Auto Focus before snapping picture? - T-Mobile Samsung Galaxy S 4

Just got this Galaxy, amazing phone and whatnot, and installed wicked rom.
Tried all three camera's (GE, stock, moto) and none seem to auto focus right before a snapshot. It only auto focuses while the camera is active not right before taking it its own and this causes me to take blurry pictures (I have horrible steady hands). Basically it focuses only before I click the snap button I want it to do it automatically after I click it.
My old E4GT however does it and it is one thing I loved about it. It would take a second to capture the picture but it would take it in perfect focus because it would automatically detect it right before the shot after I click the snap button.
Any ideas on how I can add that feature to this phone?

Mine auto focus after I hit the "snap" button. I'm on Infamous S4 V4 ROM so I can't speak for Wicked. It shouldn't be any different IMO. Maybe play around with the settings.

I just hold on to the snap button for about a second and that focuses it really good, and that takes really good quality picture.

The camera on the s4 is not as quick to take sharp pictures as my note 2 other s3. I've just learned to tap the screen to focus first before taking a pic. Or I just tap n hold on the screen for a few seconds and once I let go it takes a pic automatically

I'll try that ROM because this is really irritating how my S2 takes better pictures than my S4.
And even stock rom auto focus before you hit the snap not after which is really weird.

I tried that, it's really good suggestion but I just can't seem to do it. I don't exactly have surgeon hands, in fact I have the exact opposite.

I believe I've noticed that if you hold the camera directed towards the focus of your shot for say, 5 to 7 seconds, although delayed, it will adjust by auto-focusing SLIGHTLY. Not as good as just tap on the area of the screen that you want focused.

He is saying he wants it to re-focus AFTER the shutter button is pressed before it actually captures the photo. So the process would go like this:
1. Camera opens
2. Point at subject
3. Auto focus on subject to frame the shot
4. Press shutter button
5. Re-focus
6. Capture image
Plenty of cameras out there do this, and as pointed out, ours do it when the flash is on. They will vary the amount of light from the flash and lens focus simultaneously to capture the best picture quality.
I don't see why it doesn't do this either, my old HTC did the re-focus after the shutter button thing and you get much more clear photos. I sometimes have to try a couple times doing close up shots of things like text on identification tags (so I don't have to write numbers down) with my phone myself, and I have "normal" steadiness hands.

Okay, you want it to focus once, then after its already focused, focus again? Really? Thats kind of defeating the point. You already have focus on the subject why would you need focus on it again? That makes taking pictures much longer a process. However, if it doesn't have focus already, and you press the shutter button, then it takes focus again. But i have no issues taking crystal clear pics unless i accidentally move while its snapping the pic. But the way it focuses now is normal and how it should be. Focusing twice is really pointless..

The OP was asking, not me, and he said he has shaky hands which is why he misses this feature. It only takes a fraction of a second for the camera to do anyway. A lot of phone cameras do this already and you don't notice it. Heck, most hand held digital cameras focus before capturing the image AFTER you press the shutter button.

Lol i wasn't trying to point fingers or anything lol. I am just extremely confused, if my phone doesn't have focus and i press the shutter button, it focuses then takes the pic. but if it does auto focus before i press the shutter button, and i move then immediately press the shutter button, it will refocus.. so i am extremely confused as to what the OP wants..

isn't this marketed as a "feature" called zero shutter lag? I use procapture the majority of the time and it focuses after clicking the shutter.

[Q] Camera doesn't focus well

Ok, I'm having a hit or miss problem with the camera. I have fresh 3.1, btw.
I'll try to take a picture of something, for example, I have a rubix cube here. keeping the camera about 8" away from the cube, trying to get a picture of the word "Rubix". I tap the button to take a picture. the camera goes in and out of focus, it focuses the word "Rubix" perfectly, then goes out of focus and snaps the picture. I've tried tapping the screen to focus on the specific area, and it still does it. I've tried holding the button down until the picture takes, but it still goes in and out of focus, then snaps a blurry pic, or at least the area I want focused is blurry. Another issue with the flash... When the flash goes off, the camera will focus in and out on the object, and usually hold until the flashed area is focused and not washed out. But the camera just snaps the picture without focusing.
Like I said, both problems come and go. Any ideas?
I've searched and I still don't see any answers. Anyone?
The camera on the phone is pretty bad IMO. Typical results.

