Hello,
I'm having an annoying problem whenever I'm talking on my S3 outside, on a cold day like today. The screen turns pitch black and only the bottom menu and back touches are lit. It's not the first time. When I enter inside, the screen brightness slowly returns normal but even so, if i turn off the auto sensor, the screen brightness is ok, even outside. Somebody else having this problem ? Thanks.

Hi all,
I have a couple of issues with the my proximity sensor:
1) When I put my Ray to sleep mode, sometimes the screen doesn't turn back on, it stays black until I give it 5-10 seconds before it can be turned back on with the Power/Home button
2) This issue is related to Jelly Dream rom only, most of the times, it feels as though the proximity sensor is always ON because when I hover my finger over the proximity sensor, the screen dims and as soon as I move my finger away from the sensor, the screen goes back to normal brightness level
Help will be appreciated

Can't help you about first question, but about the second one - if the light dims when you move your finger close the place where the sensors are this is completely normal (light and proximity sensor are close to one another so you're probably blocking the light sensor and thus causing the phone the turn the brightness down).
Just got the V10 and the second screen dims after 2 or 3 seconds after turning off the main screen. Is there a way to adjust the timing when the second screen dims? The dimmed second screen is almost unreadable because it is so dim.
Ditto, the idea that this is a replacement for a notification LED is really damaged by the dimming. (It's not just me that bought the phone based on that idea, right?) What I've found so far:
With the screen brightness set to 0, the second screen dims fully a few seconds after sleeping. Icons become about as noticeable as dust reflections.
With the screen brightness set to 100, the second screen follows the ambient light sensor after sleeping. Under bright light it turns itself up to the point where it's useable.
I've been playing with all the LEDs that Light Flow sees, but at least without root, nothing has any effect. I might look through the /sys files later. We probably need to get root first to figure this out.
On auto brightness it seems to be that the device adjusts the dimmed display for the ambient lighting? It's not the easiest thing in the world to see, but it's certainly not hard for me to see what notifications I have. I really prefer this over a colored LED.
Light Flow settings
For what it's worth, here's my current setup, now that the T-Mobile H901 is rooted. This does no one without root any good, and I don't know how it would translate to similar LED managers. I've been using Light Flow since the Sapphire (MyTouch 3G).
Light Flow device settings: check direct mode, root mode, and run every command as root. The Nexus 5 force reset option is checked by default and I don't know if that's relevant (no calls yet). Everything else in the menu is unchecked.
Let Light Flow control lcd-backlight-ex.
In a notification, set that "LED" to Solid and to 255 brightness. Check Enable Mixer and App controlled flash. With that last setting, the app will reset the brightness every few seconds even if the system dimmed it due to an ambient light change.
Now I need to edit some notification icons to be big and colorful. I wonder how this will impact battery life? Now the app is going to be awake all the time.
I've noticed that today on auto brightness the second screen will increase in light but not much. It also is not as smoth of a transition as on main display. It kinda jumps up real quick..
Yes for me I've noticed on Auto brightness the second screen will dim in a dark room and if you turn off your phone while in that room then come out... The second screen is still dim.... It's like th second screen doesn't respond to the light sensors at all unless the main screen is on.

It would have been nice if lg included the capability to change the second screen settings such a brightness or text color.

Another one of many things that it would be cool to see baked into a custom stock rom. Good stuff. I wonder if Cloudyfa might come over and cook on this awhile. I have always loved his stock Roms....

Color would be cool. A classic CRT bright/lime green, for instance, would probably show up much better than the white.
We need to get on their forums with these ideas. Maybe some will get squeezed into an update
An app which turns off auto dim in case screen is off would be pretty much help. Maybe I'll develop one.
(I'm on the T-mobile variant)
I will be the 1st person to admit that my knowledge of mobile displays is limited at best (I get the difference between AMOLED and LCD, etc), but I have a curious observation. So, I'm assuming were all familiar with the light bleed issue from the 2nd screen. It is my impression that the theory behind the light bleed is that the "back light" for the second screen is off to the left side of the 2nd screen. It would appear that this is the case as that's where the light bleed comes from, and also (on my phone at least) if there's a notification it's brighter towards theft side of the screen and you can see how the brightness tapers off towards the right side.
Here's where it gets curious, although I'm sure there's an explanation. After unlocking the bootloader and flashing TWRP I booted into recovery and noticed that the 2nd screen comes in TWRP. However you would think that TWRP would be full screen on the main screen, but it isn't. The 2nd screen completes the upper right part of the TWRP full screen, the only place it's not full is to the left of the 2nd screen where the front facing cameras are. It looks absolutely seamless, like there's not really a 2nd screen at all, it's obviously lit from the back and not the side. It was too bright and even all the way across to the right side of the second screen to be lit from the side like it is when the screen is off.
Is there a "side" back light and a main back light? Why does it look so perfect in TWRP, literally like it's all one screen? I'll try and take some pics later but if any of you have TWRP flashed check it out. IMO there's something fishy here, or maybe I'm just crazy.

