Hi everyone, just a few minutes ago i was looking for a completely black wallpaper and it came to my mind to just put my finger over the camera and take a pic, as soon as i put my finger over the lens i saw a few red and blue spots on the screen...i then put it over a black cloth and i could still see the red and blue dots(look like dead pixels but on the sensor?) its best visible when camera is set to 8mp. I am just wondering if this is normal or if i have a faulty camera..the dots dissapear as soon as there is some light i will post a pic in a sec. Please can anyone test it out by turning on the cam set to 8mp and put your finger over the lens so its completely dark wait a bit ( 30-40sec) and look at the screen.
Edit: Also when you put the exposure to max you can see it even better.
Did a little research and it is called a hot pixels.
Hi,
At 1st excuse my english please!
You dont need to be afraid of this, this is totaly normal an youre camera is ok!
The sensor generate colors from RGB (red, green and blue) and what you see there is no more then the try of the sensor to put colors in the dark!

Yes but they are on the same spot every time and they are flickering, the only way you can notice it is in a dark room and when you put somthing over the lens so its completely dark then i get flickering hot pixels on the same spots. Please can anyone else try this and let me know if you see it on the display/viewfinder.
A lot of sensors can suffer from that, that's why normal cameras offer pixel mapping to disable hot pixels. Unless you see those spots show up in final images I would say don't worry about.
It does show on the final picture. That is why im asking people to check if they have same thing.. if every one has it i wouldnt worry about it but if not i will go exchange it while i can. Its bright flickering white, red and blue dots. Looks exactly like a stuck pixel and not the rgb noise ones that are visible on the whole screen.

Hi,
I found an explanation for this:
The CCD-Sensor interprets residual voltage (<----Hope the right word! ) as brightness information what results in those colored spots!
As I said, its totaly normal!

If you take a picture in a dark room, the camera will boost the gain in order to try to take a decent picture. It will boost the gain until it sees enough content in the image. The darker the room, the more the gain will be boosted.
By covering the lens youve removed all of the light. The camera is therefore boosting the gain as much as it can until it's picking up what is effectively noise in a few of the pixels (some will always be more noisy than others). This wont have any noticable effect on a picture taken at normal light levels.
Thank you everyone for the explanation

I actually noticed this, too. I thought I had a dead/hot pixel on the screen, but it only appears when it's on viewfinder mode. It doesn't really appear in the image taken itself (or maybe I just don't notice) so I never really minded it after the initial discovery. Glad to know this is just normal
I'm noticing this too.
except differently, i'm not seeing individual spots, i'm seeing hair-like artifacts.

any suggestions?
Hmm that looks really bad.. did you solve it?
You will have to send the phone where you bought, I think it's a manufacturer's faulty
The other day I noticed that my once stock white colored notification LED was acting strangely. It now is multicolored and seems to have a slight flicker when it goes off. I went through Samsung US support steps, removed apps, then full factory reset. Still same problem. I installed Light Flow and tested all colors. Most work but still with a bit of a flicker. White is not working. It displays in three colors, yellow pink and green/blue? I suppose my LED has broken. Has this happened to anyone else? Is there a solution? Samsung US will not support the repair as it is an international GSM phone.
Thank you.

Yeah white isn't really white, its a combination of three colors. Its normal.. no biggie
Well mine is also like that..

I have had my phone since January and it was always a white notification. My old Nexus One was also always a plain white notification. I am pretty sure thats what stock Android intends it to be. The multicolored just started. Either way Light Flow when set to White should display a white notification but it cannot. I am almost certain my LED is defective. Anyone else?

As proved by Newton:
White light is the effect of combining the visible colors of light in suitable proportions (the same present in solar light).

Ok, so... no help here. Thanks anyway, guys.
I sure wish my LED could be fixed. <head down>
Everything you describe is normal.
You probably just never noticed it before.
I actually did notice it and that is why I have posted here. The notification light is supposed to be white. Not multicolored. I know this phone like the back of my hand. The led has changed.
Mine has been like exactly what you've described on both Nexus' that I've owned.

It's a tri-colored LED (red, green, blue).
It displays different colors by mixing those 3 primary colors.
To get white, it mixes all 3.
The 3 LED's aren't close enough together, so around the edges you'll see the individual colors, but in the center it will appear white.
At certain distances/angles/lighting conditions, it can appear almost fully white.
http://www.youtube.com/watch?v=nDrYDjXThLc
If you insist that it was pure white before, then somehow you had a white LED and it has transformed into a RGB LED.
I'm pretty sure no Galaxy Nexus's were shipped with a white LED, and certainly not ones that can transform.
AFAIK
The notification LED at the bottom of the phone has always been a 3 color LED. Red, green and blue. To get white it turns on all 3. Other colors are variations on a theme.
Thank you, terryhau.
My notification light does not look like it does in that video. It is now mostly pink with a green hue no the bottom portion and a purple/blue color in the top left hand portion. It DID NOT used to be like this.
I guess I need to post a pic somehow.
Maybe something like an update or .apk has changed the behavior of the LEDs like reduced the output which would explain why you now see all 3 colors instead of white.

