There have been numerous discussions on XDA and elsewhere about issues with Xperia cameras, specifically what looks like flecks of dust on the images.
It was my theory that such dust would have to be directly on the CCD in order for it to appear as sharply defined as it is.
To test this theory I removed my camera and using an exacto knife and a steady hand, opened the camera to expose the CCD directly. Then using a cotton swab and some alcohol, wiped the surface of the CCD itself.
After reassembly the dust specs were still evident in the same locations.
It is my opinion based on this that it is not worth the effort to do what I did. You will be better off replacing the camera entirely. Or letting the phone slip from your hand while you are mixing a load of cement.
Possibilities:
- the flecks are under some protective surface on the CCD
- the CCD was manufactured with the flecks already there
- pixels in the makeup of the CCD have gone dead
- etc etc
I thought it a good idea to post this so someone else would benefit and not waste time with a futile effort.

I think its software related. If you go to video, point at something white so that you can see the black dots, then wobble the phone a little. You will see them jumping around on the screen as the camera tries to focus. I'm not sure what it is, but its definitely not dust.

Your images taken through camera will contain noise during bad lighting conditions.The images taken with my phone on bright sunlight are good and do not have any noise.Sony should take care of this atleast in upcoming models

Anyone else have this problem with the front camera on their Epic?
The front camera on my Epic appears to have some kind of dirt underneath the glass. It looks like some kind of white lint or haze or dust or something has gotten underneath the screen/glass and in front of the front camera. If I turn the front camera on, it looks like I'm looking through a thick fog. If I look at the front of my Epic, the front camera lens shows up as a little white dot.
I can't see any possible way of cleaning short of taking the darn thing apart.
My dilemma is that I don't use the front camera, so I don't want to go through the trouble of un-rooting my phone to take it into Sprint for a replacement (I heard they won't honor any warranty work if your phone is rooted/rom-ed). But on the other hand, maybe I'll need the front camera at some point in the future.
Any similar experiences, suggestions, remedies would be appreciated.
I think its just cause its a ****ty camera.. really though I've only used it like twice
Cd's or tapes?
The front-facing camera on other Epics are noticeably better than my own, and I can see dust/dirt/something on my front camera that is conspicuously absent on others.
Edit: there are a few youtube videos showing complete disassembly. I hate video guides, so I had ignored them previously, but they do a good job showing the details.
Only slightly improved pictures after cleaning, but worth it. It does take considerably effort and much worry to disassemble. I also did not disconnect everything the videos show (like the ribbon cables - too risky for me).
Sorry to beat this dead horse but I believe this issue is new..
When taking a photo outdoors, with a bright sky and dark subject, the bright area bleeds over into the dark and causes a hazy effect. I believe this might be due to a reflection off the chrome bezel or plastic lens cover. example: http://i.imgur.com/70oG7.jpg
Has anyone else noticed this? I've spent the past few weeks in washington/oregon with this phone and sooo many shots have been ruined this way.
Edit: I believe it is a problem with reflections off the chrome bezel and the plastic lens cover, maybe along with the lens having no hood cover as the body is so thin. Using my other hand to shade the lens while taking pictures seems to fix the issue.

could be. i've notice this as well. a few things work for me. actually wiping the lens to make sure there are no smudges that could cause reflection. also putting the cam in macro mode.
I was applying my tempered glass screen protector and after everything was done, I did a thorough check to realize that my laser sensor has hairline scratches. Will it affect the focus or performance? It's my first LG phone..
Thank you in advance!
My laser appears to have a few tiny scratches as well.
Highly doubt it will hurt anything. My g3 laser was scratched up and it seemed fine.
I was thinking of polishing the plastic and applying a film protector to get it protected. Any idea if a film would affect the focus? Thank you for the reply.

Anyone got preventive measures to prevent laser focus plastic cover from getting scratches further? Mine is quite scratched up and I'm pretty annoyed by it. I believe it won't affect the focusing speed but it's a flagship phone from LG and yet such thing happens..

The laser cover is soft, cheap plastic. Nothing you can do about it. No, it won't affect the focusing unless you put a giant gash in it that will deflect the beam. Same thing was happening on the G3. Just be careful about it.

Polish it with ABS polishing compound, then put a drop of optical hard lacuqer on it. More trouble than it's worth, IMHO.
Although LG brands it as "laser" it's nothing more than a ray of infrared shot and measured after it bounces off obstacles. So unless the emitter/receptor is REALLY weak, there will be likely no effect on the focus.
Double that with the fact that the camera uses both the "laser" and phase detection to focus, if the "laser" fails to provide focus information the phase detection will do (slower).
Think of it that way: Do you care that much about the scratches on your TV's remote infrared emitter?
Don't worry, your "laser" is fine

I don't think you really know what a laser actually is.
The whole point of the laser-assisted autofocus is to project a tightly focused, coherent beam of light shining in a single direction so that it reflects off the photo subject and nothing else. A non-laser IR diode projects light in a "cone" in all directions, which is useless for focusing the camera. It is a laser by all means, otherwise it would not work at all.
Scratching the cover might diffuse the beam slightly but only a major gash will actually impair it to the point of uselessness (since it will scatter the light in many directions).