It really isn't a second screen, the phone would have costed maybe even double the price perhaps. One is thinking about how to keep try same resolution to be on par with the main screen, but what I think it is though in terms of it maybe being a special custom backlighting connected to an independent source along with software to then have the two screens one type of feel. I'm just giving my opinion, this phone I had to return and exchange because the notification bar backlight for to overwhelming and literally was day and nigh contrast on the strip of second screen. Now with this exchange I now have screen bleed under the ffcameras.

BINGO. There are two backlights. First is the normal backlight that lights up the entire display (there is no "second screen" - it's a single LCD panel). Then, there's the secondary backlight - a single white LED on the left edge of the "second screen." This single secondary backlight LED is injecting light through the left edge of the second screen and is not attached to the main backlight diffuser, which is why it lights the screen so unevenly. There are certain times when that secondary LED is on and when it is off. When it is on, it adds extra light near the left edge of the screen, which makes the notifications in that area brighter.
Try this. Turn on the Camera app and observe the buttons that appear on the second screen. Notice that the left-most (or bottom, if you hold it horizontally) button is NOT brighter at all? That's because the second backlight turns off when the camera app is running, and you only see the main screen backlight, which is even. Exit the camera app and you'll see the second backlight turn on and the bleed return. Open the camera app again and you'll see the bleed disappear, as the second backlight turns off.
Do another test. Hold the phone at an angle so the bleed from the second backlight is clearly visible, then go into the settings for the second screen, and turn it off while watching the left-most edge of the second screen - you'll see the "bleed" suddenly disappear, because the secondary backlight turns off (even though the main backlight is on). Turn the second screen back on while watching the left edge, and you'll see the bleed come back as the secondary backlight turns back on.
Yet another way to see it - power off the phone, then power it on while watching the left edge of the second screen. During initial boot, it will look perfectly even, no bleed, because the secondary backlight is off. But half-way through the boot process, the secondary backlight turns on, and you see "bleed."
Now, when the main screen is off, the ONLY thing lighting the second screen is the secondary backlight, so ALL you see is bleed (since the main backlight is off) which looks horrible.
The reason you don't see bleed at all in TWRP is because TWRP doesn't know that there is a second backlight and therefore it doesn't turn it on, since it doesn't know how.
To get rid of the "brighter left side" problem when the main screen is on, all LG has to do is issue a software update that turns off the secondary backlight when the main screen is on - I'm surprised they overlooked this obvious problem.
And here's the kicker - you know why you don't see the second screen bleed on the demo units in stores? Because the Retail Mode app turns the secondary backlight off, just like the camera app.

Spot on!
Hi there,
Does anybody know of a way to lower or illuminate the light of the static - back/home/show all screens - buttons? When reading my phone in a dark room, the lights are quite heavy on the eyes.
Kind regards,
Martin
Mine seem to change with the screen brightness. Do you have your ambient display turned on.

Thnx for the reply! It does indeed change simultaneously with the screen brightness, but it will always stay on. I was wondering if maybe the button lights could be turned off completely and only appear when the screen is touched for example. But I'm guessing it's not possible.
Hello from Indonesia. I'm user of Xperia X single SIM which use the newest version of Poison ROM based Nougat 7.1.1. I have a little problem like this thread https://talk.sonymobile.com/t5/Xper...sor-when-3g-4g-data-transmission/td-p/1146470 but the difference is the red light in my phone always ON both when data transmission/WiFI ON and OFF. The red light OFF when I locked this phone, and when I unlock this phone using fingerprint or press power button, suddenly the red light ON. I have the adaptive brightness screen turned off before. Anyone can fix this problem? Thank you so much for your help. Sorry for my bad English.
Turn off the auto brightness option
Turning off adaptive brightness is not working and it looks more like a feature than bug. (Proximity sensor gets active on lock screen or after data/wifi use to detect if flip cover is covering the screen or not?)
