[Q] i9505 camera focus ability - Galaxy S 4 Q&A, Help & Troubleshooting

I had my i9505 with me for 3 weeks, it is very well in my experience with fast and longer battery life compare with MY GNex
However, I tried to take photo outdoor at night or in restaurant sometimes, the camera focus ability seems not as good as my GNex.
It always out focus or even cannot focus ( the focus square in RED ), I tried to tap on different point on the screen to get it focus but it still not focus even the point I tapped has big contrast of color.
Does any one have the same problem or my camera is a fault unit?

I too upgraded from the Galaxy Nexus and do not experience any of these issues. My camera focuses quickly and overall works very well compared to the galaxy nexus.

(Q) Does your Nexus have shutter lag? (Camera)

Just wondering if anyone else has quite a bit of shutter lag on their nexus camera? I personally do unfortunately, is this normal? Many people say theirs is instant .

The N4 doesn't have a zero shutter lag for me either.
HDR setting will slow things down but will make the pictures nicer. Try toggling that and see if it helps.

lag variation between N4s
Just bumping this topic. I recently started using burst mode on the CM10.1 camera, and noticed the shutter on my wife's camera is able to take twice as many pictures as mine in the same amount of time. She and I have nearly identical Nexus 4's.... both running CM10.1. I was using a custom kernel (Franco), so I reverted to the stock CM kernel, but the lag persisted. I'm hoping that it's some sort of software configuration issue... but it's starting to look like there is simply some variation in the Nexus 4's that have been manufactured. Can anyone else comment on the shutter speeds of their respective N4s? What ROM/Kernel combos are you all using?
I don't have this problem but sometimes when I use the camera right from the lock screen.. exit camera, go to gallery, exit come back to gallery after some time have pass, all my pictures are blank. I can't view them until i FC the gallery.. Occasionally when I go to the camera app, instead of the lock screen too.. Only bug, I know with my first nexus 4 and my replacement..

It's of course going to vary on how well it can focus and what kind of focus mode you have.
With point and shoot cameras, the general advice in the past (back when they were a bit slower than they are now), was to eliminate as many automation possible (ie: if possible manually set iso, white balance, etc). Can also set the focusing mode to something else rather than continuous.
I'm not a huge fan of the camera's lag, but the quality is higher than past camera phones I've had, but because the sensor element is probably larger, it's probably more likely to delay as it gets better focus (Smaller sensor will have wider depth of field so won't need to take as much time to focus, but the clarity isn't as good either).
I kind of wish you could set stuff like shutter speed, f-stop and such on the N4's camera, but it doesn't really surprise me that I can't (besides just how many aperture stops could it possibly have in such a lens before diffraction hits it).

camera FPS i guess every one should read

hello everyone ..
now i have been using my s4 for 6 months and i actually enjoyed them ..
but when it comes to the camera the quality is awesome but the shutter speed is why i am disappointed
in this video
i guess a lot of you have seen it
when it takes the photo it's like the phone stopped the time there is no that blur (the slowness in the shutter capturing)
every time i try to capture a moving object i get a blur in the photo
so any one of you have a solution for this ?
and i really can't understand why SGS4 Can't Record 1080p60FPS i guess the hardware is really capable of doing it
i hope to see your opinions .
I can tell the worse of this model is first the camera and second the battery for me.
Talking about the camera: the hardware is possible maybe, but the software still not either. Im listening all days how the members of my job speak about Samsung Galaxy s3, Note, Note 2 reminding the camera was so much better having less megapixels and less options for the photos or videos (one simple AUTO and u had a perfect photo/video everytime). Im very dissapointed with the camera of this model and with the new Note 3 camera too.

S4 shutter really slow?

I noticed this phone has very horrible low-light performance (super blurry photos) with or without anti-shake enabled (I keep it off now). Night mode does help a LOT but I am wondering if anyone knows why this camera is so bad? Not trolling when I compare it to the iPhone 4, 5, HTC One X, and HTC One to the S4 that the former are so much better... Maybe Samsung phones just do not have the hardware to produce decent photos?
I do have minor shake in my hand but it was never an issue with any of the other phones I mentioned.
Anyone else experience the same issue (and yes, I have removed the plastic surrounding the lens)?
It's the 13 MP, and the phones tiny sensor. Not trolling but that little sensor has to do a lot of work. Also, the HTC one has a larger sensor

I shoot mainly in sports mode. Took this today of my never motionless daughter. In low light I just use my Sony NEX3N. The S4 struggles in lower light because of the slow shutter algorithm. Nexus 5 was much better at focusing but much noisier as the devise just ramped to a high iso. So it's a trade off. Samsung went for the lower noise option which increases shutter time.

