Camera Flash is not white LED, its yellowish dull LED!! - Nexus 6P Q&A, Help & Troubleshooting

Hi,
Not sure if its just me, however, I tried taking a few photos in full darkness with flash on or even in low light. I realized that the flash was very dull and did not produce sharp photos as should happen when the flash is on. This phone has dual LED flash and I can still say that my Galaxy S3 with single LED flash had a better performance and produced really good photos with flash on.
The problem I see here is that the flash is kinda yellow in color while S3 had a pure white flash and that too extremely bright, however, with N6P thats not the case. Has anyone else noticed the same and is there a possible fix for the same ?

I agree, it's not that bright...
The flash on the Nexus 4 is also brighter than this one.

Yes, infact all other phones have a white light flash while this one has a yellowish flash. Even if you're using it as a flash light its evident. This is really depressing to see on an overall excellent phone, though my phone too has that ghoulish yellowish tint, but I've learned to live with it.

I agree, the LEDs are not as bright. My Nexus 5 ( 2013 ) has a stronger LED with a cold white tone while the Nexus 6p is not as bright and has indeed a warm-white tint. It´s not a huge problem though since I don´t use my phone as a torch light.

I believe when I first got it I had used it as a flashlight in a dark bedroom. When I was near the wall I could see that the two LEDs looks like they were different colors. One appeared more yellow while the other was more white. I assumed it had to do with balancing out the flash or something. I didn't really pay much attention to it because I take very few photos with flash.

The Nexus 6P (like many newer phones) has a dual LED flash. One LED is a warm white, while the other is cool white. When taking a photo, the two lights are mixed to create a color balance the camera deems appropriate to the scene. When using the flashlight it just turns them both on at a fixed brightness, resulting in a warm-ish colored light.

I really *don't* like this - there should be an option to just have the cool BRIGHT led activate when the tourch function is used

Camera Flash

When taking pictures in a dark environment, the camera flash on my EVO darn near blinds whoever I'm taking pictures of, resulting in a bunch of "I just smelled sh*t" faces. Anybody have any idea on how to maybe dim the flash without turning it off altogether?
I would really like to see an answert to this...and also to an issue with the flash that I have experienced. It seems that, with no consistency or reason that I can discern, the flash goes "blue" and results in a picture with an overall blue tint. Any ideas?
most LED flashes do it, i just deal with it
I think a better idea is to have the flash on at a low level so your subject knows where to look, and then the moment you click the flash goes 100%. My old touch pro did that but I don't know why EVO will not?
The light meter on this phone is slow, and it takes a while for the exposure to adjust to the very bright LED lighting. I Also think the WB is off on a lot of pictures as well. Lets hope HTC and Sprint fixes this because the camera and camcorder could be a LOT better than they are.
it would be nice if we could turn off one of the leds as an option which would help with close nite time pictures

2.3.3 color change

I am looking for honest opinions about the color change to the Nexus S display with the 2.3.3 update. I have heard very many people complaining and not liking the new color scheme. THis is key to whether I allow my nexus to update or not. If anybody can give me any opinions regarding this I will greatly apprectiate it. Also, what exactly was wrong with the original color scheme to begin with?
I've been lurking for a while now, but I suppose it's high time that I start contributing around here!
I think the update's colors are fine. Breaking it down, the 2.3.2 and below colors were a bit reddish in my eyes. While you couldn't tell for the most part, if you use a program like Screen Filter and get the screen to be very dim, there would be a very purple tint to the screen.
The update removed the purple tint, but a lot of people (the ones you refer to) began complaining about a yellowish tint and washed out colors. The yellowish tint is noticeable, especially when I compare white between the Nexus S and either my computer or an iPhone 3GS. In my eyes, it's not *that* yellow, and the screen overall looks better than it did pre-update. The washed out effect I really haven't noticed, though I do think that after installing netarchy's kernel, the colors do pop a little bit more.
Overall, I'm not a terribly picky person, but I do think that 2.3.3+Voodoo color looks better than 2.3.2 or stock 2.3.3.
Jeff's right. 2.3.3 stock colors aren't bad at all. I actually like it over the purplish colors of 2.3.2. Plus I think the lowest brightness levels have been darker than 2.3.2.

