Rear Camera focus issue - Galaxy S 4 Q&A, Help & Troubleshooting

Hi guys,
bought a i9500 china version here in shanghai 2 days ago and the back camera has issues. Auto focusing is pretty much non existent in indoor situations, and even when I do tap to focus multiple times to get it right, the picture turns out like it has a radial blur filter on it where the tapped area would be somewhat in focus while the rest of the image would get a gradient blur as it spreads from the focus point. Macro shots seem to be ok and doesn't have this gradient blur.
Stock chinese firmware brand new phone. Rooted and unrooted has the same issue. Anyone else experiencing this? is this firmware problem or hardware defect? Does the S4 just have a ****ty camera? Pretty disapointing for a $600+ phone...

You might try making sure your firmware/camera firmware is up to date.

lines on camera preview, and on pictures

I have just recently started noticing that when trying to take a picture or a movie that on the "preview screen" there are lines that run vertically on the screen (in portrait view) or horizontal (while in landscape view) - they run from the top of the phone to the bottom.
I have looked very carefully at both the lens on the battery cover, and the lens on the actual camera (under the cover) they appear to be very clean.
I don't remember this being this way at all, and it wouldn't really bother me too much, but my pictures and movies seem to be affected by this. when i view a picture at first it looks ok, but when I zoom in further the lines are more apparent. (especially in the corners and top/bottom)
i attached a screenshot of the preview screen that kind of shows what I'm talking about (pay attention to the bottom and top of the picture to see the lines / distortion
* This seems to have happened within the last week. (older pictures don't have the lines on them)
* Haven't installed any new apps
* Running fresh 1.1
* Reboot doesn't help.
* Wifi and GPS off and still happens
Anyone else have this experience, or even better would be if someone fixed it.

I have been running fresh 1.1 since it came out
I see what your talking about and from a photographic stand point. if it actually affects the photo when its taken and not just the preview I would say that there is something wrong with the sensor I would take it to sprint and have them check it out.
I have this same issue and it did not start until the MR release. Prior to that, the camera was pretty awesome.
I have been noticing this also and like the person above me stated... It didn't start until the MR release.
I have the same problem and I am also running Fresh 1.1. I started flashing right after I got it so I dont know if it was always like this. I have another Hero that has not been rooted, had the MR, and is taking great pictures. Tipharet and Doniiniicano, is your device rooted? and/or running a different ROM?? Sure a quick fix would be to bring it to Sprint, but I really dont want to deal with that.
if it was something to do with the MR then it is possible that they may have changed and or messed up the sensor settings.
BTW I am running Fresh 1.1 and have no problems.
This happens a lot in low light situations.. it did this on all my phones.. iphone, blackberry, Pre, Hero.. Cheap Sensors..
Im a photographer as well, and I can tell you there is a night and day difference in sensors in phones compared to regular cameras. I NEVER use my on phone Camera anymore.. because its so crappy.
night and day of course is different. However in low light situations I know for a fact that this did not start until the MR.
As far as the quality, for a phone it did not use to be that bad of a camera.

Yeah Im rooted, with fresh 1.1 but this happened before I even started flashing.
It's just high-ISO noise.
jonnythan is right. I did some research on camera noise and also found Banding noise. Banding noise is highly camera-dependent, and is noise which is introduced by the camera when it reads data from the digital sensor. Banding noise is most visible at high ISO speeds and in the shadows, or when an image has been excessively brightened. Banding noise can also increase for certain white balances, depending on camera model. So I guess if your Hero has this, it sounds like the only option is to have the device replaced and take a gamble the new one doesn't do it....or hope 2.1 fixes it <fingers crossed>

Ive never seem banding like that but hey its a possibility I guess it may be more noticeable on a camera like this than it is on a slr.
my phone was like this day one. I thought it was suppose to be like this since when I take pics I'm in low light.
Dont forget that we also only have 65K color screens. that will cause banding as well..

Camera Performance?

So I have read in a few places that the camera on the DVP isn't so hot.
Can anyone that has one comment on this?
Thanks!
http://forum.xda-developers.com/showthread.php?t=833298
It's a DVP vs HD7 thread, but OP has samples from DVP. Some people also stated the DVP camera is OK during daylight shots, its in low light environments when it starts to perform poorly.

I can back this up. With enough light, the DVP does very well. Where there is low or little light the shutter speed is way too slow to make anything come into focus.
WP7 in general, or DVP issue, the auto white balance/iso settings are pretty garbage and need to be optimized to ever be used properly. The only decent pictures I have gotten have been with all auto settings disabled.
only thing that has me a little worried about the DVP is this...
youtube.com/watch?v=FMhM3InAzwc
apparently the camera quality kinda sucks unless in direct sunlight.
Yea, this is what I suspected.
Now the question is whether it is a software issue or a much larger hardware issue.
I have a TP2 now, which doesn't have a flash but takes pretty good pics.
Although this is not a dealbreaker, it is just another chink in the big picture as I have been waffling between G2 and the DVP.
Epic fail!
After some time with the VP, I can honestly say this is the most awful 'cell phone' camera I have seen.
Yesterday I tried to take a picture of the IMEI number on the Vibrant. look at the difference... between VP and the G2.
I tried a lot of things with the VP but still nothing. I have no hope for this camera. Also However steady you hold it (even some 3 sec after the shot) you always end with a blurry unusable picture.
The only pic you can ever take is of landscape in bright sunlight.View attachment 445085

