I got my S4 last week and it's great. This one doesn't have any lag, or at least not anything that concerns me. However, it does have screen issues, especially with the light adjustment. Sometimes the screen will randomly go full brightness for a second and then go back to normal, I notice this when accessing messaging sometimes. I know it also does this for Instagram, but it is suppose to do that.
Now, sometimes it seems like it does a colorshift. the screen will appear less blue and more yellow. It did this when I was accessing the facebook messenger app once and maybe another one. I might be making this up, but it just seems like the color changes ever so slightly. Also, once in a blue moon when it is adjusting screen brightness, all these vertical black lines appear for a microsecond on certain parts of the screen, it seems like an even distribution of lines. Reminds me of something old game boys might do.
I am very happy with the phone though, and I don't want to switch it if I don't have too. However, if another version might not have these issues, I want to switch ASAP, I only have a week left to swap for a new one. After that, my 14 days are up and they said they would only give me refurbs. :[
Do it.
I'm stuck with a defective screen 16GB because the 32GB did not come in on launch day which was my last day to return.
My only option at this point is to get another 16GB that's refurbished from warranty.
The irony in all this is that I manage the kiosk where I purchased the phone on my personal account.
My employees' phones and demo don't have the same screen issues I have.

I will check out the settings. The events that this glitches happen are rare, but it has only been a week and they have happened numerous times. The auto lighting adjustment sucks, times when it should be bright it's not. Plus the black line stuff that happens sometimes. If all of them experience this I dont want to trade in for another one. I don't want to risk trading my working phone for one that won't work so well.

I would swap it if I were you.. I came from the HTC one because of repeated problems and switched to the s4... I've only had it a few days now but have only experienced some lag (fixed by tweaking settings) and the auto brightness is a little slow to adjust sometimes (I've always though this about all my Samsung devices).. But no color changing or bars appearing.. Just my 2 cents..

that is partially due to the type of color meter and ambient light sensor type (should be a 40-something segment black and white unless my info on the sensor specs are off. i believe apple has designed a proprietary multisegment rgb meter for theirs). b/w meters get lumens correct, but not perceived brightness (human eye is not the same as a sensor).
the color changing issue you are having may be due to the display mode being set on auto (start, settings, display mode) and under lighting that the sensor cannot correctly meter for (fluorescent lights flicker at the same hertz as your AC current, and are actually pretty dim and WAY off for color balance, so that SHOULD throw the sensors off continuously, which would lead to auto brightness hunting and inaccurate selection of the 'correct' color mode).
try turning auto brightness off and color mode to professional photo or movie (i use move as its very flat and closer to real colors). there ought to be a way to trick the ambient brightness sensor to sample and average at a faster rate, and ramp up/down more smoothly, but i cant code for android otherwise i would have been working on one.
i work in tv/film industry on the sensor/lighting side btw. if the issue goes away, turn on auto brightness and check it out under NON FLUORESCENT lighting. if its gone, it was probably the display mode changing along with auto brightness.

I had no idea the S4 had these options. I guess I am used to my Atrix which didnt do much. I went in and adjusted the settings. The auto screen brightness never really did a good job, I feel that it is way too dim in situations where it should be brighter. I will text your advice the next week and see what happens. If I still get issues, I will return it as I have one week left of my 14 days. Thank you very much for the excellent advice!

no problem; the auto brightness on the GS4 is only slightly better than the Atrix 4G (had one too), and same as the GS3. The color mode thing (which is awesome; closer to real life colors versus waaaay oversaturated screens on most phones. also check power saving settings.

Well, I have not seen those black lines since I turned off auto brightness and turned off the screen automatically doing it's own color adjustments. I will turn these back on to see if I can duplicate the issue. I do feel that I have more lag now, but I could just be paranoid.
OK, when I am using my Facebook Messenger App, sometimes these black lines appear horizontally across the screen on low brightness. However, sometimes they dont. I dont want to call them black lines, but maybe I should say they are ghostly tv lines that are barely noticeable. Ideas?
Could someone explain the defective screen issue?, mine looks great...
The phone works great most of the time and is totally useable, the only issue is that sometimes it does these weird things as I have explained. Tomorrow is the 14 day mark, so I am having a hard time deciding if I should switch for another one just in case, or assume all of this is normal and hope the phone lasts me 2 years.

