took this picture inside. Auto brightness was off. Adaptive on. No power saving mode on. I can't stand auto brightness on phones. I usually keep my screens around 85-90%. Both S6s are going back and I'm going with the M9 or Nexus 6. Way too many issues with these phones.

You must have a bad unit or power saving mode going crazy or something. I have the M8 and M9 and the edge screen is night and day brighter. Like not even in the same league brighter and more vibrant. It makes the M9 look dull and lifeless.
Yeah mine is a bad unit too. It's going back tomorrow. I've played with the power saving and all display modes. No go.

I have the M9 in my hand right now. Camera is awful and it does have heating issues. Always warm. I do like sense 7 over touchwiz but I can't handle the crappy camera. Look at the photo comparison here http://forum.xda-developers.com/galaxy-s6-edge/general/photos-comparisons-s6-vs-t3076641

Let me know if it's any different with the new unit. If so, I may have to send mine back too.
So I grabbed a flashlight and turned on auto bright. I put the flashlight over the sensor and the screen got extremely bright. Way more than having the manual setting at it's highest level. Maybe they'll update the software so we can turn the screen up to where we want it.

I can't use Samsung's "auto" mode for brightness. Always too dim for me. I have been using Lux Auto Brightness (paid version although there is a free version you can try) for a long time and I find it does a much better job than any "auto" mode from manufacturers. I think they make it as dim as possible to help with battery stats. But it is pointless if my battery lasts twice as long and I can't see the screen LOL
Thanks. I'll try that.

Yep, just look at this image:
I really hope there's a hack that gets max brightness without auto brightness. I stay in a dark environment so it always keeps it on the lowest brightness, waaaaay too low, especially compared to my computer. I want the max brightness (I know, I know, bad for eyes, whatever), I mean, that's what the slider should do...

try lux auto brightness. You can set your values to what you want in each environment and time of day. Love it for fine tuning how my auto brightness works. The only issue with the edge is the screen does not blur when you swipe out your contacts from the edge. Hopefully they will fix that soon.

Second screen brightness

I've noticed today that my second screen seems to get stuck at a brighter setting when the main screen is off. If I wake up the phone and put it back to sleep it will drop to the low brightness and look normal. I am rooted and on the stock debloted rom. Has anyone else experienced this?
Also another slightly related question, but is the second screen an actual hardware second screen or is it software just using part of a large display? I only ask because when in TWRP it shows everything as one image and I cannot see any line differentiating that there are 2 screens.
There brightness is governed by the light sensor. You might have too much light shining onto it so it gets stuck at the higher setting. It's very sensitive so even moving it a few inches away from a nearby lamp might help.
The second screen is just part of a single LCD panel and it's the software that displays different stuff on it. That's why TWRP looks the way it looks on it.
Is there a way to manually adjust the 2nd screen brightness? At work my 2nd screen is so dim that i can barely even see my notifications, which is the point of the 2nd screen lol.

Minimum brightness?

Every post bashes the low brightness outdoor, but what I want to ask the users of this phone is if the minimum brightness is bothersome in dark environments like at night with lights off. Because I plan to do some light reading like that.
The GSMarena review mentions that lowest brightness is blinding 14.9nits. Is it really that bad?
Please let me know, I'm thinking of buying this phone.

By text you mean reading ? This phone display is definitely not suited for reading, the text is blurry/fuzzy.
