Screen Brightness/Color issue?

So I've noticed that when I hold my GS3 next to my sisters hers looks brighter than mine, hers isn't rooted it's running stock TW. I'm not sure if it really is a brightness thing or if her colors are just more vibrant, I can't really tell. Also the bottom of my screen is oddly brighter when viewing blacks than the rest of the screen. Anyone know what this is or if it's fixable? I read somewhere that morfic's kernels make the colors more accurate or something like that but I'm not sure if it's true.
Info:
Rom: Frosty JB v3.0
Kernel: Stock
Modem: LI7

Gotta replace it.... My old one was yellowish. Now my new one makes a popping sound when playing music, you can't win them all.... My first one had a broken power button
Samsung quality control is ****

Are you using automatic or manual brightness when comparing? Auto brightness on a lot of JB roms are somewhat broken.

Manual for both, I flashed higher brightness levels that Wanam made and that sort of fixed the brightness thing. When comparing on lowest brightness hers is still noticeably brighter but on max it's about even. Mine actually looks a little brighter but the whites on her screen are more accurate or "crisp" so it appears that they are about even when mine is most likely brighter. This didn't fix the black screen issue unfortunately, I think it's also important to note that she has a white GS3 and I have a blue one, I looked on the internet and in some comparison videos where they do a side by side of both with a blank white screen the white S3 is noticeably brighter so that may be why.

Not saying that there isn't a problem but it could all be an illusion. With a white phone the color probably makes the screen look whiter or "brighter" as compared to a darker colored border on ur blue phone

That's what I thought at first but I all my friends and others said hers looked brighter as well and it's pretty noticeable with low brightness that hers is brighter.

Are you using any sort of screen protector, could affect screen. Just a thought

Two things to consider.
Toghle the display setting for Auto Adjust Screen Tone.
Also, unless you are both on the same rom you wont be doing apples to apples. DJ' Frosty roms include the Bravia Engine i believe. This alone could cause the differences you are seeing. Odin back to stock, same build as the other phone. Make sure the settings are all identical. (Not just display, but all settings. Dev options, battery saver, etc)
If youre still having different results then you may have hardware issues.
One very Important question to ask yourself....would you even notice that your display might be sub par if you didnt have the side by side comparison?
Consider that before thinking about sending it in. Often you will get a refurb in return which can have much more annoying issues.

Yeah, I didn't really plan on sending it in, it's not that big a problem with higher brightness levels by Wanam so it's not really worth it. I was just wondering if something caused it or if it was a defect but as you said above the bravia engine could cause it so I'm okay with it, I'd rather have my rooted, less bright, boss of a phone running frosty JB v3.0 than stock TW with a slightly brighter screen. :laugh:

I've never really understood why ppl make mods for higher brightness or sound can't that hurt ur hardware I mean isn't there a reason why the max volume or brightness is set at that level

Often the levels are set with battery savings in mind. Also i doubt any manufacturer will set ranges to include true maximum as it could shorten device life and some components may have different tollerances from one batch to the next.
Yes setting levels too high can cause damage if you are not careful. People still make mods for this stuff for the same reason they mod every other part of android, to get more out of their device! Just about everything you see here on xda comes with some level of risk.

I had this problem when I was using the power-saving feature.
Even after disabling powersaving my screen was all dark and messed up just like yours.
To fix it I had to enable powersaving, then go to power saving options and uncheck all four of the powersaving methods, then finally disable powersaving.
Only after that did my auto-brightness start functioning correctly again.

Thanks! I'm not sure why it didn't effect her screen since she also has power saving on but after doing this my screens back to normal now.

Does anyone have the brightness mod? I went to the original link and unable to download it. Thanks in advance.

Possible "auto-brightness" glitch?

When i select auto-brightness it takes my phone to the lowest possible setting regardless of the environment lighting and it stays there
wondering if i should take the phone back if it's just my phone...anyone else experience this?

Hmm mine seems t I slwsys be low by the I like it like thst.. Have not had a chance to take it outside yet due to the hurricane
Sent from my SPH-L900 using xda app-developers app

thanks for the feedback...i compared it side by side to my gs3 and my gs3 works as it should...my Note 2 goes all the way down to the lowest setting..
BTW im in north east MD...the eye past directly over us here ..we are about 1 hour and 20 minutes from AC new Jersey...

Mine also appears to be a bit on the low side. It is not at the lowest, but auto never appears to hit the highest brightness. When i am in sunlight, i have to untick auto and move the slider to max in order to comfortably read the screen. Hopefully it will get fixed.

I've always thought Samsung's auto brightness sucked regardless of phone. The note 2 is no exception.
Try some apps in the play store, they work better.

SGIII didn't have any issue with brightness at all. At least for me.
Galaxy Nexus is absolutely horrible on the other hand. And I'm too lazy to play with AOKP adjustments so I have to do it manually everytime.
My Note II does appear a little darker than it should but I thought it might be only my perception. I'll take closer look at it.