Yeah I am no camera guru, it is a given the HTC One would perform better in low-light compared to the S4, cannot say I am surprised, I was just shocked at how bad performance really was. I don't have much chance to shoot during the day since well, I am working. We'll see how my summer shots come out, for now I guess I will keep it in night mode during the evenings.
Night mode just boosts iso and runs a noise reduction algorithm. You are better off shooting in sports
The other thing that lowers shutter speed is enabling stabilization mode.
Sent from my SGH-I337M using XDA Premium 4 mobile app
Thank you, I'll change it and see how photos turn out. Is there a way to default the shooting mode upon opening the camera app? It seems to default back to auto all the time.
I'm running MDOB rom and it saves the camera settings
Sent from my SGH-I337M using XDA Premium 4 mobile app
Yeah, night mode or sports mode I have concluded this camera is horrible compared to even previous generation cameras... I should have known better when the Samsung Galaxy Nexus had a horrible camera that not much would change...

Does the camera blur moving shots indoors?

The note 3 and s4 blur shots if your subject moves in low light conditions. Have they actually fixed this in the s5 or is it just the same.
Right now my note 3 bugs me as any pictures I take of my son indoors blur, if he moves in the slightest.
I've had 2 note 3s and an s4 they all had this issue.
It's weird how all the camera reviews never cover this.
Any info would be much appreciated
Having received my S5, I can say the differences between the S4 and S5 camera aren't as pronounced as I would have hoped. There is a difference in the quality of the final shot in favour of the S5, but the process of taking the photos, in terms of shot speed and auto focus speed, isn't that different, especially in low light conditions. Actually, with the new low light 'hold still' shot mode of the S5, it's slower, although the final result is much better.
I'm actually debating returning my S5 and returning to my old S4 contract which only had 12 months to run.
So far my M8 wipes the floor with my S5 on those shots - indoor, medium light. It still blurs, in other words. Tomorrow I'll be able to test more. I've enabled face detection, maybe that'll help. I shouldn't have to hold the camera still for 4 seconds every time it has to get a decent shot in medium light...
I really really wanted to love the S5, but so far the only improvement in the camera over the S4 is the speed. And honestly, I'd argue the quality might be worse in some scenarios b/c of this new isocell technology.
Disappointed by low light performances. My Z1 is way better. Pictures taken in broad day light are excellent though.

Camera Blurry

Hey all, received my Note 4 today and the camera quality isnt great, the pictures look blurry even when keeping the camera perfect still. I have taken the plastic film of the lens. Just wondering if anyone else is having this problem
Can you upload an example? Does this happen in low light, outdoors or both?
They were all taken indoors, some with light from room light and sun light through window and others just with a room light (on ceiling). Obviously one with a flash (flash was on auto for all of them but was only used on one after changing iso and white balance). They all just seem a bit grainy and blurry... or is it just me, ill try get some outside tomorrow
Indoor shots will look worse because the ISO will be higher and there's more chance of blurriness with a slow shutter.
Also make sure that you take a photo soon after a focus lock. When I'm indoors,I tend to use touch to shoot and touch on the part of the image I want the camera to focus on.
Sent from my SM-N910U
indoor the camera sucks. the only mini fix i have found is to take iso off auto and put it on 100 for indoor shots.
Ill use the touch to take pic and try the iso at 100, i dont understand cameras lol
Also i read somewhere to put the metering mode on matrix, its comes on centre weighted so should i leave it on that?
The Note 4 camera isn't very good. For perfectly still shots it's not so bad but any movement at all and the pictures turn into a blur fest. There is something wrong with the software on the phone, there is lag in places there should not be. The note 3 out performs the 4 by a large margin. I think this lag is the reason the camera cannot handle movement. I have tested several Note 4's. Some from TMO and some from Verizon (mine is Verizon) and it affects all the ones I tested except for the demo model I tried at Target. For some reason that one blurred much less and was much quicker when snapping pictures.
I use my camera a lot, this will probably be a deal breaker for me. I was hoping to see a good rom that would fix the lag issues and hopefully the camera problems with it.
Couldnt it be fixed in a firmware update? I have also noticed it to be a bit sluggish in places.
Theres also a hair inside the camera, underneath the glass but luckily its not over the lens,theres a hair inside the heart rate sensor bit as well. So dont know if that will affect anything

That right there would be the ultimate deal breaker for me. Any hair, human or otherwise, in my phone is an automatic return or warranty repair. I can handle some non-uniformity of the screen and stuff like that, but hair? Ick.
I've noticed that the indoor camera sucks pretty bad. Everything's a bit yellowish. Images can be adjusted a bit with the included software, but still not great. Outdoor photos are not so bad. But considering how hyped the camera was on this phone, it's a major letdown.
I think the camera is great considering it's a phone and not a digital camera (people seem to forget that sometimes) Almost all Android camera's perform bad in low light because of shuttertime limitations in de Android camera API (it simply does not provide long opening times) . Not much any Android smartphone manufacturer can do about that. Also if you're using flash indoors it's a LED not Xenon flash. Even the cheapest digital camera is using a real flash and outperforms a LED flash device.
regards
Seems it will get much better possibilities in Android L

All true. They just need to stop hyping these cameras as digital camera replacements and all that. It sets unrealistic expectations.