You can't compare your super amoled screen to a computer monitor or an iPhone. When making this kinda comparison, you should compare with another similiar galaxy s phone or N1 that doesn't have the purplish tint issue. With that being said, the reason why colors looks washed out to some after the update is because, before the update most of us was used to the grays being purple so alot of images that had this certain shade of gray would display purple. Now after the update, those images that we're used to looking at with the purplish issue are now all of a sudden displaying it's true color of grays, which causes the images to appear washed out. The update does provide the correct color calibrations. Also keep in mind the these screens are not consistently manufactured the same. So even tho the update provides the correct color calibration, the outcome still may vary depending on the condition of the manufactured screen which explains why some are experiencing extreme yellowish discoloration.

my brother bought a nexus S used few days ago. it was on 2.3.2
on high brightness, the white was perfect white " no yellow tint on it. perfect white.
however on low settings, it used to have pink tint that is more clear on gray colors.
so he updated to 2.3.3, the pink is gone. but now the screen has this " yellow " tint to it that makes the creen looks washed out. the blue not really a blue . its lighter blue, and the white on high setting is like yellow white.
however, he updated the karnel i think with one from voodoo where he can pick between 2 color profiles " forgot the name of the karnel but its in xda "
now the screen is back to how it was on 2.3.2 with its white " no yellowish" and when he pick the color profile for the low settings, the pink is also gone . no more pink on low settings and yellow on high settings. its actually perfect.
i assume if your phone has yellow issue on 2.3.2, then you are probably screwed. as there is no fix to that. the voodoo will only return the white to how it was on 2.3.2
but if your white was perfect and you have a problem with the pink, then look for the karnel, you will lose your pink plus the perfect white will come back agian

[MotoX] [2014] Purple Display at Low Brightness [Lollipop] [Amoled]

Okay so I bought a new Moto X (2014) last week In India. Everything about the phone is great. It was already on lollipop. But when I decrease the brightness to below 30-40% the display gradually becomes more and more purple. And with Adaptive Brightness on and in a dark room, it's so purple that the green and yellow shades appear grey or black. I know amoled panels have this problem at very low brightness and apparently many Nexys 6 users are also facing it. However I didn't see many complaints here in the Moto X forum.
So if you have this problem please vote in the poll above. Then I can ask them for a replacement. Thank you.
I'd later add some photos of the screen.
P.S. If you are experiencing this, please add some photos so that people can compare it with their displays.
ok i have this problem too, but when I'm in the bed and reading random news this purple display isn't disturbing me. i can feel it relax more my eyes. so i can say i take advantage from a bug
I don't think this is a bug, way easier on the eyes in the dark, perhaps some kind of a feature on AMOLED and Lollipop. The Nexus 6 has it, too, i think.
I don't know if anyone else noticed that in direct sun light, the screen goes extra bright - like indoor bright + boost?
This is not a feature. It's an issue with amoled displays. That's why Samsung limits the lowest brightness to a higher level. While Moto X seems to go way down. I just want to know if everyone's having this. Then it's okay. But if it's not everyone then there're some good amoled panels out there and we are getting the bad ones.
Yup, keep noticing this before the screen goes completely off.
It's not a "bug" with AMOLED displays, it's inherent to the way the displays work. Red LEDs use much less power than other colors so when the brightness is down low the displays looks like it has a slightly red tint to it. While Samsung does keep their best displays for themselves the lack of a red tint is not due to that but is instead due to not letting the brightness go as low on their displays.

That's what I meant. Not quite the best choice of word, I guess. But if that was the case, everyone should have had the pink tint at low brightness. Do you mean the ones who are not getting it are either lying or have Moto X's with LCD panels?