I thought I had the same thing. My phones brightness is all the way down with the auto box checked. I did however uncheck it and then the brightness dropped way down. I chalked it up to auto taking over and misrepresenting what the level of the brightness was on the screen. Dont know if you are seeing that or if you are seeing a true glitch.

i thanked all for your feed back...its obviously not just my phone...again my GS3 works very well...my note 2 not at all...I wonder if samsung set this up like this on purpose to save battery..either way auto-brightness is unusable for me...

Let's give it up for Intellicover!

This app is MY FAVORITE ANDROID APP EVER.
- Virtually zero battery drain
- I never ever EVER have to touch on/off button now
- Tons of customization settings
- FREE FREE FREE
- Works awesome whether i'm using my poetic cover, just putting the phone loose in my pocket..or even if its just sitting out on the desk and goes to sleep (just put your finger over the sensor briefly to 'wake' it)
- You can turn off the 'auto on/off' when in landscape mode which is great..i never accidently put the phone to sleep while showing someone a video
- Set it to work automatically after rebooting phone
- Set it to automatically release the lockscreen (if you dont have a passcode)
in short..this simple app has quickly surpassed everything else i installed because it so simple and elegant!
2 thumbs up! i'm planning to buy this guy a beer or whatever his little thing says.

Interesting idea for an app, but not for me. I like to keep my phone out on my desk during most of the day and I'm not a fan of having it face down especially since I don't use a case/bumper/screen protector.

you dont need to.
it will go to sleep like it normally does. it would only turn on if you put your finger over the sensor for a second.
give it a try..you'll fall in love w/ this app!

Yes!!
I just replaced the LG bumper case with a Nillkin flip cover last night and immediately started to hate having to press the power button to unlock it. Now I just have to open the flip cover for the screen to turn on. I've only been testing it for a few minutes but so far it's been perfect.
garenzy - I leave my phone on my desk with the flip cover open as well. As nyvram1 mentioned, you just need to wave your hand over the proximity sensor and the screen turns on. It's been flawless for me so far.
Loving this app! The verdict is still out on the battery drain but I'd be willing to take a small hit on that for this new feature.

i've had this installed for over a week and haven't noticed any additional battery drain.
read the developer's notes. he explains why the battery draw from using this is negligible at best.
i LOVE this app! seriously, after using my phone for a month without it, then installing it a week ago its like i have a new phone!

I dig it, I have my bumper so putting it face down at my desk isn't an issue and it's nice not having to feel for the power button.

doesnt matter if you put it face down or face up on the desk. it will obey the normal timeout sleep if face up and you just move your finger over the sensor to 'wake it' if you need to use it.
no downsides to this app yet.

I haven`t installed it yet but how does this affect the lock/unlocking of screen when you put it in pockets or put it in your bag?

Installed, can't decide if I actually like it or not. Seems to flick on and off all the time despite messing with the settings. Works well when I put it in my pocket.

Tried it, it killed about 14% battery overnight while I slept :/ not good so uninstalled.

Fun gimmick app, I can see the usefullness when you're using a flip cover, however I don't so it's just a cool gimmick till sleep2wake becomes available for other kernels. That how i want to turn on my device

So 24hrs later it's getting uninstalled, everything seemed to be working fine but on calls/alarms/etc. it doesn't show the appropriate screen it instead shows the home screen (I did set it to go to the home screen but that was so it didn't stay stuck on the intellicover screen) so for now I'll just go back to tapping the power button

[Q] Smart stay - yay or nay

so I have just recently purchased my note8 and Im still trying to get the hang of it. I notice that I frequently qet message saying that the smart stay can't detect my eyes.
I also notice that I rarely see the eye icon lights up (I assume its there to indicate that the feature is active).and one time, the screen went blank just right after the eye lit up.
maybe, speaking from my limited exp, just maybe, the smart stay works better on devices with smaller display as the variance of the eyes/ face orientation will be much smaller compared to on an 8"device.
While I understand the benefits, the question is how many of you find this feature reliable on this tablet? pls feel free to share your experience on how it performs on smaller devices.
Im thinking I might as well turn it off in exchange for some extra battery life.
thanks / Luke

Can't share any experience using this feature as turning it off was the very first thing I did after purchasing my device
I think the drain should be way too high since it uses the front camera all the time, doesn't it? Anyway, it happens maybe once a week that the display turns off when I'm actually looking at it - at most. And just before the display turning off it dims the screen, so there is still some time to react..

I find it doesn't work as well in the dark as my GS3 did under earlier firmware and I do often get the icon. But smart stay does work well for me. Unless I'm laying down on my side.

It checks every 15 seconds of inactivity to see if you're still looking at the screen. If you're not according to your front camera, it'll dim/shut the screen.

