Pixel 4 vs Pixel 5 light sensor (Adaptive Brightness) - Google Pixel 5 Questions & Answers

Hi
I noticed that my Pixel 5, barely changes the brightness in low to medium light. (unlike my previous Pixel 4).
It changes the brightness when the light changes are big. Like jumping from a dark room, to a bright room.
But doesn't change the brightness when changes are small. Like, a dim room in the morning vs a dim room in the night. (scenarios like from 1% to 35%~ ).
So today I compared both light sensors and the Pixel 5 has different values. Then I opened "DevCheck", went to Sensors, then LIGHT and I started rotating both phones together and the Pixel 4 changes constantly but the Pixel 5 it just jumps abruptly (see below screenshots).
Is anybody having similar behavior with Adaptive Brightness?
Is your sensor behaving also like mine?

Edit: I also noticed that the Pixel 4 in a dark room reaches 0.0X (and different values between 0.0X and 1.0X) while the Pixel 5 in the same dark room reaches 1.0X.
I hope this is not a faulty sensor in my device. (So I don't have to go through RMA).
Thanks!

Mine also does this, although I havn't noticed too much of a change only coming from a Pixel 2XL.
Is it a limitation due to where the light sensor is placed?I'm assuming it's under the display (near the proximity sensor).

I believe this is just another contra of having the stuff under the display.
However, maybe Google just needs to improve the drivers to make it work better in dark rooms.
Personally my issue is that when I need 1% brightness, phone is still like at 20%-30% brightness and vice versa.

I don't think mine responds at all. Coming from a pixel 2xl which seemed loads better. Also my auto rotate has stopped working. Google are sending out a replacement, not good for a 2 week old phone. I'll see how the new one lasts but I'm already thinking about getting a refund and trying something else

Okay, viewing my own attachment picture from my computer right now and it looks nothing wrong :crying:. So this is screen problem, not the display, so screen capture is useless...
Try taking a picture of the screen with a camera.
Are you meaning like an image retention issue (where previous screens are still "showing through" what's currently being displayed?
(For example, you'd see a faint image of your homescreen when in the Settings panel)
Sorry for the late reply, been too worried about not able to get my RMA...

I did try to take some pictures with my phone camera, but the screen had too much reflection that it's hard to tell from the pictures.
However, I did found Androidpolice had a good report on it with same issue and they were having hard time taking the pictures too

Yes, I believe is the retention issue and worse. My screen got worse each day before RMA came. Screen is pretty much in a VERY BRIGHT LIGHT ( I wouldn't even call it color white because it's really just shinny light) stage before I even unlock the screen. All the light seems to begin to go away after about 10-15 mins of screen use time, then the display will only showing some few "ghost" problem between screen to screen. Maybe this something to do with IPS been too cold? Need a warm start like my old car? lol..j/k
I did made a video of it on that first night it happen, hopefully it will provide some kind of idea how it looks like.

So I called Google on 7/29 for RMA, and got my replacement on 8/2. So far crossing my finger on the second Nexus 7 from Google.....Thanks.

It is normal when wake up.
nobody ? ??
increase your brightness ?
it is not solve problem when i increase brightness.
it has red colour background, i can set many colours but can not set white colour. Maybe the back-lit change from white to red.
Are you using a custom face? if so, change to one of the built-in watch faces from LG, or just try a few different watch faces in general and see what happens.
I'm not sure (because I don't know what watchface you're using) but it definitely looks like your screen is defective.
Now, the screen is death
I have nearly the same problem. It's been this way for about three months. I did a factory reset three times. The screen looks fine in normal mode, but when it dims, it flashes the dimmed color for half a second, then dims dark to red. Mine appears darker. I can't see it in the daylight at all.
mine just started the same thing :/ do i need a new smartwatch ALREADY?
kay so its gotten much worse, it seems to be caused by not enough power tothe screen, it seems to get worse when it attempts white
Hi,
Can we have more informations please ??
like : did you used Stock Watchfaces, if not which one before the problem etc...
just got it back from LG, the note says:
replacement case
replacement ic/pa/filter
does anyone know what that means?
How do we get service on this watch? I can't take it back to the original store because it was in another state and I'm tired of living with it this way. Thanks
call LG in your state and winge.. it worked for me
btw my watch JUST started bugging out again https://www.youtube.com/watch?v=3AeJ6c65lOo

AOD screen burn possibility

Hello All,
I have bought last days a galaxy note 8 snapdragon version, but i have seen a bug (maybe is not a bug) that when using AOD enabled with infinity effect enabled (blue theme) screen on aod stays blue with stars on top and after one minute it goes completely black and shows stars and clock only, that i love it... but when phone is charging and aod enabled, the infiniy effect on aod stays always blue on top of the screen and not black with stars only. Well im wondering if is there a possibility of screen burn from static blue color for all over the night if phone stays all night in charge?
Please Note 8 USERS check and reply if you have the same problem.
Dont ask me to turn off infinity wallpaper or aod bcs i like it and i want to use it, also i am all day out so i must charge the phone over night.
Pic attached.