If you are not a 'compulsive' early adapter [like me ] then G2 is million times better... It's not even a close fight.
My exp with android was a few weeks with G1 and a few weeks with myTouch3G. I hated it, I always thought like they tired too hard to be like iPhone but didn't have that finesse.
Then a month back got the G2 after liking the Android on my HD2. and I'm in love. I like the whole widget approach, I like it that all that I need is on the home screens (not unlike what WM7 promises but it's not there yet). Go to the G2 forum and check the home page screen shots... no two android phone will look alike.
And there so many 'tweaking' possibility.
I checked the EXIF information of the pics taken with Venue Pro posted in this thread. Interestingly, the reported camera name wasn't branded as coming from a Dell Venue Pro (unlike the Samsung Focus which reports Camera: Samsung SGH-I917). I guess Dell forgot to change that EXIF field.
Instead we have Camera: OmniVision OV5642. This is the same sensor used in the iPhone 4's rear camera. I don't know how good the iPhone 4's camera is, but I guess this means that hardware-wise we should expect the same performance from the Venue Pro. Hopefully the current problems can still be fixed by Dell whether its software-related or just build quality issues.
Interesting observation. It also makes you wonder how they could *** it up so big time.
Can anyone confirm that the camera does in fact take blurry low light pictures? Can this be fixed with an update or is it a hardware issue?
last i heard dell was actually looking into the camera issue and settings. Hopefully they will have a fix for us
Actually I go to OmniVision's website and get a quick check. it's quite likely that it's just the sensor, excluding the camera. so you can easily answer the question of why the pics from a same DSLR can differ this much - the lenses are different. searched for pictures of IP4, DVP and Omnia 7. based on subjective comparison of the pictures, IP4's lens seems the best and Omnia 7 the worst...
Anyway, let's wait for Dell's patch.

[Q] Camera tweaking help please

Greetings all, I just got the N3 upgrading from the N2 and without doing any tweaking I am finding my the camera performance poor compared to the N2. Is there something I need to tweak? I didn't really do anything at all to the N2 and got the best camera performance I've ever had on a phone. But so far the N3 is so bad I'm considering returning it if I can't fix this somehow. And yes, I did take the protective plastic off the camera

Have you gone into settings and put it on 16 mp
This has been answered tons of times in other threads, learn to search.
Basically people complain about the camera on the Note 3 when it's actually amazing. Take it outside and take a picture and you'll have stunning quality. When it becomes darker it got a hard time since they have removed the Night Time feature and inserted another method instead. This is mostly software related issues rather than hardware.
Yes, I tried 13M, 9.6 which is what it was set on out of the box and 8M. Doesn't make a difference. But thank you for trying to help.
And BunnyPig, don't be an ahole. I DID search but I haven't found ANY threads with an issue like mine. Outdoor pictures are JUST AS BLURRY as indoor. It has nothing do do with a lack of night mode, pictures that are normal, daytime indoor ambient light pictures should not be out of focus. This camera just will not focus. After looking around I see nothing that addresses this issue anywhere. Think it may be a bad unit and hardware releated. But thanks for nothing.

There are TONS of people complaining about the same thing, I was not being an "ahole". You are complaining about a camera that's really good, if it's defect then get it replaced, you haven't given us ANY pictures nor any description on what's wrong until now. I was just making a statement on that a lot of people have complained only because lack of skills on adjusting the camera and on the overall quality. Check this link out (took me one minute to search for this!)
http://forum.xda-developers.com/showthread.php?t=2438592&highlight=share+your+best
You have a lot of decent pictures there. Some are better than others because some people know how to take pictures and how to get them to have decent quality with and without lightning. You're the being rude to me now. You can also find several solutions and explanations on how the camera works.
I just ran across the street to the Verizon store and the guys there looked at it and after 5 minutes said it's a hardware issue. Unfortunately they couldn't swap it out there because of my corporate plan so I am on the phone with Verizon and they are going to send me another one.
If the N3 needs more light than a brightly lit office or full sunlight outdoors to take a picture that is in focus then I am going back to my N2. We'll see what the new one does when it gets here.
Just for fun I installed Focus and tried that, but every time I try to take a picture with it I get an "unfortunately focus has stopped" error.

Sorry to hear that the phone was defect. Hopefully you'll be happy with the replacement they'll send.
About the Focal app, the Focal does not support the Note 3 camera yet. It'll be added in a near future.

