[Galaxy S 4 Q&A, Help & Troubleshooting] TheFeshy:
Taking 8MP pixels does not fix it; and would not necessarily fix it even if the poster you quoted was right. He is (mostly), but it doesn't apply - he's talking about a slow shutter speed whereas this thread (despite the misleading title) is discussing a shutter lag. They are different phenomena. Even if we were talking about a slow shutter speed, reducing the image size would not affect the shutter speed because you're still not changing the fundamental properties of the camera - the ratio of lens size to sensor size nor the light/noise sensitivity of the sensor's pixels. Reducing image size does not simply use a smaller part of the sensor; that would be "digital zoom."

Things I've found that make the lag worse:

Macro shots have a large lag

Low-contrast in the focus area is a huge lag (but that's normal for any autofocus)

Dark colors seem to take a little longer than light colors; but maybe this is just in my head?

Can someone who hasn't taken the update, or who has flashed back, check the shutter lag on the camera and see if it really was better before the update?
[Galaxy S 4 Q&A, Help & Troubleshooting] BarryH_GEG:
Both LG and Sony phones have 13MP cameras and there haven't been reports of this issue so it's most likely not related to megapixels.
[Galaxy S 4 Q&A, Help & Troubleshooting] TheFeshy:
My post agreed with that ;) Although those phones have almost certainly have differences in sensors, lenses, apertures, and image signal processors, so that would hardly be conclusive. However, the S4's "drama shot" mode works fine, and it requires something like 20 shots in two seconds - so clearly taking pictures quickly isn't a problem. The problem is some initialization and focusing before the picture is taken, and as earlier reviewers didn't note it it's likely a software problem introduced with the update.

Yeah, not possible to mute the camera sound. Very annoying indeed! I know there are some legal restrictions on muting the camera but again, s3 wasnt like that. You could easily mute s3 camera sound.
[Galaxy S 4 Q&A, Help & Troubleshooting] malikons:
Thanks for the feedback. I have changed the thread title. I am no camera guru and don't understand the technicalities. All i know is that the camera is not as fast as S3 and the result is blurry even in day light.
[Galaxy S 4 Q&A, Help & Troubleshooting] TheFeshy:
Blurry pictures could be shutter speed, or it could be shutter lag - as you generally move the camera after taking the picture. I'm experiencing shutter lag, and that's what I saw others talking about - but except for some poor lighting and moving subjects I haven't had any blurry pictures. If you are, you might want to check the exif data of the pictures and see what the actual shutter speed is. Compare it to your S3 too, since it's giving you different behavior. I'm getting about 1/20th of a second under normal indoor lighting conditions (daytime) which is usually fast enough but sometimes blurs my squirmy children and pets if they move quickly. Outside I'm seeing 1/500th of a second under relatively clear days, which shouldn't result in any blur. If the shutter speed is reasonable, then try holding the phone steady for a few seconds after the picture.

I'm able to turn off the shutter sound (stock MDL update on T-Mobile's S4 version.) I just went into camera, hit the gear icon, the gear icon that pops up then, and then the gear icon tab that pops up. It's second from bottom of the list. It's possible that the availability of this feature varies by region or carrier.

+1. The camera app really is a downgrade from S3. Who loves paying premium for downgrades ? Anyone ? (All eyes on you Samsung)
[Galaxy S 4 Q&A, Help & Troubleshooting] Khy50:
You have to put the phone on mute to have no camera sound. Very annoying I know.
[Galaxy S 4 Q&A, Help & Troubleshooting] dagnammit:
Has anyone tried it with out the anti shake feature. I know I get a message saying hold the camera steady or something. I'm so hoping it's a software issue. Maybe, just maybe it could be another feature that's conflicting with something else??

Does anyone know if this is happening with CM 10.1 roms as well?

If it's not, we can be sure it's a software issue.

I thought I was the only one finding that the photos I was taking were coming out blurry.
[Galaxy S 4 Q&A, Help & Troubleshooting] plasmastate:
For those with blurry picture complaints. Tap and hold the camera button until it focuses just right. Then release for quick capture.
[Galaxy S 4 Q&A, Help & Troubleshooting] gregpot2000:
I am aware of doing this, and have done with every camera I have owned and had no problem apart from this one

Still got my Sony Ericsson Satio, and that still is by far the best camera phone I have ever used, why don't manufacturers use proper xenon flashes anymore!?
[Galaxy S 4 Q&A, Help & Troubleshooting] marci4na:
it takes the picture: it's true.

