Not sure if it's new but it popped up and I enabled it today.
Anyone know how efficient it is compared to OLED panel?

Ambient display on anything other than an OLED panel is waste of energy.
An OLED panel can choose to turn on only specific pixels and keep the other pixels totally off, thus saving energy.
Ambient display on OLED panels does exactly that. It merely lights up a few hundred pixels for ambient display and keeps others totally off, thus using very less power. This is the reason why OLED panels have deeper blacks. Because the pixels are kept off to depict black colour.
Our poco Panel on the other hand is a LCD display. LCD screens can either be fully on. Or fully off. This is because LCDs have a backlight to illuminate the screen as a whole as opposed to OLED panels where each LED pixel has its own light source.
Keeping the LCD screen on for such long times will drain away battery and might also affect its life. This is not bad only for the battery, but also the screen.
OLED panels barely use power while using Ambient Display. And regarding the screen, the clock keeps moving a few pixels from time to time to prevent screen burn in on an OLED panel.
In short, this is not even remotely efficient.
+1 what he said, plus your mobile will charge slowly because it has to keep whole display backlit.

It's a micro use of screen brightness, so don't affect the charging time.

I activated this feature too and it's good, only for when the cellphone it's charging, so it's ok.

I can't see the banding all the time but when I do it's very annoying. I'm going to try and post some pics today. Is it normal or can I get it fixed?
No one at all has this problem or has heard of it?
what do you mean by banding? describe it properly
in my case specifically i can see faint gray horizontal lines going across the lcd on my phone about every quarter inch. it is especially noticeable on a white screen. i emailed the ebay seller and they stated that it was normal and i would not be able to return or exchange the phone since it was sold as new. i emailed LG about it and they said it would cost anywhere from $40-$100 if it was actually a flaw. like i said in the first post, i'm going to try and get some pictures up soon (hopefully in a couple hours after i get some sleep) to graphically show what i'm talking about.
DarkKnight62, if it helps in any way: I have observed this on my screen too. The faint gray lines made me believe text lines were burned in the LCD screen, but that would have been pretty much impossible, since I don't read that much on my phone. I can only see this effect when I use the screen as a flashlight - white background and 100% luminosity and it doesn't bother me at all.

even I read a lot on my phone but I keep the brightness lower than the lowest default. so I dont have this problem.
I think, It's due to surface dithering. See our phone is not 16m colors its 256k so the colors that are missing are to calculated and displayed and that's why the horizontal band if the we set no surface dithering (custom roms mik) the banding just vanishes but the quality of display is reduced. All the linear gradient colors are no more gradient.
Sent from my LG-P500 using XDA Premium App
I do have this gray lines horizontally and vertically if you see the phone far and carefully only in white background... when its near, the lines just dissapears to my eyes, (like if they get used to the display)
"gray horizontal lines going across the lcd on my phone about every quarter inch"
I don't think he is talking abouth the lines between pixels.
can you post a picture so we can understand what are you talking about?
@DarkKnight62 I had a same problem. If you are using francos kernel (and/or roms that have it integrated) it's more visible - very noticeable on wallpapers with smooth gradients. Try switching to stock or mik_os CM7 mod 6.5.4 stable (which is great)...
@soberspine This is example:

try enabling hardware acceleration??
I got a replacement phone because the headset speaker died on my original one. I don't remember having this issue on the original phone. Can you guys take a picture of a white wall or ceiling in medium light and see if you have this problem. Otherwise I might have to see about another exchange.
Also, it seems that this has been a problem since the i9100 was introduced but I don't remember it before.

that's a light issue, not a camera issue. turn your flash on. besides, when is there ever a time that I need a picture of the ceiling?
(by the way, I checked this on 3 phones, the ones in my signature, and it does it on all 3 phones. Then I turn on my flash on the gs2 (since the other ones don't have a flash) and it goes away. in order not to get it without your flash, you have to be in more natural sunlight)
You've never taken a picture of something white before?
The ceiling is just an easy example.

I have, but if it's outside I don't get this red spot. And if it's inside, I don't get it either if I use the flash. I don't see that as a bug in the camera. My wife is a photographer. This is coming from her. It's the light.

