So, my problem is that my camera does not seem to focus an Objekt, even when I "touch " it in the camera app. It is still a bit blurry when I view the taken shot. When I look at my friends Nexus 4, colors are much better and everything is sharp. Is it possible that I have a broken camera? The settings are exactly the same...
It may be helpful to post some example shots.
1st thing to look for is to make sure that the glass covering the lens is clean. And shoot in good lighting.
Known problem, please star the issue http://code.google.com/p/android/issues/detail?id=43153&thanks=43153&ts=1359017856
AW: Bad camera focus
And the washed out colors? Max it be the fault of rev10 devices? A friend of mine said something like that
//edit
Here's a sample. If you zomm in you will see the Blurry borders. They are really annoying because when I look at the pic on a PC, I am able to notice it. Maybe it's the cameras fault or Googles fault for bad drivers and software.

It seems to me like the hardware is perfectly capable of the focal lengths to get clear focus, it's just the autofocus implementation that's broken. Is autofocus a driver level implementation? If so, would it be feasible to try and create a custom driver to at least allow for true manual focus?
There are several things that can be going on here. 1.) it ain't a great lens, so not all areas of the picture are going to be razor sharp. I see a good degree of softness in the corners.
2.) I have noticed the camera's default behavior is to use lower ISO, and longer shutter speeds in less than ideal light, making camera movement a major factor in blurry photos. If you're gonna test under less than ideal light, rig up some kind of tripod.
3.) Auto-focus algorithms decide focus based on maximum contrast. If the area of your focus reticle is over an area that has poor contrast, focus will be compromised. Low light also lowers contrast.
4.) Depth of field. It is limited with this lens. Make sure areas you are checking for focus are on/near the same plane with shots that have reasonable distance separating foreground/background objects. They all can't be in focus.
With all that said, reasonable photography skills can get pretty reasonable results from this camera, as is exhibited in the photos posted in the photo thread of the "general" forum.
It does focus, but has a small delay tho..
actually the focus on N4 is slow a little bit ..
Is there any new piece of information about the bad camera focus?
anyone else have a pink haze when capturing white objects
Hey!
I can't seem to find any samples or anyone even showing or mentioning the results of the front facing camera in any review.. From what I have seen on the z1 is that the pictures of the front facing camera are grainy like crazy if the light isn't perfect. Anyone knows if the slightly better hardware of the z2 camera gives out a better end result? Maybe anyone of you can link to some pictures on the web.
Thanks!
The front camera is just a 2mp ish camera which really all you want it for is 'selfies' which it will do the job.
From the samples I have seen Im pretty pleased with the results of the rear camera and low light pictures definately look acceptable.
Im on the LG G2 now and the camera is awesome, the pictures I take are amazing, until the light starts to fade, then it takes about 3 seconds to focus, if the object is moving its blurry and looks like a cartoon. Im just hoping the Z2 gives me the awesome pictures in daylight and ok pictures in low light which are not blured, that will do me. But as always I wont know until I test under my own uniqe conditions.

Is it possible to capture a photo in broad daylight and have it look like this? The noise is HORRIBLE! (skin correction is turned off). I dont even dare take selfie shots. The results are ALWAYS awful not matter the lighting conditions.
This is during daylight:

This is at dusk, so its not completely dark:

No one? Everyone's Note 4 takes so bad front camera pictures? Oo
bump
This is unfortunately typical of the Note 4's front camera. The module's just not quite up to snuff - it's got a tiny sensor without OIS. Sure, the optics get a bit more light in, but at the cost of stretching things near the edges.
Skin correction "helps" things a bit I guess, by blurring the skin surface so you don't see image artifacts, but it makes other things in the frame blurry.
This is very weird. The Note 3 I had before had a better front camera than the Note 4!
I took a couple of videos and the quality to me just isn't that great. This is with the UHD setting. Just isn't that clear for UHD.
I agree I had lots of noise/grain in mine. FHD60 seems a bit cleaner
This is a pic zoomed in half way. Looks awful. I bought this phone because the camera was supposed to be unreal. Is this normal or just maybe I have a bad cam?
Shot some video in a dark bar venue of a band playing. Using the main lens and manual settings, it turned out really well. The wide angle left a bit to be desired as shot but I think I have an idea for that lens. Shot with 1080 at 30fps high bit rate. Posted it in another thread over the weekend.
And at full zoom
Shot at 1080 30...

