Hi, I just bought this smartphone and I saw that in the minimum brightness with dark theme, both displays have bad uniformity.
This also happens to you?

I just bought a white SGS2 today for my wife. When I placed her SGS2 side by side with mine, I noticed that the brightness level is at least 2 step below mine. Eg, at the lowest level, hers is very much darker than my SGS2 set to the lowest level.
As a result, I cannot set the brightness to auto as it makes it very difficult to read in low light conditions when it sets to the lowest level, ie it is too dark.
Anyone with the same problem? Or anyone knows if I can change the brightness scale to be brighter?
Edit: Forgot to say that both SGS2 are running on the same ROM and kernel as per my signature.
Hi , i found a bug on Nokia Lumia 800 BrightnessSetuo.
If you diseablle Automatic Brightness, and put it manual on medium or high, the three touch Buttons dont have light, only when Brigthnes is on Automatic or on Low (manaal) wrok.
I hope nokia fix these bug soon.

This is not a bug this is a fix given by nokia to increase battery performance.
I also thought it was a bug but checked the nokia forums and in the change log of the latest update it is mentioned that the bottol capacitive button keys only light up if you have ur brightness set to low or auto
My believe is that is is by design. If you're in a place dim enough to struggle to see the capacitive keys, you'll not be using med or high brightness as it will blind you.
Likewise, when you're outside and needing a higher brightness, the ambient light will easily be enough to see the capacitive keys.
I almost always have brightness on low so this change doesn't really affect me. Medium brightness hurts my eyes in darker environment. The only time I crank it up to medium is when I'm outside. Sometimes I'm even on low outside if it's not too light. I never think I will use the highest brightness setting.

blah blah blah....sorry, but you are not representative for 99% of all users. Nice for YOU that YOU prefer low brightness. But most of us users like at least medium brightness in darker areas because the AMOLED contrast and colours are bad and washed out when in low brightness mode. I want to decide myself if i have the button lights on/off with medium or bright display settings.
Finally this "update" is a reason for me not to buy the lumia 800...shame on nokia!

Neither are you.
Did I say you have to use what I use? No. I simply stated my personal preference. No need to jump all over me. Calm down.
Have you guys tried Auto brightness?
It goes all the way to minimum brightness if you use the phone in the dark.
The bottom buttons are lit up too.
I tried out the auto brightness for the first time today. Seems to work well. It places itself in between low/mid brightness in an ordinary lit room which is fine for me. And as you say the bottom buttons are always lit even if the brightness goes up to full strenght.
Think I'm gonna use auto brightness a bit more and see if it behaves good at all times.
Hi guys
Can someone help me out understand something? When I bought the pace I really was not aware that it had such a low resolution when the watch was not active. I know it uses a transreflective LCD.
I understand that amoled screens waste more battery for lighter colors because black does not turn on any pixels.
LCDs on the other hand waste more battery regardless of color because it is the backlight that consumes battery right?
What about this transreflective LCD? I don't understand why the watch uses an 8 bit color pallet on the lockscreen and why does this save battery? Shouldn't the backlight be the only thing that consumes more battery? If it is just displaying and image (whether it is high or low resolution), shouldn't the battery consumption be the same for both?
Can someone clarify this for me? I tried searching but could not find anything..
Transflective mode reflects ambient light without using the back light hence the name.

I know that, but that's not what I asked. On traditional LCDs it is the backlight that consumes battery regardless of the resolution correct? On transflective screens, whether the backlight is active or not, why does the watch switch to low resolution on lockscreen and why does that affect battery? Because on traditional LCDs the resolution displayed does not affect battery right?
I don't think it switches to low resolution (otherwise small text would become unreadable which clearly is not the case) . It's just colors looking washed out because now it's only reflecting light.

I don't know it it switches to low resolution but from what i read it changes to an 8-bit color pallet, that is why it looks "low quality". What I wanted to know is why does that save battery since traditional LCDs don't have this issue..
This interested me as well and I found out it uses a MiP (memory-in-pixel) transflective LCD display (LPM013M091A). I haven't done much research on how exactly it saves power between those two modes but basically it's a memory limitation in a display itself so it switches between 8 or 262k color palette. As I understand it's not 8-bit color but actually just 8 colors in low power so that's why it only looks like low resolution.

I think it just uses the 8 color mode to improve contrast and be more readable in low light as the background light is off...
I don't think so. This is just how MiP displays work. They save power similarly to e-paper displays like the ones used in Pebble watches.
According to specifications in MiP mode (8 colors) the consumption is 0.8mW and in Normal Driving mode (262k colors) 9mW for still image and 13mW for moving image and backlight is unrelated and separate from display modes and contrast is the same but as I understand in MiP mode it can only display the maximum intensity pixel colors so it may look sometimes (depending on a watchface and ambient light) that contrast only seems better.
There are also MiP only mode displays as well. The one used in this watch is a hybrid type and it's just a hardware limitation in a display itself for these low power consumption LCDs.
Also maybe it's good to keep in mind that these also suffer from burn-ins if the same image is displayed for prolonged time so it might be prudent to change watchfaces from time to time.

Great info, thanks. But why 8 colors mode would use less power than 262k colors if it's the same resolution? Could you please link to the source of the power consumption in both color modes? TIA
EDIT: I've found this: http://www.j-display.com/product/pdf/Datasheet/6LPM013M091A_specification_ver03.pdf
So it seems that they are two completely different modes: MiP with 8 colors and transflective with 262k colors.
Yea, that's the display technical specifications. This is where I got the power consumption modes:

Auto brightness in stock miui is too bad in low light conditions. Will installing custom kernel help to solve this issue or not?
If so, can you suggest me the suitable kernel?
Define too bad... Too bright or too dimmed?

dimmed. because of that you need to adjust the default degree of auto brightness in low light conditions manually.
Dimmed comparingly to what? To your ex phone? When I bought Pocophone it is considerably more dimmed than my ex p8 lite but in fact I think this is much more healthfull for the eye and I am pretty sure it is designed that way o purpose, so this doesn't make it bad... Probably our/yours perceptions are bad. Be generous to your eyes.
Hi all,
I would like to get some feedback on the AMOLED display quality in regards to uniformity when displaying a grey screen?
Did Samsung improve anything here or do the AMOLEDs still have clouding issues and the displays are not really uniform?
I have a Tab S3 and Tab S4 both with some clouding visible especially when displaying grey and dark grey.
Thanx in advance,
am
From what I have seen the AMOLED display on the SGTS7+ is actually pretty good for watching videos, the colors are excellent and so are the blacks.
It's an excellent display, as long as you use it over 30% brightness
As soon as you dive under 30%, it's a color-calibration sh**show, with a huge green tint issue (pretty much the same thing for any high-refresh rate displays of 2020. This issue was fixed by the following generation of displays, with the help of LTPO technonology)
I use it 5-6h per day as laptop replacement, and it's a blast during day time. But as soon as I want to watch movie at night time, the green tint forces me to push the brightness higher than my eyes wished.
The severity of the green tint will vary from one unit to another, but no one is spared.