[Q] Samsung S4 camera question

Hello,
it might be asked a lot of times, but I, personally, cant find any info on how to improve Samsung Galaxy S4's camera.
I updated my S4 from 4.2.2 to 4.3 (and regret it deeply) and found that fantastic picture quality from 4.2.2 version is poor at best with 4.3.
I tried to change ISO, picture quality to 13 and then to 9.6 MP, update camera firmware but the picture quality is still poor.
I would like to go back to 4.2.2 version but because of KNOX Warranty I'm a bit scared (still have 1.5 years of varranty).
So I would like you to ask you all for help - is it possible to get picture quality to 4.2.2 version's or maybe somehow get 4.2.2 version's camera app. I don't know, my knowledge is very limited when it comes to Android stuff.
Hope you can help me.
Sincerely,
a new member
U cant come back to 4.2.2 without void the warranty
What do you mean by poor quality? I'm on 4.3 and i've realised a lot of my pics are blurry, i just assumed i've not been holding the camera still when taking pictures but it's happening quite often. When i think about it, i don't remember it happening when i first got the phone.
edit: Here's a good example of a recent pic that has come out partially blurry, this doesn't happen on every photo and it's rarely blurry across the whole thing, notice how the image is much sharper near the bottom, and how bad it looks towards the top. I'm sure this is a software problem.

Would different camera software solve this problem (or at least help me troubleshoot?) or is this something that needs to be fixed with an updated kernel?

Camera Update (Autofocus issues etc.)

Hello,
since there are problems with the camera software, I am opening this thread to discuss your experiences and software update news.
I got my S20U Exynos variant today and straight out of the box there was an OTA (430MB) available which stated that the camera experience has been improved. It got better because I have tested it before the update but the autofocus is still "jumpy" and has problems with objects that are near to the phone. Even if i turn on the setting to adapt autofocus to the selected object in the viewer, it still jumps
EDIT: I did some tests today with my own face using the main sensor and the oversharpening / skin smoothing is gone. I tested it with HDR turned off and on.
EDIT 23.03.2020:
Look at this video guys. Focus hunting is gone. Sorry, I have orange blinds and the sun was shining directly on those.

Specific to the S20 Ultra, what about subjects' edge blurriness issue due to narrow Plane of Focus? - it can only minimally get resolved or may not at all..?
For reference, attaching pics taken from YT:
MKBHD(at 9:31) and Danny Winget(at 1:41). Marques explained it pretty well on why it might not!
Edit: S20 Ultra users with the OTA updates( "ATBR" & "ATC2") installed can check and report..
so in Germany i got a Day1 update but it seems to be only the March security patch. the update was a Little less than 500mb.
the autofocus is kinda slow in compare to the s10+
and the autofocus has some Trouble tu Focus with zoom 5+ and distance lower than 5 meters
update:
in the patchnotes
- better cam perf.
- enhanced security 4 the device
Version G99BXXU1ATBM
431.19 MB
so hopefully there will be another update to improve the cam

I think that this update fixed the problems with the main camera when capturing photos with a recognizable face. I have tested it yesterday and it does not change the colour of my face or make it smoother.

I have already read some feedback from gsmarena who stated: According to TizenHelp, users are reporting improved function of both autofocus and manual focusing on the Galaxy S20 Ultra.
- It is nice to hear that but we need to wait for some comparisons or a wider update push. I have also watched how Marques explained the narrow point of focus on the Ultra and he might be right but that hardware masterpiece has other sensors to help the main one with information so maybe it can be fixed with software update. I have already asked German Samsung support about when the update is going to roll out because the camera is almost useless and that I am very disappointed about it. Of course I also wrote that if it does not happen before the return window closes, they will get that hardware back, simple.
EDIT: They just answered that they do not know when the update is going to roll out. They also did not respond to me being disappointed so I asked for Tier 2 Support or Customer Relations response.
EDIT2: This was already a Tier 2 answer and they do not know on their own when it is going to arrive because it is being rolled out without properly informing all Samsung Sites.

Autofocus/manual focusing improved, but I think let's not mix it up with the Plane of Focus limitation i.e. after the object is in focus, clicked, the pic is sharp on few places but blurry elsewhere on the same object.
As for Samsung support(customer support?) about Samsung, I will rather ask my Pets about it..

I know that support from such big companies is mostly not helpful but if they throw a voucher for something, then there is at least something useful you get if they cannot help. As I have written before, the other lenses could help with the Plane of Focus. Maybe Samsung will figure it out. Samsung integrated Google Duo so let Google guys improve the camera software :silly:
They're not going to be able to fix the narrow focus depth of close up images. Have you ever noticed that "fast" zoom lenses with constant aperture for cameras are invariably heavy and expensive? That's because they cram in several aspherical lens in there to be able to maintain the wide aperture. But on a camera lens, you can adjust the aperture if you want to increase the focus plane. The Ultra has a variable zoom with fixed aperture, so it's a trade off. They may be able to improve the focus hunting issues but I doubt it will ever match the speed and precision of the dpaf of their cheaper siblings.
For this reason I changed my pre-order at the last minute to the s20 plus. My subjects are typically closer range shots that are moving (my kids), so auto focus performance is important.