Could possibly be a GPU issue. Have you had any problems playing heavy duty 3d games?
Sent from my GT-N7100
No problems playing the Iron Man 3 game, everything seems fine.
It seems like any time the keyboard is pulled up, the screen shifts color to something more yellow. all of the keys go from a nice grey to a off grey yellow tint color. During this transition, I can literally see the screen transition as weird lines appear for a fraction of a second, like switching channels on an old TV. I tried recording this on my DSLR 1080P camera but it could not pick up the color change visibly. I might try again. It does this on Google Chrome, Facebook Messenger, Snap Chat even. sometimes it color shifts even when the keyboard is not involved. I have the auto adjustments on the screen off and the color set to Standard Mode.
The ATT store said I am a day out of my 14 day limit and there is nothing they can do. They said I have to talk to warranty and see if they will be nice enough to send me a new one. I dont want a refurb, last time that happened, I went through 4 of them. I talked to ATT support and they said they would extend my 14 days another 3 days but the ATT store said I was out of luck for an exchange for a new phone.
So no one elses screen color shifts to yellow when the keyboard pops up? Mine does this now all the time, mainly in low light. It might do it in all light situations but in sunlight I prolly just can't see it. It's incredibly annoying because the screen itself wacks out every time it does it.

When I have my nexus one set to automatically adjust brightness, it doesn't seem to do anything.
I can move it between dark and bright environments and the screen brightness doesn't seem to change at all. Am I missing something or is this feature not working on my phone?
It works fine with mine. I just clicked auto in the brightness setting. Make sure you didn't accidentally change it to a different setting with the settings widget that is by default on the first home page to the right.
works fine on mine yet not a feature i use....i just set it statically.
I find the auto-brightness to be too dim for my liking. It would be great if you could adjust the overall brightness while still maintaining the automatic scaling.
Turns out it does work, it just need to be *really* bright to make it change.
It doesn't change really at all in my office between switching the lights on and off (even though that's a really big change in light levels to me). However, if i go outside, it does get brighter.
As you say though, it does seem to be set a bit low (hence it not brightening up when my office lights are turned on I guess).
If I enable auto-brightness on mine, it seems to constantly vary the brightness in my office. It's annoying as crap and I turned it off. Am I the only one?
It's probably taking a look at the available APIs to see if it's easy to write a quick app to do auto brightness with settings to be able to tweak it.
The auto-brightness feature changes constantly for me as well.
I 'm also having issues of the varying brightness when using auto-brightness -- even though the lighting in my environment has not changed and I avoid contact with the light sensor. It's VERY annoying.
I've since switched to using a static setting for the brightness.
auto brightness was one of the first things i turned off. it was way too dim for me
Not bright enough for me. Doesnt seem to change much.
I do see the variability occasionally. Most of the time it's stable, but it will take spells of shifting up and down repeatedly. Glad to know I'm not alone.
Auto bright annoyed me as well when I first got the phone. Then I realized where the sensor is (top left) and what it was responding to. Depending on where I'm sitting, what light sources are behind me, in front of me but reflecting off of me. It's usually just responding to a light source that's just withing view of its sensor. Also, my hand has shielded the sensor more than just a few times, confusing the sensor.
Now I leave auto bright on all the time, and it more often than not does a good job.
IMHO this is one of the few broken features on the phone. In continuous lighting it jumps from bright to dim to everything in between like a jack rabbit on speed. I still use it to save battery life but it pisses me off regularly.
am also having this problem. it constantly goes much brighter, and then, suddenly goes back to dim.. very annoying... however, the light sensor for calling works well... so, is it a software issue.. hope it gets google's attention and gets fixed in next update...

