I've tried to search around for people reporting the same issue on the nexus 4 and I haven't found anything. So I may be alone on this one...
Basically every single picture was a weird blurry area on the very left side of the picture (or upper side if on portrait mode).
There's no smudge or anything, I've triple-checked and cleaned.
I've only had it for a couple of days. The only few pictures in which I can't notice this problem is because there's a wall, or sky, on the left.
Here's a picture taken with my phone:

and here is a picture taken with ANOTHER nexus 4
I chose that grid because it becomes pretty evident.
Thoughts? Is this an autofocus problem or is the lens screwed up and I should get a replacement?
i think i might have the same problem... anyone any idea???
Camera lens misaligned maybe? In normal photography with say a lens being much larger than that in the camera, a blurry edge would usually be evidence of a misalignment (ie: the element being tilted from the plane of focus, or off centered from the 'sweet center'). But due to the extremely tiny sensor on most camera phones, something like a minor tilt or such is usually never noticed because they already have a pretty large depth of field in the focusing.
So if it's obviously not something like a smudge or scratch near the lens element, and it's always on the left side, I would probably say the actual glass element sitting in front of the sensor may be tilted (it could be like half a milimeter off and that's all it would take).
To seeing if you can do something even closer , macro-like, as tilted lens are even more obvious once the DOF (depth of field) because more narrow, especially since adding any distance between the phone which already uses a very wide lens and the subject will just increase the depth of field. (low aperture, close distance to subject = decreased depth of field).
PS: Whenever I did focus and alignment testing in the camera shop, we always used a tripod with a bubble level and a actual focusing grid on the wall, you can see examples of those grids over at dpreview on just bout any camera review.
There is not much of a lens on this camera. I think expecting corners to be as sharp as the center is unrealistic.

I took an idea out of Lifehacker and ripped out the lens from a DVD player to make a ghetto macro lens. I taped this to my HD2 and took a couple of these shots. They were grains of rice about 1mm in diameter. (Rice grains can come in huge sizes too, but these were tiny )
Photos were then touched up in Resco Photo Manager and sharpened a little in Pocket Artist. I used Photoshop on my laptop to resize the shots to exactly 604 pixels on the longest end. This ensures maximum sharpness when uploaded to Facebook... however, that step was not entirely necessary of course and I could have just sent it straight from my phone to FB or Flicker using Resco Photo Manager 7.03 (an AWESOME program!)
DOF was tiny and there was no additional lighting used apart from the camera's LED. It wasn't easy. The lens was almost touching the rice. In post processing, I had to reduce gamma and brightness and boost contrast. However, in keeping with the main goal of the project, I did all such modifications to the photo on the HD2 itself
What do you think?

Thats actually fairly impressive! Is the colour balance your choosing, or a side-effect of the HD2s camera in such proximity?
All we need now is a way to turn this macro lens into a flip-on flip-off attachment to a phone
When I say "fairly", I mean "very", btw
They look pretty damn impressive!
Can you get a close-up of your fingertip? It's always a good judge of a lens as to how clearly they can get a fingerprint.

I will try that later tonight I did have a go yesterday but didn't keep the shot... The magnification was so great though I think I could only have 5 -6 lines of my fingerprint show up....

That was the HD2... after adjusting gamma and contrast... before, there was a blueish glow to it. The rice was sitting on my black HD2 case which came with the phone
Ah I see. Still, I will have to dig out an old PC and see if I can get the lens from it and do this myself. I think with a few people working on it and sharing settings/ideas we can get a good thing going!
That's pretty damn trick. I like it!!
Simply awesome
Tested the DVP camera today with the Wide Angle and Macro lens that I got in the mail today
The Camera settings were in default except the flash. I turned it off instead of automatic.

Here's a picture of the Lenses
This shot is taken without the Wide Angel Lens
Here's the Photo taken from the same distance but with the Wide Angle Lens
and here's a close up shot without the Macro Lens
Then this one with the Macro Lens
another Macro shot
I had nothing else interesting things to use the Macro with in my room so I went over to my Vivarium and started taking pictures of my plants.
This shot was taken in a low light area of my Viv and I had the flash turned on. It's a pretty blurry shot of one of the pitchers of my pitcher plant.
Another low light setting but this time the flash was turned off.
This one's pretty cool. I took a few shots of the fruitflies hanging around a leaf.
These guys are TINY!
Moss picture
another lowlight shot of a little plant.
lowlight picture of one of my miniature orchid. I was having a hard time taking a clear picture under low lighting
fern leaf with spores all over it.
Full Tank shot of the Vivarium under default settings.
That's all I got for now! I think the lenses were worth the $20 I've spent on them.
None of these pictures were doctored. They all came straight from my DVP to my computer and uploaded them to Picasa.
Under the Picture info on Picasa though, it says the Camera name is OmniVision
was it hard to replace the lens?
no, it's a magnetic lens that goes on top of your camera lens.
You get a metal ring that you stick around your phone's camera lens. Then then lens it self is magnetic. So you just place it on the metal ring whenever you want to use it.
here's some more info here