I also just took some pictures of things around the house that are on a white background. like pictures on our wall. I took some with flash, and some without. Now it appears that this red spot for me only shows up if the picture is completely white and I don't use the flash. If anything else is in the picture, it's gone - with or without the flash. Seems like a non-issue to me.
Read up on how to do a white balance for your camera.
As you go further out from the optical center of the camera, the angle which the light makes with the normal to the detector increases. This in turn means that, toward the edges, there's more chance that a light ray will travel through more than one of the colour filters, resulting in a color shift at the edges.
Here, it looks as though the camera white-balance has fixed a colour shift around the edges, at the expense of the center shifted to pink.
Phrases to google if you're interested: "pixel crosstalk", "bayer filter", CFA.
All smaller imagers are prone to this; they're simply too short for the optics to be close to telecentric (i.e. all rays hit detector at 90°). In a scene where there's a better range of colour and lighting, you likely wouldn't notice any problem at all. If you do, then cell-phone cameras aren't for you

Not sure what is wrong with my Z2, but there seems to be some random bright spots on the screen (most notable with white or light grey background, eg in messages, etc).. The cluster is about 2mm in diameter and in the lower left of the screen.
Anyone else experiencing random bright spots (not dead/stuck pixels) on screen? Is this normal?

Never happens. you should get the exchange
Friend of mine has same problem, i think its due to overheating because he has the spots at exactly same place and its where the phone heats up most.

Hey guys, I have a wondefoo PX-5 Android 8.0 Headunit.
I'm pretty much satisfied with it but as I live in a very warm and sunny country, I almost can't see anything on my headunit as it's simply isn't bright enough.
The brightness is set to the maximum, and i've tried the trick with the "reverse camera brightness" which didn't help at all.
I started this thread on the hardware development as i'm sure it's a hardware "problem", and not software related.
Is there any fix to my issue? Even a paid one like an upgraded panel or something like that.
It hurts too much to "throw away" a 350$ headunit which is OEM look to my car.
Thanks, in advanced.
Try to tint your windows to dim down the light on your car.

If you can take some detailed internal pictures of your unit and lcd panel board, I might be able to suggest increasing the brightness potentiometer (if available.)

The sad part is that my windows are tinted, 85% on the back, 65% on the front, almost doesn't help at all.

LOL, thank you for trying to help, i hope i can take apart the unit tommorow and upload some pictures.
Will quote you again when I have the pictures.
Mine is also a bit dim on bright sunny days, would be good if there is an adjustable potentiometer on the board. I just had my head unit out today, wish I read this before. My unit is has a 8" IPS screen.

One thing I have noticed is that there is a gap between the glass and the screen, its about 2mm at a guess. I have got a few specs of dust in there already, I don’t know if it makes a difference on how bright the screen looks in sunlight, my phone screen is laminated to the glass and looks brighter.
Turning my headlights off made the brightness increase a lot.
On many LG devices, there is "kcal" settings to tune the display to eliminate screen burn.
Here's a good example:- https://forum.xda-developers.com/t/...ontrast-and-also-get-rid-of-ghosting.3653992/
I cannot find any alternative or anything similar on the S8 or S9 forums which is strange considering burn in is a big issue on our devices too.
My question is, why is there no similar cure, what am I missing?, Or have I not being look hard enough?
TIA

The OLED pixels are failing. The calibration and color accuracy as well. Since blue pixels die first any compensation be limited and you would lose color/gamma calibration. The blue pixel output is already near its max when new compared to the other pixel colors.
Red pixels generally have the longest lifespan. No way you can accurately color calibrate one of these display by eye.
Once an OLED display is degraded only a new display will really fix it.
The only thing you can do is reduce the wear by not using in direct sunlight. Use manual brightness control and keep below 50%. Use max brightness for seconds not minutes. Use dark mode and get rid of the notification icons at the top. Use dark wallpaper and red or darker icon packs. This N10+ has over 8k hours on it. No detectable display damage or degradation.
Limit exposure to sunlight and excessive temperatures including during storage.
A hot running phone is burning both the battery and display. Correct the cause of excessive power consumption.
OLEDs are very susceptible to water damage; keep water away from phones even if ip68 rated.
My N10+ AMOLED conservation management strategy. So far it remains in excellent condition even though it's been heavily used daily almost every day for 3 years. I slightly rotate the static homepage icons every month or so. Newer Samsung's incorporate pixel shifting as well.