Mine only checks a few seconds before the screen is set to time out. Ie. If the screen is set to stay on for 2 minutes, it will check at about 1:50 of inactivity.
I kind of like it except, as posted above, it can be a little iffy in low light.

I really think it is almost completely useless and simply a waste of battery. I've also disabled lock screen. Nobody touches this tablet but me. When I use it I want it instant on, and when I'm done I turn the screen off myself. I hate my devices trying to decide for themselves when to switch off, and first thing I always TAKE THE POWER BACK!

Thanks for the feedback everyone. l have been trying it off and on but at the end I would have to agree that it doesn't work for me. I cant say how much power saving I get by turning it off but it feels good to know that some resources are relieved for something else.

I use it on my note 2 (8 months now) and note 8.... it doesn't burn much battery.... it works better on the note 2 because your face is exactly straight on the camera... On the tablet.. Usually we hold it slightly at an angle.. So the camera sometimes misses off

After reading this topic, I charged my Note 2 and disabled this feature to try to get more bvattery life.
The difference is like night and day. The screen consumes a lot less power (according to the JB's Battery widget) and the battery lasts much longer.

i've never used this on any of my devices. i always seem to have this odd habit of turning off electronics when i'm not using them

A big NAY for me, I just haven't been able to get it to work even a single time, keep getting the "Smart stay cannot detect your Eyes" message again.
Is it that bad, even in other device like the S3 or S4? S4 has so many features(like the smart pause based on it, makes me think I can't use it properly), any tips how to better the usability(other than the usual ones given by Samsung)?

Just bought a V500 in the UK. AMA

It arrived today. Had a play and set it up as I wanted. Following the guides here, rooting took about 30 seconds (had to do it twice though) and I used flashify to flash the twrp zip. All super noob simple. No driver needed for me but I've had both LG P920 and Nexus 7 drivers installed already.
Issues so far:
Bleed - none.
Blue line - none.
Yellow hue - none.
SD card with TiBU etc - works perfectly.
Dim screen - no and in fact I set it to 60%. Full brightness is too bright.
Thin black border around screen - yes but how could it bother you?
Poor speakers - yes, they sound tinny/echoey below half volume. Fine above that. Think it's the aluminium back.
Battery drain - yes its quite fast. Set CPU to 1.1ghz and removed some bloatware its much better.
I'm sticking with the stock ROM for now. I'm familiar with the LG system and the apps are quite cool. TV remote works far better than those crappy 3-in-1 remotes from poundland.
Anyway, it seems to me that the screen issues have been resolved, at least with mine. I'm very happy with it. Any questions, fire away. Injustice is much nicer than on my phone.

What did app/software did you use to limit the cpu and cleanse bloatware?

I used ROM toolbox and titanium backup. I like SetCPU cos you can set voltage levels with a custom kernel but I don't think one has been made for this device yet.

As I mentioned in another thread for bleed there are 2 issues with this tablet. Traditional bleed which my latest tablet does not really exhibit, and edge light brightness. This is something only noticeable when brightness is at 20 and below. It is always on the bottom screen area in portrait mode and seems most visible on white background (i.e. white picture or browser page when turned into landscape to the button bar(when set to black theme) is not obscuring it. You will see about 7 bright white spots at the very bottom tablet in a row. I suspect this is a limitation of the used display technology. If you look at this video by another owner on youtube you will see what I am describing under the above conditions:

Hmmm now I am not sure what to do.
First one I bought was a white one. It had traditional light bleed in 2 corners and had this bottom edgelight issue at low brightness.
Returned it for a black one. This one is better in that it has no light bleed except the bottom edgelight issue. This occurs at brightness below 20-25. IT is not an issue during day time as I am needing brightness above 40 to comfortably enjoy the screen.
But for night time use I have to kepe the tablet a bit brighter than I prefer so as not to see it under some circumstances, I.e. landscape viewing.
I am trying to decide if it is worth returning as I love everything else about it. I am on vacation in the US and do not have the time to keep going back and forth to various best buy locations hoping for a better unit. Especially since seems the black model is in limited supply with nearest store 30 minutes away. However also given the exchange rate on my credit card, Returning it will likely cost me 20$ based on how the Credit card companies charge....

Where did you buy it from? And for how much?

eBay, around £220-£225. Can post link if you want.

what bloatware is installed on the tablet just curious ?
about to buy the tablet real soon, in regards to what you have said about battery can it last a day o more at least ?
does setting the cpu require root on this device ?

Bloatware: Well I guess that's personal preference. Stuff I won't use is some LG stuff (home launcher, LG back up etc), live wallpapers, stock browser and video player, Google books, music, movies etc.
Tablet has no chance of 1 day battery life unless you aren't using it very much. It's not horrible though, I've had 3 hours constant use this morning and I'm at 50%. Screen is under 40% for night time use though.
Not sure if you need root to underclock. I always root every device so I've never checked. I guess theoretically you do not.