well....
i saw this in desire thread.........
someone did a comparison in photos with backcover(battery cover) on and without it.. it there was a noticeable difference
in camera clarity.......
it was much improved with back cover removed...
i thought it should have been improved but a negligible. but it was a great difference..
tried it with nexus also and i also found a big difference.
the glass of backcover and the space between the glass and the camera reduces the camera clarity...
i guess i should remove the glass....lol
Man! Thanks for this reminder!
I've been noticing lately that focusing and picture clarity was rather lacking lately on my N1...Then seeing this thread it reminded me that I needed to clean the back-cover protective glass!
Especially for me, since I carry my N1 around "naked" (no case, no sleeve, just the bare nekked phone), it's not just the phone's screen that gets the smudges!
I totally believe that removing the protective glass pieces would improve picture clarity...But I'm not so eager to do anything about it as I'm not so confident in the camera's protection without them.
agreed and more importantly is the difference is more visible on a pc rather than yr nexus screen
yup, my cover is fairly scratched up at this point. If I'm taking a picture, I'm pulling it. Just be sure to hold the battery in place.
Can you post some pics for reference? Can you also post a pic with a legit camera of your camera window?
I've been thinking this may be true, but I haven't done any testing yet.
agreed and more importantly this.
Thanks, i tried it and the quality is better
I was skeptical, but there actually is a noticeable difference in clarity.

I confirm it does have a slight effect on the contrast and sharpness. I took the pictures with a spit-clean camera cover and one without.
http://imgur.com/a/v64nJ#5PseR
The first one is WITH THE COVER ON and the other one is with the cover taken OFF. Noticeable difference in contrast for sure.
Hi, the inside camera in my new S6 Edge+ from UAE (G928C) is misaligned Well it looks like it. I have attached a picture for your opinions. Is this a defect? So far after taking 3 or 4 pictures the quality is good as expected.

can anyone else confirm this with theirs? thanks
Mine is the same. Probably isnt supposed to be that way. Minor cosmetic issue. No,way effects functionality.

Yup. Same here.
Same here. Maybe its intentional? Either way my pics come out great so no worries....
we all have that. relax
The camera has hardware image stabilization in such the lens is supposed to be free moving. If you shake the phone you can hear it rattle. Start the camera app again and shake it, rattle is gone. This is due to a floating design that can move the lens to counter your movement so motion blur is reduced and is especially noticeable in lower light conditions when shutter speeds grow longer.

You are absolutely right. One can try shaking the camera in selfi posture and notice that camera hole alignment changes with phone positioning.
I have had this phone for three months, and have taken care of the phone very carefully. Now this random dark spot appears on the none wide angle camera in photos and videos. I haven't done anything that I can think of that would cause this other than accepting this big update on my phone a week or so ago. Anyone know if it's defective, or something else like software? This is the Canadian Rogers LG G6 version. I love this phone and just got it no long ago... I have no idea what I should do, because it ruins certain videos or pictures now. Here's a video to show what I mean, https://youtu.be/31gP0E3hmwo
Weird - did you take an extended video of the sun? Also, I'm sure you already have cleaned the camera glass many times, but when you clean it, did you look closely for anything out of the ordinary, maybe trapped between the outer glass and the inner lens?

No, I always avoid getting the sun into my camera for the fear burning the lens. Only thing I can think of my lens getting a lot of light is when taking extreme zoom in pictures of leaves that were in the sun one of those zoom in clip on lenses. Though the camera was facing down on leaves and not towards the sun.

I will have to look at the lens again when cleaning, because I didn't notice anything before.
I just did another test while looking for dust on the lens with a soft flashlight and this spot turned into something else. So confused, because I don't see anything when I look at it. Here I recorded it https://youtu.be/ujwJEvfcQ44
I think there is something between the lens and the sensor. I would send it to repair.
I've the same problem few month ago, I just shake the phone because I thought it was a dust and the dark spot disappeared

I'll trying shaking it before sending it to repair, hopefully shaking works, thanks for the ideas.
