Nexus 4 Camera Problem or something else? - Nexus 4 Q&A, Help & Troubleshooting

Today i experienced a strange problem with the Nexus 4 Camera. I took some pictures of a kid playing in the park. It was the day time around 1:30 PM and the weather was somewhat cloudy. The pictures in which the kid stood still were good but in which he was running or moving the showed strange ghosting kind of effect in them. I have attached the photographs here. Look at the face of the kid how it seems distorted. Does anybody else experienced a similar issue.
The camera settings were on Auto and HDR was enabled during the shoot.

Nothing wrong with the camera, just the setting. HDR mode shouldn't be used to capture motion. Only use it for still objects/scenery

The ghosting is normal as the phone actually takes 2 pictures at different exposure brackets. If your hand moves between shots then the algorithm will have a hard time merging them.

Yeah it's HDR that's causing it.

Right, that what i was thinking. Ghosting is quite different from the effect in these pictures. Must be HDR. i did not get time to experiment with turning it off. but i'll try again.
Thanx for the replies.

[Q] Camera Blur

Following the update, any picture I take with my camera is blurry. It doesn't matter if I keep the camera still and/or the subject is still.
Anyone else seeing this and/or have any ideas as to how to fix it?
Someone suggested holding down the shutter button for a sec before releasing it. I've tried it and notice when the sound is on it'll actually make a noise when it's focused. I hth you!!!

Yeah, my pictures were turning out well prior to the update. It could be coincidence and something else changed, but the update is the most likely culprit.
I've got the same issue. My picture quality has gone to crap in the JI6 update vs. the JFD update. They always come out blurry no matter how still I hold the camera.
On this forum others have fixed errors following the update by performing a factory reset...has anyone who had this blurry camera issue tried this? If so, did the blurriness go away?
Have you tried cleaning the plastic/glass element in front of the camera? Sometimes I get a finger smudge on it and my pictures will turn out blurry.

I second this heh you'd be surprised at how important this is. But I haven't noticed any problem, works fine for me.
I have tried cleaning it...but perhaps I need to use the right cleaning product. Any recommendations?
jesus. use your t shirt.
perhaps you accidentally set the focus mode to macro?

I have noticed that after the update, specifically the need to get a lock with the focusing square prior to taking the shot, is critical. Just tapping the shutter button to get a shot gives me blurry pictures most of the time. Not sure if its really the update or not or just me.
I have found if I push the shutter button down and hold it down until the focusing square goes green indicating a focus lock, then I can hold the camera still and compose my shot, as long as I do not change the distance between the subject and the camera, I can trigger the shutter by pulling my finger off the screen shutter button without bumping the device, I get much sharper pictures. Camera shake equals blurry. In this new high def world we demand sharpness more then ever.
In addition with all cameras, the sensor (or film in the old days) needs a certain fixed amount of light for a proper exposure. With automatic cameras the brighter the ambient light on the subject the faster the shutter speed will be. Fast shutter equals sharper focused hand held shots. If its darker the camera compensates by opening the shutter slower (longer) and raising the ISO to get the same fixed amount of light into the camera. In low light if you move even slightly the shot will be blurry and grainy from the high ISO and slower shutter.
Sorry if this is all well known "camera 101", just trying to help. This really is an exceptional point and shoot camera and over the top for a phone. I hope the update didn't jack up your cameras and a reset and/or the above tips does the trick for you guys.

Update:
After trying many different things I finally talked with TMo support and they sent me a replacement phone.
My old phone had a few additional problems that this one doesn't have, so I'm glad I did the replacement. However, the new phone also doesn't seem to be capable of taking good photos.
I don't know what I'm doing wrong, but I used to be able to take great pictures with this phone without trying, and now I go out of my way to setup the perfect situation and the pictures are still blurry.
The only thing I can think of that changed on the phone is the OTA update.
Furthermore, taking video works just fine. So it is something about the Camera software or something I'm somehow doing differently than I did during my first few months of ownership.

[Q] Line in Photos

Has anyone noticed this in their camera? You take a photo in low light and a line appears near the edges of your photo (only after you've shot it). I can consistently reproduce it. I'll get mine RMA'd, but was just wondering if it was just me or do other people have it? It doesn't show up at all in more well-lit conditions.
A couple more for Christmas
It seems like a software issue to me, making me think that maybe other people have the problem too. One of these shots shows lines on both ends
I just took a few quick photos with mine and I don't seem to be having that issue either. Have you tried restoring it first?
Weird, I get that too. Only in very dark conditions though. Not really bothered about it though tbh since low-light shooting is something I'm definitely avoiding with this camera.