are you sure the lag is less?
[Galaxy S 4 Q&A, Help & Troubleshooting] wallslide:
I was also getting consistently blurry photos, and the problem turned out to be that you cannot have "Auto night detection" and "Anti-Shake" on at the same time. I naively turned on "Auto night detection" thinking that of course if it can change to night-mode automatically I'd want that. Unfortunately, that automatically turned Anti-Shake off, and I had the problem of blurry pictures even in good lighting. For now, I have turned "Auto night detection" off, because it's not worth having blurry pictures all the time. When you turn it off, make sure to turn "Anti-Shake" back on.
[Galaxy S 4 Q&A, Help & Troubleshooting] marci4na:
thanks!

what about metering?

anyone knows how change things?

wich is better??
[Galaxy S 4 Q&A, Help & Troubleshooting] Mithrandir007:
I'm guessing they use LED instead of Xenon flash because Xenon cannot be used as a flashlight, or for filming with the flash on.
[Galaxy S 4 Q&A, Help & Troubleshooting] gregpot2000:
I'm sure my satio has an led light as well!
[Galaxy S 4 Q&A, Help & Troubleshooting] aami.aami:
its actually the method which the camera uses to determine the exposure and how to work with that.

this is more important in DSLRs and other dedicated cameras. but in mobile phones it works just a little. (but it works :D )

i will try to put it as simple as possible for u here :

spot metering

: it should be used when u are trying to capture something thats well lit and has somewhat dark background (eg. capturing an image of moon)

centre weighted:

in this metering system, for exposure settings, the camera will take into account about 60-80% of the viewfinder. this is mostly used cause it takes most of the sensor area and this is the reason its used as default metering mode.(eg. day to day shots)

matrix mode:

here the camera determines the light intensity in various parts of the scene and then selects the best one. (eg. infinity photography where the light intensity varies a lot)

hope i helped :D

I just grabbed my gf phone which is my ex phone i9305... do u guys think the s3 camera was instant ? No it wasnt I just compared them both and its the same thing when u press shutter its not the exact instant that u touch the screen, there is a slight delay in both s3 n s4 I think u may be expecting too much of it. Dont forget your taking higher resolution shots aswell compare to the s3... but after comparing in the same time I was able to take tbe same amount of photos and I actually found burst shot to be a touch quicker on the s4
[Galaxy S 4 Q&A, Help & Troubleshooting] Khy50:
To be honest, the camera lag is not even that bad.. You just need to keep the phone (hands) steady, before and after the shot.

Taken some shots today which came out crisp and clear. Just needs some getting used to, but of course Samsung can further improve this.
[Galaxy S 4 Q&A, Help & Troubleshooting] plasmastate:
If you guys owned an s3 before you will also notice that the flashlight intensity is also alot less than of s3. I can't understand why.

---------- Post added at 05:23 PM ---------- Previous post was at 05:17 PM ----------

Yes I cqn confirm. Once the camera focuses properly. My pictures are taken instantly just like s3 . within the same focal range. But when the focus needs adjusting then it takes time. For example from far focus to macro and vice versa.
[Galaxy S 4 Q&A, Help & Troubleshooting] Rashawn30:
If you guys try pro capture its has a mode once you hit the shutter button it focus before taking the picture.

[Galaxy S 4 Q&A, Help & Troubleshooting] jj03:
Haven't noticed any real lag myself yet..tho my handset is less than a day old...i just hold down the button, release, and its done.
[Galaxy S 4 Q&A, Help & Troubleshooting] exec99:
You just hold down the button and then release you say? On a s3 you just quickly tap the shutter button and it's done. No need to hold and wait.
[Galaxy S 4 Q&A, Help & Troubleshooting] noideaforusername:
I think he meant you tap it and then it's done. This is how it works in mine (even with anti-shake turns on).

just noticed that the Front camera having no lag as well as S3. I believe it should be software issue on my 9505... hope it will be fixed soon...
[Galaxy S 4 Q&A, Help & Troubleshooting] Beefheart:
I had my friends S3 today and spent ten minutes taking photos side by side with my S4. I tried various settings with both cameras, but ensured they matched as much as possible given the difference between the two camera apps. But most of the time I had everything set to auto. It has to be said, the difference in speed is palpable. Both buttons pressed at exactly the same time and the S3 had taken the photo and almost had it displayed in the gallery application before the S4 finally took the shot. Overall I'd say it was around twice as fast.

Very, very disappointing and, larger image or not, Samsung should be ashamed of themselves that their newer model can't compete in this respect. Didn't anyone bother to check?

Here's hoping firmware updates to the camera make a difference to the speed but I doubt it.

[Galaxy S 4 Q&A, Help & Troubleshooting] mr.r9:
I have the same issue. Every time the camera lags I keep checking if I am using HDR or Night mod, but I am not.

This is the price that we pay as early adopters my dear XDA'ers. Add this to the list (Random reboots, extremely hot device during minor tasks, incomplete kernel support for big.little...etc).

