[Q] What are the two circles next to the FF camera? - Verizon Samsung Galaxy S III

Noticed something strange the other night. I was in a dark room and had Waze (GPS/Nav app) open. I noticed a slight red glow coming from the leftmost circle on the top front of the phone. Almost as if it was a camera filming with night vision. When I closed Waze the red glow went away.
Just curious what those two circles to the left of the front-facing camera are. Anyone know?

Can be easily Google searched.
One is a proximity sensor (proximity to your face to turn the screen off for example ), the other an ambient light censor, to determine how bright/dim the display should be

Thanks for the info.
Wonder why the left one was glowing red. Guess it does it's best in the dark to "sense" whatever it's designed to sense.

Camera defective or is it normal

Is it just me or is the camera for this phone terrible in the dark with no flash? While taking a picture the screen starts to get all blue in the corner. Is this just an effect with the new 2.3.3 colors?

Heh that's the result of high ISO with a small image sensor. Most cell phone cameras will perform poorly in dark situations so they have to crank up the ISO to get a picture. Unfortunately this results in a ton of noise. Even dedicated compact cameras are crappy in low light... for real photography I always use my dSLR =\
Edit: Just saw this post below http://forum.xda-developers.com/showthread.php?t=1004661
Is this what you're getting? If it is, that's a bug in CM7 apparently. I'm running CM7 with netarchy 1.3.0 but I don't get thsi problem.

exactly what dinan said
with special emphasis even on normal point & shoot dedicated non-pro cameras
even the top of the line still sucks at night shots without enough ambient lights, or poor Flash flood
unfortunately dSLR cameras are too freaking chunky, heavy, and always uses special battery packs (which i hate)
I have this problem

[Q] Problem with Camera? Blue ring.

When I start the camera I get this blue ring in the center of the picture, if I take a picture it will show in the picture as well. Anyone else having this issue?
Is it a sharp blue ring, generated by software, or some kind of artifact like a light leak? Do both cameras have it? Are you using the default camera application? Can you post one of the pictures?

I guess I am the only one with this problem. I updated the firmware yesterday but it's still there, as you can see just the blue or purple ring in the center.
Is that on the shots with the other camera too?
Is it on all the shots?
If not, is there some unusual lighting for that shot?
I ask the last because as a photo guy, that looks like the type of thing that you see with internal reflections with the IR filter over the CCD under some lighting conditions, e.g. an incandescent light just out of the frame at the right angle for that shot. Again, is it on all the shots? Again, is it on the shots with the other camera too? If it is on all the shots you might have a problem, it does look like an artifact.
What you're looking at is refraction caused by light hitting from an angle (like lens flare) and bouncing around on the inside and hitting back at the inside of the glass and the glass is now acting as a backdrop. Just a wild guess. Best thing to try is to block the lens to kill the light completely. Do you still see the blue ring? If so, then it's most likely the CCD sensor.

It's on all shots and only with the back facing camera. it moves when the camera is focusing.

If it is on all the shots, you have a problem unfortunately. I just tested with mine, and you can get a very fierce IR internal reflection with a light source just out of the frame, but it isn't on all the shots of course. (see below)
Bit of a long shot, but if it moves with focusing, it might be some kind of internal light leak from the backlight. Maybe they forgot to install a little baffle or something. Turn the backlight brightness all the way down and see if that reduces it.

Anyone else notice a green / yellow tint when brightness is low?

Just like the subject says. Anyone else have this issue? When I set the brightness set to the lowest my whites have a green yellow tint to it. If I set the brightness to halfway or full it completely goes away and my whites look white.

this is just a normal trait of super amoled screens, just like how amoled have a hard time displaying whites (kills battery fast due to the display type)
I'm somewhat used to it now. Doesn't bother me at all. Plus, the peachy color isn't as hard on the eyes.

Hello, I did not experienced the change in tint because I'm slightly colorblind but there is something that disturbs me a lot, i'ts the fact that with a very low brightness, using a night mode app, on a dark or black background I can see several daker spots on the screen. I checked on a GSIII and you can also see some but it's less disturbing.
Anyone have this problem?

Is my camera defective?

Had the phone for 3 days noticed a small blue dot on camera app and other defects the first is a screenshot of the stock camera app, the second is a photo on HDR I noticed some red and white dots on this. Was wondering what the issue is.
Sent from my XT1034 using xda app-developers app
The red and white dots are iso noises overlapping themselfes which lead to significant distractions like they are in your case. Usually it's after 2 years (like it was with my Canon) so it isn't that normal. But if this problem doesn't appear in bright conditions it isn't that bad.
I'd be interested in photos in daylight. If the problem appears there, you should change your phone.

What's the little dot between camera and flash?

I noticed that since the leaks. First I thought that will be the laser focus module for LDAF, but since I got Pixel 3 on my hand, I found that was too small to be a laser focus module than any other phone has.
Besides, I tried use another camera and pointed at the back of Pixel 3 when its camera open, there's no flash coming out of that dot like my Pixel 1 did.
So what is that dot exactly? It seems like a illumination sensor but I've got no idea why we need a illumination sensor on that position. Also I can't find any explanation on Google store website.

It's a Spectral + Flicker Sensor.
Pixel 3 phones don't have the laser autofocus anymore.

On a similar note, did anyone else notice that the black model of the Pixel 2 has it's sensors hidden behind tinted glass, but the Pixel 3's are on full display behind clear glass? I wonder why they changed this. I liked the clean look of the tinted glass over the sensors.

Which sensors do you mean?
Front-facing sensors like proximity and light sensor? Or the rear sensor?
If it's for the rear, that's because Pixel 2 had IR autofocus sensors, which are themselves deep black and therefore easier to hide. The flicker sensor of Pixel 3 is not black so it will always stand out.
