[Q] Galaxy R (i9103) - your brightness uniformity? - Android Q&A, Help & Troubleshooting

Hello, I bought my Galaxy R and I can see that especially upper left corner and whole upper side of display is slightly darker (maybe 15-20%) than lower right corner and whole bottom side of display.
It is noticeable especially on all white background with minimum brightness.
And when Im writing on keypad the letters on left are like slightly darker than on the right side.
Please, could you write how is it on your Galaxy R (i9103)?
I will be very grateful

Anyone with Galaxy R here?
Please, post your experience

Please the owners of Galaxy R, I need answer quickly!
Does your Galaxy R have little less (maybe around 10 -15%) brightness on top of the display than on bottom?
I noticed it on all white background with minimum or low brightness.
Thank you so much.

That sounds bad.
On my Galaxy R, on a white screen and minimum brightness its even all around, except maybe for a thin white line top right, but its less that 1/10 mm thick and not noticeable in regular use.

nedy2k11, thank you for your reply.
Here I posted three photos of my display.
The first two are with minimum brightnes and the third (the last one) is with brightness set around 20%
People, do you think it is normal and acceptable or can I return my Galaxy R back to shop?

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

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] Heavy banding appears and Disappears when rotating screen

anytime I rotate my s2 in the notifications area I see a faint line that appears on the sides of the screen (usually 2 lines, one on each end, running parallel in respect to the orientation of the screen), which disappears slowly after a couple of seconds. is this a fault? or normal with these AMOLED displays?
mine does this too, as well as many other sgs2's. It's more of a ghosting effect rather than banding. I say it's normal and just a drawback of the super amoled displays.
Please use the Q&A Forum for questions Thanks
Moving to Q&A
so, pretty much all s2s are affected because of the super amoled plus displays right?

I'm not an expert but going by personal experience I would say yes. Although I have only noticed it happen when the brightness is low. Personally it doesn't bother me much.
i agree, it only at low brightness you see it along with yellow tint on left, predominantly on lower left (right-triangle shape)
this has to be software related
does anyone else have an explanation for the banding that appears and disappears?

Screen defect

Hello to all
As the title says it's another screen defect that this phone have
I have noticed a darker area, which make almost a perfect rectangular shape upper to left of the screen and it is visible only in some circumstances
- screen brightness need to be lower that maximum (the lower it is the higher this defect is visible)
- mostly visible on grey image (for example the market startup) see other images in the links

http://imageshack.us/photo/my-images/851/img0635ul.jpg/
http://imageshack.us/photo/my-images/864/img0633u.jpg/
not visible at all on black screen of course but when the screen is off and with a bright light (sunlight of a power lamp) in some right angles I can see some darker dots (looks to be some kind of liquid inside the screen) at the size of 5mm and also this rectangular shape (good eyes need here ) no picture for this because it is not visible with any camera
I wonder how came to this and is any possibilities to fix this such as those screen burners, could these help? or only a screen replacement?
PS: phone have no waranty
Thanks
Screen burns are permanent on AMOLED as far as I know. You'll either have to live with that or do a costly screen replacement.
Ah well, guess I have to live with it, not a major problem but it's looks a bit ugly sometimes.
Just read a bit more about amoled screen burn and it seems that the blue leds are the most that probably get weaker in time and causing this screen burn, and yes this is an explanation why on a blue screen this is almost not visible no mather of the screen brightness
Maybe burn all the screen with a white image, but I believe the result can be worst that this
Thanks

[Q] screen is borders are too bright

Last week I bought my galaxy note 8.0 and later that same night viewing a movie, I notice that, on the lower left corner, there was like brightness coming out from the corner, it was only visible on a dark image and high brightness, but it bothered me, so I went to the store and change it for a new one, but that night I realise that this one had the same issue, not only on one corner, but on almost all borders. It's only noticeable in a dark room and high brightness, but it's there, am I being too fussy? It's This something normal on screens? Or should I go and change it again?

Any way for RGB calibration ?

Hello, I currently own a Galaxy S6 Edge, the black Sapphire one. The problem is that the screen is way too yellowish for me on white backgrounds, I did a comparison with my fiancee's HTC M8 and the difference is terrible.
I used to have some RGB sliders to caliber the screen the way I like on my previous phones. Isn't there any way to do the same on the S6 Edge to fix this ? (I'm rooted).
And BTW I don't want to use any screen filters as it decreases performance, i want real settings.
Thanks in advance
Have you set the screen to AMOLED photo? That should calibrate it to the right settings.
It's even more yellow with the photo mode :/
Bump, no ideas ?

The screen on the S6(E) is pretty darn accurate. Odds are the M8 is likely the inaccurate display and giving a bluish hue to the white instead of how white actually should appear. If you compare your phone and your fiancee's phone to a display that's accurately calibrated, you'll see how close to being accurate the display on your phone is. Also here is the review from Anandtech showing similar results in their display test.
Link: http://www.anandtech.com/show/7893/the-htc-one-m8-review/9
Most people are not used to having calibrated screens and therefore, view the bluish white as the correct white when the correct color temperature of white is more on the warmer side. Also screen filters such as Chainfire's CF.Lumen have very little if not zero performance reduction when running in root mode and they allow you to customize the temperatures for day/night/sleep mode with many options.
Edit*
Here is Anandtech's review of the display on the Galaxy S6(E). While there are small variances from display to display, unless you have a defective unit, I highly doubt there's more than a 5% difference between what you have and the review unit.