As much as I'd like to blame Samsung, I cannot because they did not force me to buy and become an early adopter.

So people, I suggest to suck it up and wait for a couple of software updates.
[Galaxy S 4 Q&A, Help & Troubleshooting] jonlad1:
Also have the shutter lag. Have tested against wifes GS3 and definitely at least 50% slower

I have also tried some shots in bright sunlight and checked the EXIF data - 1/141 shutter speed....in bright sunlight????

Wait, that's your response? Seriously, why bother?

Facts:-

1) in terms of shutter speed there is a considerable difference between this phone and Samsung's last generation 2) it's not unreasonable to point this out on a forum such as this and 3) doing so isn't'crying.

Appologies to those users and mods for my inappropriate remarks to a certain gentleman.

Regarding shutter speed...i am using the sd600, and am on a pre-rooted mdm stock rom..my experience is that the delay is very slight...and to me personally, just not an issue. I do remember my s2 having to be held for maybe 2 seconds longer after taking shots..so maybe i am use to it.

[Galaxy S 4 Q&A, Help & Troubleshooting] Soupturkey:
I noticed this when I was taking pictures the other day. There is a slight pause, close to 1 second. I tried it with another Camera app and found it had the same pause. Don't know if Samsung can fix it but hoping they can.
[Galaxy S 4 Q&A, Help & Troubleshooting] NZgeek:
I'm running the PACman ROM, which uses CM as a base. There is a slight lag between hitting the shutter and a picture being taken, but this is almost completely focus lag. If I focus first, there's about a 0.1 second delay in taking the shot. This is about on par with what I'd expect for a compact camera.

I don't know if there was any difference from stock because the first thing I did with the phone was to root and blow away TouchWiz.

Well it looks like it's firmware related then.

The newer firmware of the i9500 seems to reduce the shutter delay as well, though it might be placebo (I just tried to take a few pictures before I installed the custom ROM with the newer firmware, the day I bought it) :)

Hi I have a problem with my s4 camera.

It seems that the right side of the picture is blurry.

When I focus on the centrer,the right side is blur.

Then when I focus on the right side the right side is ok and the center is blur.

You should say it's normal but the the subject of the picture has the same depth of field!

Here is an example

Focus on the center:

Focus on the right:

When I take the picture using panorama mode the problem disappears!The issue increases when the subject of the pictures become far.

No problems with near or macro shots.

Is it hardware related?

does yours s4 do the same?

thank you
[Galaxy S 4 Q&A, Help & Troubleshooting] jonlad1:
I have used the default stock (AU), pre rooted XXUBMEA and now on Omega v5 on my i9505 and they all have approx 1 sec shutter lag. I had the camera firmware update too. I have tested the shutter directly with my wifes (used to be mine) S3 and the difference is night and day. The S3 is near instant between pressing the shutter button and the taking of the shot, whether is has to focus or not. I normally pre focus by touching the screen where I want to focus.

I really hope that Samsung can reduce this shutter lag. Coming from the S3, its really noticeable.

(hopefully they're reading this :cyclops:)

I'm really happy with everything else though :)

FYI - Omega v5 rocks :)

Camera failures

Finally i found a topic about the poor camera on the S4 but this post is completely about something else then i experience... Maybe you guys have the same but just not posted it here yet. My problem:

Btw: Fact is that i am comparing the camera with the S2 i had before.

First of all when i make pictures outside i have absolutely no complains at all. The quality is great! But when it starts to get a little darker or when i am inside i think the camera is far below average...

When i try to take a picture with poor light i just have to take like 5 pictures to make sure 1 is ok, but they usually are all blurry and moved and i end up with no picture at all. No matter what mode i chose, normally i chose auto, but when the light is poor they always fail... I tried different things and different settings but it's just impossible to take a normal picture.

With the S2 on the other hand i never had any problems like this. The pictures where always good and very often one was a blurry or moved, but on the S4 i just can't take a normal low or medium light picture other then holding my hands very steady for a couple of secs, but with a moving object it's just impossible.

Anyone else experiencing this problems? I already found some people on a dutch forum with the same issue, but in every review i read i see nothing other then good reviews and great picture quality, but i just disagree with this (on low and medium light situations)...

Yes. Agree totally. Inside pictures have a ridiculous amount of noise and grain!!!!!! Really awful.

Outside pictures are amazing!!! The HTC one is a better overall camera phone but outside pics are just ok.

I had both and prefer HTC one camera overall as it's more versatile but low mp count and a couple of you're camera issues bugged me too much. Lucky I take most pics and vids outside as s4 is best camera phone I have ever used (outdoor) really sucks inside with artificial light. Must be some kind of processing Sammy are doing with indoor shots?