If you do this regularly, yes it will burn the screen. Your top part the screen will be slightly greener (yellow-red) by burning the blue rapidly.
I do not think it will damage the screen, to the naked eye it looks static, but AOD does shift pixels, to avoid this
@xda_rosh is there any way to fix it?
@winol but why it is black in normal use and blue when charging?
Anyone with Note 8 if have the same problem?
Having the AOD numbers ON is not a problem as they move around a bit. But blue gradient definitely will ruin you display. I can guarantee that. My first Note 8 came one side little brighter (blue-white). I purposely made a blue gradient and left the screen on at high brightness a couple of night. It made the screen bit even by burning that side a bit.
The strange thing is that even the samsung agents that i spoke knew nothing about this.
Is very anoying that we cant use AOD because colored theme applied to AOD will burn the screen

Something about Auto White Balance (AWB) of camera

When you read a review post on the web or watch a review video on YouTube of a certain smartphone, the reviewer will probably spend time commenting the white balance performance of the camera. But what is white balance exactly and why we need it on our smartphone camera?
White Balance
The color of the object looks different from their intrinsic color in different light environment, and white color changes the most significantly. For example, a piece of white paper looks a bit yellow under the light from a filament lamp, and looks a bit blue under the blue sky. Our powerful eyes can correct the color cast caused by different light environment, so we seldom notice the changes and feel good. Hence we can say that our eyes have the ability of Auto White Balance. Cameras need such feature as well, otherwise the pictures can look quite awful.

Adjust white balance on smartphones
When we take a phone, the smartphone camera automatically performs white balance, which we call it Auto White Balance (AWB). Most of the time, AWB works perfectly and the color of the picture looks accurately. But occasionally, it does not meet our demand precisely or we have a different from normal demand. Then we need to adjust the white balance manually in the camera APP. Below picture taken with different white balance setting show us that we can take very different photos by adjusting the parameter of white balance.
It is easy to have above different white balance setting done on our smartphone. For example, on our smartphone, open the camera APP, choose to use the Pro mode. And we can see the “AWB” logo as shown in below screenshot.

P20 Pro CLT-L29 flashlight issue

Good Day
I think I have a problem with P20 Pro CLT-L29 flashlight. I can see just one of the LEDs is working regardless of the camera settings chosen or if I use it as a torch. When I put a dark glass filter over the flashlight is clearly visible that just the right ( warm ) LED is on. The left part of the flashlight remains off. Any ideas how to test both LEDs separately? My concern is that it may be a hardware issue.
Thank you.
Hi,
In my P20 Pro, when using flashlight, only right LED is in use (looking on the back of the phone). But when I'm taking photo, both LEDs are used (but only during the last flash - taking photo; not during focusing).

Thank you for your suggestion. Unfortunately it doesn't apply to my phone. For both Photo and Pro modes during the last flash the warm LED just burns brighter.
I went to a phone store couple of days ago. The brand new P20 Pro for sale there was acting exactly like the same, so it seems that it's not an isolated case flash failure. I'm wondering if this camera was really build as 2 tone flashlight in a first place.
Honestly, I'm a bit disappointed as this model was announced as "The Camera Phone" when it came on the market.
Mystery unveiled.
I wrote to Huawei support and they got back to me today.
CLT-L29 has a single flash LED only. The information posted on phone specs sites
The 40mp and 8mp cameras are next to each other, with the single 20mp monochrome camera on its own, with a dual LED flash, and then LEICA branding.
turned to be wrong.
The white left side of the flash is not a second LED but a RGB Color Temperature Sensor according to Huawei support.
This is what I received back from them:
" Flash + RGB Color Temperature Sensor (*RGB Color temperature sensor is used to ensure the photo effect by adjusting the white balance and exposure degree according to the scene) "
Oh, that's interesting. I have never thought about that. I found some teardown photos on iFixIt and there is only one LED + sensor.

Yep, the plastic is deceiving. Looks just like dual LED flash.
Anyway. I'm happy that I don't need to claim warranty.