Nothing seems to fix it. I've called for an RMA. It's worrisome that OverTheBelow has it too. I think everyone should check. The way I've been able to reproduce it is to have the camera take a picture of a dark area (not pitch black) and make sure either the top or bottom (whilst holding it in portrait) is completely dark. So the image you capture has to have something slightly illuminated in the middle, but the edges are black.
I just tried it on another Nexus 4 and got the same results unfortunately. Is this a common issue? Has anyone else experienced it?!!

HTC one great phone, lacks focus

I mean it in a literal sense.
If you look at the image below, youll be able to see that its a bit blurry,
I've drawn 2 black lines in the image, notice that the top and the bottom is blurry and the center is focused.
It doesnt occur alot, but it does happen and sometimes even in videos.
Any help as to why? Perhaps 4.2.2 might fix this?
I think the DOF is so narrow because the lens has a wide aperture of F2.0 which helps in low light.

Can you explain what DOF is?
Is there anyway I could fix it? You think anyone else has this problem?
"depth of field (DOF) is the distance between the nearest and farthest objects in a scene that appear acceptably sharp in an image." - (http://en.wikipedia.org/wiki/Depth_of_field)
And I don't think it's a problem. It's just how the lens is made with a large aperture to allow more light in to the image sensor.
You could try to compensate this a bit by increasing the sharpness from the camera menu.
I'd be more concerned with the poor dynamic range shown in the top of the pic. ;O)

That`s totally normal for the one, it only exposes the focus point, instead of the whole image, could htc not have given us a choice

Well that sucks. One of the reasons I bought this phone was for the camera.
Do you know anyway I could fix this? or atleast minimize it?
The problem is when the image contains both dark and bright areas, if you focus on the bright, the dark areas will be underexposed and if you focus on the dark the bright areas will be overexposed, you need to find an area to focus on that will give you an average exposure for the entire image.
I have the same problem, but some photo`s are amazing and some are utter crap.
Try using hdr mode, it takes multiple images at different exposure levels and then integrates them into one photo, but you need to keep the phone very steady, hopefully HTC will fix this problem.

Mine does this as well. Easiest fix I've come across is just tapping on the screen in the area you want focused...it seems to hold focus better after the first time and the photos look a lot better.
Problem is, I generally forget about this until after the first picture is taken without it. So it's a process for sure.

Has anybody tried some other camera apps from the play store, maybe we can find one that exposes correctly, i wish the one had my nikon`s matrix metering

I bought this Camera Zoom FX app for £0.50p on sale that i never used, i think it`s about time i tried it.

Mine is the same way. Wasn't bashing the camera was just giving my first impression of the pic posted. I think the camera is excellent for a phone. Small sensor and tiny optics will only go so far. This device is fantastic as an overall package.

The sensor is great for a phone camera, but the software that does the exposure is very very poor or am i missing something???

You rack focus

Why are all you guys saying this is normal? Either you have defective phones or you don't know how to take pictures! ... The only time my One does this is when I use touch to focus on Macro mode. I have taken hundreds of pictures and no pictures look like yours unless I wanted them to.
Agreed. The picture in the OP looks like an issue with OIS, not depth of field.
If it was a one time thing then this thread doesn't need to exist. If it happens a lot the phone needs to be replaced.

Well its not a repetitive condition but occurs once in a while. Even in videos.
Try camera fv-5 from playstore. DSLR style camera app with multiple metering modes.

I do think it's a flaw in the camera software that exposure and focus can't be decoupled. I LOVE the shallow depth of field but can't use it property because touching-to-focus blows out highlights.

Most of these comments come from people who have no idea what they're talking about.
Your phone is perfect. Nothing wrong with it. All you did was tap to focus on the middle of the picture.
This did 2 things.
1. It will FOCUS on the center of the pic. Other areas will be blurred. Hence the term, focus. That's how cameras work.
2. The exposure was adjusted to where you focused it to. What does that mean?
If you focused on a light area the camera will adjust the exposure to compensate. What that means is if it's light, the camera will darken the overall image. Lights become darker, farms become darker.
If the photo is focused on a dark area, the camera will adjust the photo by making the dark area brighter and the bright areas, as a result, brighter. Which is why you have super white skies.
To fix it, go to the camera settings and I think select touch to capture. But to say fix means it's a problem.
It's not.
For landscapes, use landscape mode which will focus on the entire image and bot blur. Also you can tap on the area where you want adjusted, ie brighter or darker. Blur again is only cause you focused. Don't focus on landscapes.
Photographer here. Focus on this comment and not anyone who says your phone is messed up. This is why.
Take a look at my two attached photos. One I clicked on the sky and the other I clicked on the grass. Light then dark. Can you figure out which was which and see what happened to the photo?
Note that it was overcast and cloudy. There were NO BLUE SKIES. it was grey. So the sky wasnt killed by the camera
Btw don't always use Hdr. Don't. Its not a saving grace every time. If you shoot in the sun you're shooting in the sun. Photography rule #1: DON'T.
ALWAYS USE THE SCENES WHEN YOU CAN. WHICH IS WHY THEYTE THERE AND EXIST. SLRS HAVE THEM TOO FKR A REASON!
As for the lines, panorama? Did you move too fast? That's what happens when you do - camera can't stitch properly