Looks as though you may have a dirty lens.
The light in the room is a give away of grease or finger prints across lens. As the ceiling light starts to chase across your shot.
Same thing can cause grainy pictures. As it effects even a camera shot the same way.
Always try cleaning the lens if the shot seems to be poor.

I've tried to clean the lens, no luck. Do u think it's the phone itself?
Did you set to record in high bit rate?
Personally, I think the camera, both video and still, is the weakest part of the phone. I am not happy with that, but will live with it until the Note 8 comes out.
And you removed protector of the camera lens?

What other settings did you use? (ISO, Shutter Speed, Bit Rate, Filters?)
I will say that it looks like you're using the digital zoom, which is always problem #1. Never use digital zoom unless you have to do so. Whoever came up with this gimmick should be dragged out into the street and hung. It just doesn't get you anything but a mess. Optical zoom is optimal. Bipedal zoom is your secondary option. Digital zoom just shouldn't be an option. It is quite literally the option you choose when you want to have some sort of shot, any shot, and you don't care about the quality of the shot. This goes for any device from a cellphone up to a DSLR.

This was shot in a very dark bar venue with mediocre stage lighting. (Strike one against getting decent footage.) ISO 3200 (Another strike against any decent footage as you're maxing out the gain on the sensor.) 1080 at 30fps so I used a shutter speed of 1/60. I used the high bit rate setting. The refocusing is me touching the screen as I couldn't tell if I had good focus since it was dark and my eyes kinda suck these days without readers. I was playing with the audio settings and had no idea how to set it for a concert so I cheated and used approximately what I found for concert settings in the HD recorder app.
Considering the conditions..... the V20 did extremely well! I could pick things out in the audio that I couldn't live in person. In person, it was just a wall of sound sometimes. The video turned out amazing for being a tiny camera sensor. The only real thing I can knock the V20 on is the video stabilization. There needs to be settings somewhere so I can turn the OIS and EIS off and on so I know if it is on or off.
Are you using the stock cam app? I don't see anything where I can change the zoom type.

Yup, stock camera app. There is no setting for changing the zoom type. If you aren't clicking the one tree/three tree buttons, then you are going through a digital zoom. Only clicking those two buttons uses purely "optical zoom" although in reality, you're just completely switching cameras. (Different sensors and different lenses which presents its own issues since the wider view uses a smaller sensor and smaller aperture while the main shooter uses a "larger" sensor and larger aperture.)
Using pinch to zoom or the zoom slider means you're going through digital zoom. So if you start at the widest setting with the wide view and start zooming, the image quality is only going to get worse until you pop over into the main imaging group. Then if you continue to zoom, the image quality will degrade again. The best quality you're ever going to get out of any single focal length imaging assembly (which is what we're technically dealing with here, two single focal length imaging assemblies) is at its native focal magnification and at its base ISO. Which the photo options says is 50 but that's not always necessarily true, I'd have to look up the native sensor ISO online to be sure.
Did an unprocessed and processed test with my v20. By far the best dynamic range of any phone camera I've worked with.

The only positive thing I found about the digital zoom on the v20 which is unique in my experience is that when you're shooting 1080p on other phones, even though it's a 4k sensor it zooms up on the post sampled 1080p frame instead of taking advantage of the 4k sensor and zooming up without any quality loss. The V20 appears to do just that and up to a point there's no fidelity loss with the digital zoom because you're sampling a smaller section of the sensor..

Don't remove that. It helps protect the glass from scratches and shatter.

Did you gain any insight to help fix your grainy pic issues? I'm having the same problem. I keep seeing people suggest to remove the plastic protector but it has cutouts for the lenses and the sensors so I don't see how that makes a difference. I'm taking pictures without any zooming but when I take a look at the results and zoom in to different parts to review, it looks horrible and grainy.

I haven't. I wouldnt take the plastic off. As you said, it has cutouts for the lens. Not impressed at all with the camera
I'm amazed at your low light video. I also thought the camera was the weak point of the phone. Guess I need to work on my manual focus skills.

For some reason the exposure on the front camera is really low. When switching back and forth from selfie mode and video mode there is a huge drop in exposure, compared to the front camera where there isn't any difference at all. Looking at all the video tests for the front camera on youtube, they all look fine in comparison. I can't tell if this is a hardware defect or if the front video camera on the axon 7 isn't that great. Anybody else have this issue?

Hi, I have the same problem at low light but it's fine at good light condition. It seems that the back camera automatically adjusts the exposure at low light, but the font camera does a bad job. However, you can manually adjust the exposure thorough the vertical slider on the right. The algorithm of Axon 7's camera sucks!