This camera is worse than what it should be. I hate to see apologists come in and make light of something that is obviously very wrong with the note 4.

And your information is based on what? It's no apologize that Android camera API is limited, it's a fact. What you don't understand about that? In other words you can put a professional CCD chip in a Android phone and it can only profit to certain amount of it because of OS limitations to access the hardware. Lucky the Google developers have seen the light and in Android L there will be improvement.
Hell no! Ur camera is ok! Its just ur eyes

I have very realistic expectations of what the camera should/can do and it doesn't do it. Also the in general lag is not right for the processor this thing has.
Like I said the note 3 has it over the 4 performance wise.
I'm hoping it's just simple software fix and things will be in an acceptable state.

That's your expectation, I can't argue with that. I do know for sure there is no Android Smartphone on the market, which camera performs better then a cheap 60 bucks digital camera . Which is logical because of OS limitations I mentioned.

The lag (if there is any) is mainly caused by TW AFAIK . I can tell you from first hand that the Note 3 does not perform better then the Note 4 as they are laying both in front of me now in my desk. Also you have take in account, that the Note 3 is longer on the market and most bugs (if any) are tackled with software updates, while the Note 4 is just 4 weeks on sale.

You're disappointed in your new phone because of your own expectations, if you can't live with it ,trade it in against? Honestly I wouldn't know which phone to choose then myself.
Thanks for this thread. Its convinced me to stick with my note 3 after all. I've been waiting for an honest discussion on medium/low light shots indoors with the note 4.
Funny how no review sites pick up on this issue. Hopefully lollipop will make my note 3 take better shots anyway.
To me there is no good reason now to get a Note 4, especially with lag reports.
A n6 is maybe still a consideration having dual speakers, which is now the only significant upgrade to me. That or pass on upgrading this year.
IMO the lag on the note 4 is no worse than that on any other android phone I've had (I'm on the third plus three different tablet models) and I don't think it's all that bad.
Drop by your local store and give it a try for yourself though from what I've read, there's no compelling reason to upgrade from a note 3.

Some reports did compare..... and note 4 outperforms note 3 buy a huge margin.
1. Not all cameras have ois, not even the note 3. Note 4 has it and that allows for relatively long shutter speeds like 1/8s (I've seen note 4 do 1/4 once but that's rare). That's a huge upgrade from note 3.
2 . The note 4 uses sony's IMX 240 sensor which is 1/2.6 inch size. The note 3? And older generation sensor is of a smaller 1/3.06 size. Now. Note 3 is 13MP and note 4 is 16MP. So individual pixel size of both cameras is of the same 1.12 um size. However it's a known quantity that IMX 240 's has better iso performance than I'm 135. Thus note 4 should have better low light shots.
3.its been known that the note 3 takes bad low light shots due lack of ois and the old IMX135 sensor.
4. Almost all galaxy series engage in some kind of "image stacking" software to reduce noise in low light shots. Aka night mode. This is probably low light shots EXIF data is eroded .
As for the lag. What lag ? Jerkiness in viewfinder? Lag in auto focus?
From phonearena
" Outdoors at night, the Galaxy Note 4 soaks in quite a bit more light than the Galaxy Note 3, which results in more visible illuminated details at the expense of overexposure. Photos taken by the Galaxy Note 3 look decidedly darker and noisier in comparison. They are also much softer, while the Galaxy Note 4 retains fairly sharp detail. Low-light photography has seen a big improvement in the new phablet, and by dialling down the exposure setting a notch, you will emerge with more usable night photos than before. "
From Engadget
"But low-light performance is what impressed me the most about the Note 4. While ISOCELL helped improve the GS5 over the Note 3, it still wasn't very good. Optical image stabilization has made a tremendous difference here; objects that barely show up at all on other Samsung cameras can be easily seen on the Note 4. In fairness, the images still don't look as natural here as they do on the iPhone 6 Plus, but this is by far the best nighttime imaging performance I've seen on a Samsung phone."
If your note 3 does better low light shots than note 4. Your phone is probably faulty or you picked the wrong settings for the camera.
It's funny how so many people here expect unrealistic results from this camera. Is this camera better than a PnS camera? Nope.
This this camera worse? Not really.
If you're talking about junk market for PNS cameras. They use a 1/2.3 inch sensor which is not all much bigger than note 4.
A lot of them don't have OIS or Sony's newer image sensors ( Sony's sensors are widely used in many brands).Note 4's image quality is probably better
If you're talking about the mid segment. They use approx a 1/1.7 inch sensor which can probably do a little better low light shots. But they are not really cheap anymore. Eg canon s120. Olympus xz2 etc...
Note 4 loses out a bit here. But that's cause these cameras are meant to be an upgrade from smartphone cameras
If you're talking about about the premium segment. Eg canon gx7 gx1 Sony rx100. Most of them have 1 inch sensors which boast relative great low light performance.
(They still suck compared to mirrorless or dslrs though). However they are probably as expensive as your note 4 or even more.