I did a full factory reset hoping that may be the case. No luck. This hasn't happened to anyone else?

The video shows that it is not pure white, but a mixture of colors. Kind of hard to see because of the bad camera.

Yes. And in the video it shows what my led looked like about three days ago. It no longer displays that way. Now the three colors are glaringly obvious with a bit of a flicker as it fades out.
I am having the same issue. I have a galaxy nexus from sprint and the play store. the sprint one is perfect. all colors requiring a mix of colors show perfectly like pink, magenta, lime etc. However the play one does not. its almost like its off center so with lime you will see a bit of green and then orange on one side. Pink is slightly pink on one section then almost white every where else. Purple is purple and then has a nice section of blue on one edge.
So my question is those who have replaced your screen is the led attached to it or is it part of the speaker daughter board?
My led is darned close to white (accepting Newton's physical laws etc.). I'm thinking that if yours has changed then perhaps it's damaged, but perhaps your rom settings have (been) changed and your notification colour is now set differently (by default). What rom are you using?
I'm using CM9, which nominally allows me to have notifications in different colours for different apps. I find when I pick colours from the chooser, though I'm meant to have complete control over the colour, in reality I can get white, red, blue, green, and different rotations of rainbows.
Clarification: when I say I can get 'red, blue, and green', I mean properly: I get a solid circle of whichever one of those colours I'm aiming for. But anything else (e.g. yellow, orange, cyan, magenta, lilac, etc.) will be a the chosen colour in a small part of the circle, and an array of all the other colours elsewhere in the rest of the circle.
i can get all those colors too... but only on a portion of the window. white will show green, blue and pink on the side.. but not just around the edges. I think this is what the OP was talking about. I honestly do not think its a software issue as i am running lightflow on both of my nexus's and one is has run cm9 and AOKP witht he same results. It has to be a hardware issue. So if any one can answer this, is the LED attached to the screen or the lower speaker daughter board?
Is anyone else having a issue when they take photo's that in very bright white area's there is a bright pink color? It has now happened with two sets of pictures I have taken, One picture that has the sun in it actually has a dark pink dot right where the sun is... Is this a setting, common or should I take my phone back? the phone is only a couple days old

Lens flare? (Very common) but the colour is something like purple...
Can you show us a picture?
Sent from from my LG-D855
I've seen cameras in the past that exhibited a pink tone in the centre of the image. My G4 does this too, though it is only noticeable in low light. For example if I take a photo of the grey of my cord trousers in low light the very centre of the image will have an obvious pink tint. If I take a photo in average to normal light it's not visible.
Does anyone else have this issue? Mine is an O2 UK phone, brown leather back.
The same photos taken on my S6 have no tint at all.
it looks like a faulty phone ,-, try to get a replacement for it
I've just taken it back. Might wait till I can get it for a better price for the time being, especially now I've got it out of my system
I'm wondering if the pink you're seeing in your low light pics could possibly be the infrared auto focus? It could be that the camera snaps the photo b4 the light goes out. That would explain why you see it in low light photos only.
You cannot see infrared light with your naked eyes, but a cell phone camera can. Have a friend watch you through another cell phone or camcorder as they stand in front of you, while you snap a photo of them. Tell them to look for a flickering red light coming from your camera.
If that's the case, it can be fixed with a software update. The light needs to go out b4 the shutter opens.

I can't remember if the G4 has manual focus, but if it does, try using it for the same test. Maybe the infrared light won't come on and the pink will not show up.

Already considered that idea but the simple test was to cover the IR port up with my finger. It still showed up. Thanks anyway
Um, I don't think the camera uses that IR port. That is for controlling your TV.
For example, many smartphones do not have an IR port, yet they have auto focus. Try what I suggested b4 dismissing it. At least try taking a pic of yourself in front of a mirror. The pic should not catch the red IR light. If it does, there's some kind of timing issue.