The black lines on the image, I DREW to show where it gets blurred (not panaroma).
You're right, but when I focus on the center, all objects in the background should get blurred right? I mean thats how the focus works. You focus on a particular subject (lets assume in the foreground) the objects in background gets blurred.
If you see the image I uploaded (in the top line) the upper part of the tree is blurred and the lower part is focused.
It doesn't work like that right?

Testing GRam and Camera

Hello Ya'll,
So I recently purchased the G2 from Verizon and a few things to note about the new GRam and updated camera with OIS. Maybe it's supposed to stutter/lag in this setting but when I play The Simpsons: Tapped Out, I see a noticeable lag when swiping across my screen in certain areas. It slows down noticeably as if it's struggling to process the graphics. I'll have to try it with more games but that's my 1st impression unfortunately.
For the camera, it seems that any sky or even upward shots with the sun just even slightly in the FOV destroys the picture. The white overtakes the picture and everything seems overexposed. If this is normal for a smartphone camera then no complaints. But just even taking a picture out my window without the sun seems washed out and I can barely make out the trees. The 1080p/60fps recording seems to suffer the same problems as the camera when indoors. The ceiling lights wash out everything and it doesn't even resemble anything close to 1080p. Maybe I have a defective unit?
If anyone else is experience this or I'm over estimating the phone's capabilities, please let me know so I can be content. Thanks in advance.

[Q] Front camera blurry?

Hi everyone,
I'm having a problem with my Samsung Galaxy S4.
The front camera is producing blurred photos, almost as if they have been automatically edited/badly Photoshoped.
Before I capture a photo, the quality looks normal.
I've made sure the lens is clean and there is no plastic covering the lens. The same happens with Instagram... quality looks fine before capturing and then the same awful result afterwards.
Any help would be great!!
Anyone?
Can you post any photos you took with the front camera?

Thanks for the reply!
Here is an example.
This is on the highest possible resolution but the same thing happens with every option. The quality is absolutely fine before I capture the photo and then, as you can see, it's as if a soft blur filter is added.
Any ideas?
Bump!
I think it's because the post procesing, which tries to reduce the noise for the cost of details (blury).
Try to take some photos in brighter enviroment.

That sounds about right.
I was trying out different apps and Snapchat captures what is on the screen and doesn't apply any after effect.
Have you got any ideas about how I can change some settings or something?

It's the camera. There's a definite lack of sharpness, and it happens on every ROM, so it's not software related.
Having the same issue.
Under good lighting, it's decent.
But under low light, or even under normal room lighting conditions, the image becomes grainy.
Even my previous S3 takes sharper and clearer images.

Exactly. I just upgraded from S2 and never had these problems. My software has just updated but with no effect.
S4 Front camera, STRANGE.
Hi,
I was having problems with my S4 trying to make an ordinarily phone call. The phone seamed sluggish and my voice did not go through once I was connected. So, I switched to hangouts. I made a video call so I was expecting to see myself in the small picture on my screen. I did see a zoomed picture in good quality? Better quality I ever had seen before! I was surprised to see a good quality zoomed picture under poor light conditions. Since I am a computer guy I realized that something is fishy so I looked for an appropriate forum to put this story in.
My question is since you are talking about a suspected software filter. Are we without our knowing it have better camera performance than we the user are allowed to use? I do not buy the ROM explanation of the problem.

S4 Front camera, STRANGE.
Hi.
I had an encounter with something, well, alarming.
I had some problems making an ordinary phone call, sluggish phone, so I switched to hangouts instead.
I made a video call to my friend. For some reason the phone had not stopped being funny. In the small picture, the one of me, I saw something I never had seen before. Instead of the expected streamed image of me I had a zoomed in version in surprisingly good quality! I could see holding my phone, S4, at 30 to 40 cm distance my mouth covering the with of the image.
Question: I looked for an appropriate forum and thread before posting. Since you are here talking about the poor picture quality of the front camera being manipulated by a software filter you might be intrigued like me about this observation I had by chance stumbled up on.
My question is whether the cameras on our phones have capabilities we are not aware of?