+1 so I also manually go between three on the widget
Note that the light sensor is under the glass on the front of the phone. Some cover-all cases cover this, and if you use one of these I assume your phone will remain on the dimmest setting.
In general, while indoors it will remain on the dimmest setting (for me anyway), but rise to the necessary full brightness when in sunlight.

There are two sensors, one is a light sensor and the other is a proximity sensor to detect when you've taken the phone from your ear. I think you're referring to the second.

+1 constant occiliation on dimmness levles under consistant light. It goes from way too dim, to just right then back dark again. I too hope that google will correct this with the next update. Hopefully the patch gets pushed soon, i'd like that extra memory
My screen dims in programs like mail and explorer when i open them. I have it on high and auto off but it dims whenever i go into these programs. The home screen and everything else stays bright. Is there something i am missing.
I'm talking out my ass, but the only thing that would make sense is that it's a "safety measure" because all white screens kill OLED screens, like what the Focus has.
I called Samsung about this issue the other day and was transfered to level 3 tech support.
I have my settings like you where automatic brightness is turned off and is set to High..
He had a Focus with him and I showed him that when you set the theme to light instead of dark (to see the transition).. The home screen is set to bright white but anywhere that you navigate from there (i.e. the application list).. the screen dims.. making it harder to read text.. He saw what i was referring to and agreed with me on the problem. He thought it was something to do with WP7 but i told him I tested the HTC Surround and it remained bright white on any page (I know its a different kind of screen)
He put me on hold and spoke to a product specialist assigned to the Focus and said that was how the phone was designed.. He passed my concern along with hope that we may see a patch that fixes this.
On a positive note, I asked about the amount of RAM in the phone and the specialist confirmed 512MB.
I hope this answers your question.
Thanks. I hope they fix this. It is hard to read e-mail in any kind of light.
I'm glad for the dimming, personally.. the all white screen would be uncomfortable to look at on the super amoled, imho.

Thanks, I was trying find that one out.
Noticed the dimming right away as well. I read this on Anandtech's WP7 review:
Microsoft mandates three discrete display brightness settings on all phones: low, medium and high, coupled with an automatic brightness mode.
Click to expand...
Click to collapse
To me, it seems like Samsung tried to artificially inflate battery life by programming dimming conditions into the firmware, while still adhering to Microsoft's front-end mandate.
Tried the other two at&t WP7 phones today and they were much much brighter in email/internet explorer. Would a vanilla copy of WP7 theoretically remove this? Since the home screen doesn't dim, it leads me to believe that it's OS level.
is this only when the white theme is active? or is it when dark is applied as well?
this is pretty lame

It does it on both.
Just a heads up if you're planning on buying a Focus S (or Focus Flash), they do white-screen dimming as well.
Hi
not sure if anyone else has noticed this but it seems that the call end button, the button to view the dial pad and the button to view speaker options are burned into my screen!!! viewing in most apps it is not noticable but if you open internet explorer and go to a new page without loading a website the images of the buttons and very visiable in a brownish color I have had my focus since it was released in the US, I have also checked my wifes focus and it also has this burned into her screen.. Has anyone else noticed this?
Yes, I have the call tile, message tile, and the little circle/arrow burned into my screen. As you said, it's only visible on light colored screens, but it is visible. Unfortunately, unlike the temporary burn-in on new plasma tvs, this burn-in will not go away.
If you want to see something really bad, go up to the at&t store and check out the Focus that's on display. The Focus at my local at&t store looks horrible. I can't imagine anyone wanting to buy that phone if they saw that display model...
edit: by the way I love your weather app, I have had a few problems with it over the time i've used it, and you have always been fantastic with your support. Thanks!
Are you using blue tiles? I heard Blue OLEDs burn out faster than other colors and changed my tiles to green.
I have been using the brown almost exclusively; occasionally I'll go with blue, green, or lime, but the brown just looks the best to me.

