Camera issue: pink spot in low light?

While playing with my camera at my desk in low light, I notice there was a pink spot right in the middle of the frame when shooting a blank white background. It seems like this is an issue with some Samsung phones, too (came up as suggested posts). I've never seen this before on any phone I've owned, but I'm sure it has to do with the sensor—could be a characteristic of the sensor + high ISO. I don't think it will be a real-world issue, but it bothers me to know that it exists. Anyone else notice this?

I can't even look at mine they are so bright. In fact I just looked at them for less than a second and now I see spots as I'm typing this. There might be something wrong with your unit.

Mine aren't bright either. I compared to my N4 and the N4 is clearly brighter, despite having 1 led vs 2. I don't mind the amber tint. It helps take better photos because the color temperature more closely matches the indoor lighting conditions where you're likely to use the flash.

I also feel that the Nexus flashlight isn't as bright as it could be. However, the light on my last phone was similar, and I installed an app that increased the brightness for it. It worked great, but the LED ran much hotter after that.
I suspect that the reasoning for the dimmer flashlight is to not prematurely wear out the LEDs, or degrade their performance when they're needed for camera flash.
When taking photos, the flash output is quite surprising. I don't think it's a hardware issue, rather intentional software programming that runs the flashlight at a dimmer output. As a quick flashlight, I find the N6's lights adequate.

Another blue light filter bug?

Just noticed, whilst having the display mode on AMOLED cinema and blue light filter on or off and auto brightness on.
If viewing in bright conditions with white background, example Google, the screen slightly flickers as the brightness is increased to Max ,and during the flickering goes yellow and pink momentarily, yellow- similar to blue light filter being on. This occurs regardless of blue light filter being on or off in screen settings.
Easily reproduced by placing hand on light sensor and then removing hand from light sensor when going to Max auto brightness.
Anyone else?

Reddish warm white balance on default settings

Hi. My screen is kinda red even when using cool white balance setting where as gsmarena reports the screen is blue tinted. It kinda bothers me that whites are pinkish so is it normal or is my unit faulty?

Question Tab S8 LCD blue light filter / eye care mode

Hello!
Do you also suffer from the dumb eye care / low blue light filter on the Tab S8 with LCD?
Ist there any option out there with root to change the LCD calibration and reduce the blue color channel?
Or to enable the stock android night light mode?

Welcome to XDA
Don't go too nuts over blue light. I don't use night mode anymore on my N10+, the color rendering degradation is annoying.
Increase room ambient light levels and manually adjust brightness to the minimum level needed instead.
Take a break every few minutes to look at a distance object.

You will adjust to the low blue light mode and forget about the orange tint if you enable it for all your devices Android, Windows, ... And the low blue light mode really helps to relax the eyes.
For my liking the Tab S8 LCD color temperature is far too cold. And there is no way to adjust it like you can do on the S22 in the display settings (even with no blue light filter enabled).
The low blue light mode on the S22 and Windows behaves identical and they can be adjusted to match. You won't loose by far so much image quality like on the Tab S7/8.
The correct way is to adjust the color channel equalizer of the display/gpu and not putting a transparent orange overlay on top of everything.
This stupid orange overlay is by far not the same like the real low blue light mode.
Even if you enable it at 75% the whites are still not warm and the blacks get brown so that there is no contrast left.
And at 25% you won't notice that it is enabled but also dulls the image.

Yeap.
Again I wouldn't even bother with trying to pursue this... results will be predictably suboptimal.