I mean the IR port on the back, not the top! The one that blinks. I've tried covering all the sensors and there's still a pink tint.
Think your phone is a broke one, call you agent and get a new one

Has this been resolved by a replacement? I have the same issue with the pink tint/hue in the camera and I have the T-Mobile 811. I'm wondering if others have the same issue
Reminds me of the pink tint issue with the M7s. Did you feel any heat around the lens area?
In the case of the M7 it was crappy heat issues. If this happens again on the G4, I'll be getting rid of this real quick
The phone was cool and it still showed. I don't think is the heat because when I took pictures outside there was no pink tint. It's on low light conditions that it happens. I also had an issue with random dimming erratically with the auto brightness off. I did a warranty exchange and getting it tomorrow. I am hoping it doesn't have the same issues.
Got the replacement by and still has the pink center hue in the camera. This is bs. I believe people have this issue and they don't realize it. This can't be a coincidence. I don't even know what to do now. I can't return the phone since I'm past the return period.
I had the same nagging opinion with my first LG G4. I tried comparing it to the LG in my T-Mobile store but it was hard to replicate.
In the end, I replaced it for a different issue. There is still a pinkish hue near the center in some photos, particularly in lower lighting, though maybe a little better than the first (could be placebo effect)? I'm satisfied in it being just a quirk of this phone under some conditions.
Take a look at the "Post your LG photos" thread. Post some of your photos here or on that thread.
Not happy with the replacement. I still have the pink center. You definitely notice it on a white background . The crappy part is when to take video or pictures, the pink shows up. I used manual controls to change white balance to make the pink go away but it becomes way too white and unnatural. I'm going to open up a thread in the T-mobile section. I'm also going to contact LG and see what nonsense they are going to spew.
That's not pink, it's magenta, tmobiles signature colour.
If i remember correctly, lots of Xperia z3 users had the exact same issue, maybe they found a solution that can be transferred over to the g4?
There is a thread about green spots appearing in pictures for some people.
It seems that the green spots do not appear in the actual RAW (DNG) files themselves. Meaning that the green was not captured by the image sensor, and was instead added during the image processing that created the JPG.
Note that you will likely need to pull the DNG over to a computer and view it in appropriate software that can display DNG files (UFRaw is free). You will still see it on the screen/gallery on the phone, as those are showing the JPG.
Please try taking a picture in Manual, with JPG+DNG output, and check if the DNG shows the pink.
Edit: Other thread, about the green spots issue:
LG G4 green spot appearing in photos
It has nothing to do with the M7 purple tint thingy, this is something I saw in numerous old phones I had, mainly Sony Ericsson ones and perhaps Desire HD. Any white background(like walls) indoors will give the pink spot on older phones, I wonder how it's showing on G4
i tested and verified this pink spot in same conditions 10 minutes ago. lots of z3s also have the same problem afaik. i m starting to guess this problem originates from the lovely sony lenses. does anyone know which lens lg camera uses?

Hi all,
Had my Pixel for a few days now and noticed what I thought was a new gradient in the background of posts in the XDA labs app, I checked the screen using one of the grey test colours and found that I'm getting a dark cloud over the bottom right hand side of my screen. I tried taking a photo with my old phone (Moto X Pure) but the camera isn't good enough at low light for it to show up, I'll try and get a photo with my DSLR when I'm back from work later today. In the mean time some quick googling has shown it's very similar to the "Dirty Screen Effect" described here: http://www.rtings.com/tv/tests/picture-quality/gray-uniformity-dirty-screen-effect-dse
Had anyone else noticed this? Do you think Google would RMA it? I've not really been bothered by the blue shift on my device so I'm slightly concerned that I might end up with a worse replacement if I do send it back
Cheers
Michael
It's a tough call, you have to ask yourself if you can live with it or not. Does it show up a lot during normal usage? Or is it just with the XDA labs app and similar applications in a low light setting with your brightness turned to like 0-10%? Or if you can see it at all times regardless of brightness settings you can contact Google tell them of the screen issue and get a RMA. Check out the replacement and compare the blue shift to your current and see if it also has the same issue as your current device. If it's better in both regards send it back, if the blue shift is a bit worse on the one and you can tolerate it and it doesn't have the bad back light uniformity you could keep it. That's what I would do personally, best of luck!
Yes, I have a similar issue. My first device had severe blue tint at any angle and Google would not replace so I returned and and reordered. The second device had only slight blue tint and is not an issue but of course has the uneven grays. The right side of the screen is much darker and there is also a dark spot around the sim tray area on the left side. I sent Google pictures and they are sending a replacement. It's only noticable in low light, looks fine at higher brightness though.
Ah I didn't realize they sent you the replacement first. That makes it a much easier decision. I'll still try and add a photo of it in the OP later today but RMA seems like the best choice. It's noticeable at lower backlight brightness and since it's winter here in the UK now the auto-brightness often drops it down to a level where it is noticeable just in normal daily use.
I get a VERY slight hint of that on a dark gray background at 5-7% brightness in a totally dark room but other than that very specific condition it's uniform otherwise.
The photo as promised unedited straight out of the camera (USB C OTG is neat). It's not quite this bad in person, if you imagine the light grey is the same shade as the dark grey in this image and the dark grey as being almost black then you get the idea, but it does show the difference between the two and it is clearly visible with the naked eye in a dark room.