thanks for the comment. on to your screen you have the actuall tiles burned into your screen? wow i only have the call end and function buttons burned i think its related to having my display on bright i took it off the automatic.
It's actually not the tile, it's the icon inside the tile that is burned in, but it's only visible on white screens. It's still quite annoying. As soon as the hd7s is out I'm going to compare screens, if the slcd is close to the samoled then i'm jumping ship I think...
and yeah my screen is on bright (not automatic) also. I think my problem is that I have the time out set to 5 minutes, and I never locked it myself

Based on HTC's latest track record with the Desire HD and Inspire 4G, make sure you analyze the viewing angle of the HD7-S. HTC has said it will have a Super LCD but, according to an answer they gave to a customer complaining it wasn't true S-LCD tech, the display will likely be what HTC is calling "Super" LCD...meaning it is their name for the super-sized display...and having nothing to do with true S-LCD tech.
If the viewing angle isn't as good as the iPhone 4 or Focus...or other SAMOLED/AMOLED equipped devices...then it isn't the higher-tech display but just an ordinary non-TFT LCD.
Super AMOLED is a great screen. But the pixel life span is still way short. The Blue pixels are the shortest. The old stats are 2000 to 4000 hours. New information point it around 10000 to 14000 hours. But Samsung didn't release any spec on this.
You should always keep the screen dim and keep it on as short as possible. Reportedly use a red theme will not only preserve blue pixels but also prolong battery life.
No burn in here. I have the phone set to turn off screen within 30 seconds, and have always used Lime colour tiles since it matches the Xbox Live tile.
Just a follow up on this issue, and possible a "what not to do" post. The burn in on my screen is getting worse. On a white screen, I can now see the phone icon, message icon, small circle/arrow, the word calender, and my google mail icon. I have the screen set to time out after 30 seconds, and I have the brightness set to high (not auto).
I really love this new Always On Display (AOD) feature, it's really classy and elegant.
But, one thing I noticed is that the brightness level seems to be automatically adjusted, and when its bright it surely drains the battery.
Is there anyway to set this brightness manually? I tried changing the display brightness in manual mode, but it does not seem to use that settings.
Any suggestions would be much appreciated.
I dont think there is an option, if there is i am also interested.
I personally thought the Display sometimes was too bright.
i..e In a Dark Room and the Light was more ambient than it really needed to be.
Then the misses would ask me to turn off the night light lol!
Always On
Dear All, I just bought my S7 Edge and picked it up yesterday. I'm quite impressed with this display!
I thought the same thing you guys tought... The Always On Display is very bright!
But here is some info that I searched over the internet. Don't know about it's reliability, but seems legit.
New Always On Display
An interesting function that first appeared on the Galaxy Note 4 Edge in 2014 was always keeping a portion of the OLED screen on when the phone is off (in standby), so certain content can be displayed all day and all night long, but with a very small power drain that has very little effect on the battery running time. This is possible on an OLED display with a mostly black background because every sub-pixel is independently powered, so black pixels and sub-pixels don’t use any power.
The new Always On Display mode shows various personalized clock, calendar, status messages, notifications, and images on the main screen when the phone is on standby. It measures the ambient light level and has both day and night modes, plus it’s smart enough to stay off when the phone display is face down, or it senses a dark confined space such as a pocket or handbag. The OLED display produces an illuminated main screen image 24 hours a day so you can always discreetly check it with just a glance. As a result, the OLED Always On Display will reduce the need for a smartwatch, which seems likely to become an endangered species. We’ll cover this in more detail below.
Here is where I picked it up. Cheers Guys!
(Received a message with the information that I can't post url's.. ) sorry...
Type this in google, "always on display s7 edge brightnes" then it is the 3rd link in the url contains displaymate
same, it quite bright, and with my testing if you can keep ut at its lowest brightness, it consumes 0.3%/hr. that would be absolutely great.
there is an app always on display plus which helps in that
if you mark on auto brightness , it will be done
I unmarked Auto Brightness and seems not brights

I've noticed that it is automatically adjusting by the amount of light in the room (and it's quite sensitive, always brighter than needed). It would be great if there was an option to manually set the brightness, but only small bunch of people are actually interested in this.