Well, only 2 out of 11 people have reported no color distortion. And remember that while you're asking "Is there a purple tint?" they're answering the question "Have you noticed a purple tint?"
What I've noticed is that when Adaptive Brightness is on, the display gets super dark and causes the purple tint. When I turn Adaptive Brightness off in a dark room, it actually completely loses the purple tint, and compared to my Galaxy Tab S 8.4 at lowest brightness, the screen is brighter than the Tab S. So I guess Motorola hasn't caught up with Samsung's display technology since my Tab S can actually get dimmer without such a dramatic color distortion - for my Moto X to get to a brightness level that dim, I need to turn on Adaptive Brightness (thus with the purple tint).
.
I wouldn't say it gets a Purple tint but rather a reddish one with adaptive light.
And I LOVE it. This way I don't have to install Lumen.CF or any other stuff. Way easier on the eyes at night and it gets reeeeeeaally dark. Just perfect!
I also love that it naturally has a lower white temperature point than other lcd/phones screens. Warmer white is cozy white.
7 votes for without purple/red tint.
People who are not seeing the tint, can you please upload a side by side photo of "your phone at lowest brightness with the adjustment bar visible" and "a white paper".

I voted for no color distortion as my display is very very good. I can tell you there is certainly a variation in displays. A few months back someone posted about being able to see color banding and such. Those of us with really good displays do not see that. I was going to order a Pure edition to replace my unlocked XT1097 but the display is so good on it I decided not to, I doubt another one will be as good. I had 5 different Moto X 2013 models and the displays varied on each of them as well. I kept the best one and my 2014 model is still quite a bit better then the best 2013 I had.

The rest of the phone in my case feels pretty solid and well built. Also I'm getting 47k+ scores on Antutu. Hence I am having second thoughts about getting it replaced.
My PE doesn't turn purple and has better whites than my AT&T branded one. The screen on that one is awful to me but I also use a G2, iPhone 6, '13 N7, no one notices but me.

After three replacements, I finally got a decent one. :laugh:
I'm pretty sure this is just a feature of the moto x2 go to Settings/Display and turn off adaptive brightness, you will see that it changes to normal

Indeed, when adaptative brightness is turned off, purple tint will not occur. However, I am not sure this is a "feature". It actually looks more like a poor implementation of auto brightness.

I use the CF Lumen app to turn down the red and green just a tad in the master mode. That makes my screen less pinkish.
I had the purple display issue in 5.0. Now I upgraded to 5.1 and the issue is gone. Colors are well balanced down to minimum available brightness.

Is your flashlight yellow or white?

My S8 has a very yellowish flashlight when compared to the one on my nexus 4, which is pure white. So I was wondering if anyone else had this problem
Not sure it's a problem
Some phone has a yellow flash compared to others. It makes the colors be more natural when taking a photo using the flash

I see. Personally, I prefer it to be white. So I was hoping somebody had an S8 with white flashlight and maybe I could get a replacement

Blue tint on screen (Amazon ver.G5plus)

Trying to be sure if it's either my device faulty or it's typical. As long as there aren't a lot of whites on the screen, it looks good.
Open Facebook or Chrome browser - or just anything with white background or lots of whites, and there is this blue tint over the white.
On max brightness it's not as bad, but if I turn on adaptive display, the darker the screen is, the more blue the whites are to a point, it's uncomfortable to read anything. Here is are some pictures what I'm talking about.
First one is a bit unfair, compared to Galaxy S7 Edge, but just look at the G5plus on the right. It's way blueish.
On the next picture, it's compared to a cheap Chinese phone (Nuu 3G) with a 720p display. Now, it may not show how blue it gets, because the brightness is on max to take the picture, but trust me, when it's halfway bright or less, it gets a lot worse with the blue.
Anyone else have this issue? Or is this the normal?
what i did was unlock the bootloader then flashed a kcal custom kernel to adjust the color. unfortunately, Moto and Amazon will not unlock Amazon edition bootloaders so that is not an option for you.
