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.

One of first to preorder first patch, and got my nexus 8g since last Monday. Never had and problems with it until an hour ago. Screen suddenly have dual layer overlay my entire screen. Anyone had this problem? Already try the safe mode, the problem still exist. See below screen shot. I would really hate to going through RMA with Google, hear it was pain in the ass

Here is a better shot with more black screen showing, but where did the black goes?

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.
I know that question will probably sound really dumb, but can someone tell me on the Moto X4 (Android One) what the device is that I have highlighted in red on the image of Moto X4 included this thread? Here is what I have been able to identify on the phone - selfie flash (top left), speaker (top center), "device in question" (2nd from top right - next to front camera), front camera (top right), microphone (bottom left) and fingerprint reader (bottom center). I am asking this because I am looking for a glass screen protector and none of the ones that I have found which claim to be for the Moto X4 show an opening for this device. No where online, nor even in read me guide that came with the phone can I find what this is, and most pictures online do not even show it (not even the official Moto X4 phone pics on the Motorola website, or Project Fi website show it either). I can't imagine covering up whatever this is will be a good idea and not interfere with proper function. Maybe imagers of the screen protectors are just mock photos since the Moto X4 hasn't been released when until just a few days ago and also I have noticed that the glass protectors I have found are not being released until the end of November, so maybe the manufacturers are waiting on releasing the protectors until after they officially knew what all of the punch out/openings that will be needed. Any help on identifying what this is on front of the phone would greatly appreciated.

I just figured out that 2nd from the front top right is the proximity sensor. Glad that is cleared up.
All the screen protectors that I've seen so far have a "notch" all the way across the top from the selfie flash to the selfie camera that leaves the flash/notification LED/speaker/proximity and light sensor/camera uncovered. At the bottom, the microphone should be exposed (but some bad designs don't have an opening!) and the fingerprint reader often has a "notch" that is open at the bottom rather than completely encircled as your example above shows.
It's 100% the proximity sensor
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.
Thanks for reading my very first post! Any ideas or suggestion, please feel free to leave a comment below.
Congratulations for this first message!
This looks to me as an original contribution from you, as I couldn't find on Internet a content exactly like yours... whereas sometimes people post messages containing the same text taken from the Internet pretending it's their work...
I'm not sure if this was a side effect of the MIUI 11 update, but I've now lost the button to enable the wide angle camera.
Previously, I could see it near the shooting options, when the Photo mode was selected, but not anymore.
I also can't find the option on the camera settings.
Anyone with the same issue?
on the screen it has dots either side of the x1, it's the left hand one of those 3 dots, the x1, x2 etc...the left hand one 0.6 ultra wide
this was in normal photo mode

That's the thing, nothing is showing, not even the zoom.

i've tried all combo's to get rid of the zoom, the only thing that did was swapping it to macro...have you tried to restore to default in the settings?
There's something wrong since it's not the expected interface.
There should be a "live picture" icon just before the "star" icon.
Probably a bootleg rom or apk.
@mods Close the thread please.
Finally managed to get the icon, had to clear all data for the Camera App. That was very weird ?
Thanks everyone for the replies!

i'm running stock and have no "Live Picture"
I cleared data, finally got the point 6 wide, which is supposed to be wide.
However, it is not nearly as wide as before the update. I no longer can get a picture of the typical house when standing in front. Sides are now cut off. Placebo, for those that think this is wide angle, anymore.
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?

Pixel 5:
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