This app does not changing the actual brightens, seams to be there is no solution yet.
I tried changing the screen brightness to minimum and disabling auto brightness, but the AoD brightness seems to be controlled independently.
Trying out an app called Always On AMOLED - it has a night mode. Gonna test power consumption of both
Mine used to auto adjust but not anymore. I think the last software update changed this.
GS7
I'd love to have an adjustment setting. I'm having the opposite problem as most. Mine isn't bright enough! Oh well. Hope they change that!
AOD brightness fix for Galaxy S9 and S9 Plus. May fix others
This may not help everyone as I am giving you the solution for the S9 and S9 Plus, but look in your settings to see if you have the same thing.
Under 'Lock Screen and Security' select AOD and select 'Show Always'. Once you've selected the Content to Show, disable Auto Brightness then move the slider as far right as possible and underneath that select Show Always.
Job done. Next time you see your AOD it'll be full brightness. It is still not bright enough but better than before. If you then go into 'Clock Style' and change the colour after type and choose a fairly stand out colour, this will make your clock stand out even more.
I hope I've helped at least a few people.

i feel like its to bright... i want to dim it. dont need it to be that clear.... i wil continue my search....
Threw search and having both s7 and s9+ I noticed the 9+ has the ability to adjust the brightness of the AOD very easily in settings or double tap the screen and u see the settings. Works perfect on the 9+ as for the s7 doesnt have the same settings they both say the latest version available is downloaded but it's an s7.. so I just think that setting dont exist on the s7. The brightness is controlled on it's own and u really have no control manually on the brightness.. I think it's a new thing for new galaxies but the 7 isnt gonna do it.. eh.. so I suggest a contrast color which makes it "brighter" to the eye. And basic and big.. it's for quick glances anyways... sucks tho..
Last night, I went to use my night clock app with my new LG v20. On my Note 7, the screen was totally 100% black except for the numbers.
On the v20, the entire screen was stil lit - faint, but clearly still lit up in a light light grey.
Is this just how an LCD screen works, or is there something I have to do in order to get the rest of the screen to go off.
(Note, this includes the 2nd screen which was also lit - and I had the brightness at 0%).

BTW, this may need to be a separate thread - on my phone I notice that the auto-brightness tends to be too dark. Any way I can adjust it to be brighter when in auto mode, or should I just go to manual ?

Try turning off second screen and see what your results are.. Second screen has a seperate black light that slightly bleeds out to the rest of the screen. It was horrible on the V10 but much improved on the 20..

The night clock app has the option to turn off the notification, which also turns off the 2nd screen.
...oops. It did, until I followed your suggestion in the other thread about the more setting to enable time/date when in full screen or notification bar hidden. I'll have to get into the habit of turning *off* the more setting at night.
(Either way, doesn't help with the slight gray background color. I can probably just get used to it as long as I'm not damaging the screen by having it slightly on all night. I need to google if LCD screens have burn in problems I guess.)

Use comfort view on low or medium. Will help lower the ~9000K color temp some and help blacks a hair. Faint glow is typical on LCDs. Higher quality LCDs and higher quality led's can help. Lg skimped here. Sucks they didn't even give us color modes to pick from. The colors are waaay off. But using comfort view dims the blue pixels and helps considerably.

On the v20, the entire screen was stil lit - faint, but clearly still lit up in a light light grey.
Is this just how an LCD screen works, or is there something I have to do in order to get the rest of the screen to go off.

That's just how LCD works, they need CCFL or LED back light to lit up the screen, it's not possible for it to be completely black while turned on. With AMOLED the individual pixels can turn off itself which is why the black are blacker on them. OLED screens also have very high refresh rates which eliminates flickering, this is good for people who are concerned with eyes health.
Lcd doesn't get burn in, but it can get ghost image retention. It was f***ing horrible by the end of my V10 usage.. Never had the problem on the G2 3 or 4. Just the V10, even after factory resetting.

Had the same issue my V10, that is my biggest V20 concern. . My v10 was not even a year old.
I get the engineering and cost reasoning, but not sure I like the lcd screens.