I know very well what a laser is, thank you very much
http://www.anandtech.com/show/8062/a-closer-look-at-the-g3s-ir-laser-auto-focus-system
A "perfect" laser would be actually counter-productive, for unless you have a sort of "crosshair" on your viewfinder to mark the focusing point, you may very well have your phone focus on the tree behind your beautiful significant other, just because your subject is not in the laser's line of sight.
It is actually necessary for this concept to work that the beam is conic. Here, see this image from LG's own keynote: http://androidspin.com/wp-content/uploads/2014/05/LG-G3-Laser-Autofocus.png
If it was a super-focus laser, would they represent it as a conic, albeit very narrow, beam?
They don't need a "perfect" laser emitter to work out their concept. Granted, they need a narrow beam to avoid interference and allow an accurate measure of the scene being captured but a perfect laser beam (perfectly coherent, single direction light) would just do more harm than good. This is not used for sniper rifle or whatever, it's used for focusing on a scene.
Scratches will maybe deviate a portion of the beam a little but the majority of it, unless the window is completely buffed, will still serve its purpose. I'm strongly guessing that the way it works is: Send a burst, receive reflectionS (plural because there will be more than one) and apply some algorithm that'll define the most appropriate distance to focus on, based on the collection of durations from the receiver.
So I have a question on this topic. Since its supposed to be infrared, on a remote, you cant see anything being emitted unless you look at the emitters through a camera or something. When I have my camera on my G4 on, I can see a tiny red red light shining. Can anyone else actually see the red light being emitted? Just making sure mine's not defective.

I can see it too. Very much like you can see the IR emitter of your TV remote, except it's more focused here so even more noticable. Your device's fine
More on why we can "see" infrared in certain conditions even though it's out of the visible spectrum: http://phys.org/news/2014-12-human-eye-invisible-infrared.html
You'll notice that the "laser" is pulsing rapidly, which is the required condition to trick the eye into "seeing" the beam.
Hello,
Today when taking photos I've noticed that light sources like lightbulbs and chandeliers appear twice in photo. It's hard to describe, but attached photos should clarify what I'm talking about.
I've checked on other phone, Honor 8X and it's same.
And here's my question to you: do you observe the same behaviour, or my device is flawed?

Yes, Honor does the same. Actually I've just checked LG V30 and Huawei P10 Lite, and it's almost the same.
I'm kinda shocked I haven't noticed it before.
Can you please check on your phones?
I don't know if it's worth using warranty with my Note 10+ if it's the general issue.
I took a direct photo of my desk lamp and there's nothing wrong, I'll try again later tonight using different angles/sources.
I googled it and this problem is widely commented on:

Thank you for the link. So it seems like this can be considered "normal".
However I'm still curious what will be result of your tests. Please share what was the outcome, whether you were able to reproduce this.
It depends on the angle, sometimes you will see this, some times not, I have seen this in dedicated cameras as well
Thank you for your response.
As I'm testing it more, it seems very hard to take photo without ghost lights when not pointing straight into light source, attached few more sample files.
Maybe I'll get over it, if not I'll give it a go, and use warranty, they'll do something with this or not.
Hello,
That's amazing to see this post today, just the day i noticed exactely the same.
I noticed that when doing a video test, through windows stores (the room was in the dark, light going thru the little holes in the stores). I had exactely the same kind of little lights reproduced in the left quarter of the frame.
I thought it was due to the shape of the lens, some kind of light reflexion on it, but now i am wondering because that is the EXACT same thing as your description.
I would not send to warranty... since i had exactely the same 'problem'. I believe it is due to lens design.

I believe you have the same, but don't know how often you see these lights.
I can understand this can be seen in some conditions, but as I'm testing it more, I almost can't take any photo without it.
I've looked through YouTube reviews with some night shots and can't see it there.
Attaching last two samples, to not spam this thread, as maybe I'm now oversensitive on this
I'll go to the store today, and see what they'll say.

Went on tonight to my favorite night photography places and the full moon was the perfect source of light to look into the "ghosting" thing. It's really easy to see what's happening with the light when moving the camera around its axis. Note 10 has a rather thick glass covering/protecting the lenses and the light entering the camera is being distorted by the inner and outer surfaces of the glass plate depending on the angle of entry.
I was having really boring Sunday today so I'm glad I found something to do because of that, and I even made a little drawing using the S-Pen(love the s-pen!) to illustrate directional changes of light while entering/exiting a medium of different densities (air/glass)
We know that light will get reflected by a glass at certain degree because of different density between air and glass. Basic physics. Our camera is made of multiple layers of lens with variables angle. So if 99% of light goes through the lens, 1% get reflected. We won't see it for normal light. But if the light source is very bright, even 1% will be visible on photo.
That's my hypothesis.
Happens all the time when facing a lamp light directly, with wide and zoom lens. But seems to be less visible with ultra-wide.
This looks like an internal reflection within the camera it's self.
Internal reflections are common on multi-element lens.
You pay big bucks for coated elements and engineering to suppress this effect in pro lens.
Internal reflections can also happen between the cmos sensor and any of the internal optics.
In the case the cover element is a prime suspect.
Lol, you can thousands for a pro shooting system and you will still find this.
Given that the rear camera's sit behind a piece of glass, is it possible to protect that glass?...i'm not sure how it would affect the camera performance, but once you get a little scratch on that surface, you'll have a camera that struggles to pull focus on close objects.. thoughts? Because the area is kinda big (as opposed to the usual little camera part, it seems like it would be easier to end up with a scratch on it. It took me 5 years to end up with a tiny scratch on my lens on my old phone, but once I had it, I could hardly focus on a receipt.
You could use a Moment case. They're designed with a built-in lens mount which has the side effect of providing some protection around the lenses. It should reduce the likelihood of the lenses getting scratched.