Indeed Jason, indeed.
The TTF utility is very hit and miss. As is the entire camera functionality.

The camera focusing algorithm appears to be flawed.
It will take someone to completely rewrite the camera app code to make this right with the evo camera.
It's clear to me that the AOSP camera code doesn't work well with the Evo camera. And unfortunately, HTC chose not to use a new code, but rather use the default Froyo code with this new piece of hardware.
Until someone takes the time to write the proper code for focusing the Evo camera, you are stuck with trying to manually focus the camera, multiple times, until the good looking focus is achieved.
It takes me good 5-10 times to manually focus the camera until a good sharp image is seen...

Camera Button to Volumebar

Is there any possebility? It drives me crazy when you try to take a picture of a friend and yourself!
I searched a whole lot, but this "Big Button Camera" App that is out there replaces the normal camera and its not free.
If there would be an App that lays the Shutter on volume Down or Up during camera mode, that would be great! I can zoom (if I need it) on screen...
what did HTC think?
Self-portrait

For making pictures of yourself you can use the self-portrait function. The phone then sees your face in the frame and takes a picture. Works quite good.

Yep ... it's awesome.
Face recognition doesn't always work for me.
Another alternative is to set a delay on the photo. Gives you time to position the camera before the picture is taken. Not sure why HTC have only given two options - 2 secs and 10 secs - though...

Open the camera app by clicking om the app or long pressing the camera button. Then just tap on the screen or press the camera button to take the pic.

Or use the panorama app for X10 for that.

for the panorama app you have to move the phone from left you right.. at the right speed..
For normal photo's you either press the camera hardware button.. or switch "touch" on so that you can just touch the screen where you want it to focus and take the shot.
Suspect though.. that this might suit you better.. HERE..

Xperia S Camera Focus Problem

It keeps on focus and unfocus for near objects.
I dont think this is the product's defect but it comes with the release.
How u guys solve it or minimize the problem?
Should I go to Sony centre and claim? Cause there will be enough proof and they probably cant answer about it.
You're trying to focus on object closer than the minimum focus length.
Sent from my LT26i using xda app-developers app
That's called continuous focus and is active when you are on one focus point - if you change to multiple focus points - there will be no continuous focusing, it's your choice.
Hi, I think Pixy132 is right there - sounds like you're trying to focus on something closer than the camera can handle.
tbh the stock camera app is awful. I downloaded Camera FV-5 (paid app but cheap) recently and wouldn't go back to the stock one for all the tea in China.
The dev is good with communication too and I've already helped him iron a couple of bugs out with it ( I have NO affiliation )
The other good camera apps are UCam, lgcamera and Camera MX. All have a decent Macro focus mode that lets you get stuff like the one I've attached (cropped a little but not much!)
hth!
Try using touch focus
It makes the camera focus faster

What about problems like slow focussing?
Once i press the camera button, It adjusts the focus and take the photo. But sometimes it can't focus properly before the photo was taken.
It happens with all of you right?

Press the focus button first. When its focused, you can take a picture.
You can also use multi focus or touch focus.

There's another issue regarding your suggestion.
When the camera button is gently press (focus), it sometimes lock the focus too early that the image is still blur.

Forget the stock camera app - it's terrible (I'm a photographer and trying to grab snaps with the Xperia was driving me mad).
Any of the ones I listed in the previous post focus quicker and more accurately by far compared to the stock app. Image quality is better too. Seriously, change the app and start enjoying using it!
btw the pic I uploaded seems to have been "softened" by this site. It's much sharper than that!

LG Camera takes ages to save the photo and sometimes losses it

I've noticed if you snap a photo with LG Camera app and immediately press the back button or switch off the screen, the photograph is not going to be saved and you will loose it. You really need to wait until you see a preview of it in a circle on the right side.
And that time can be up to 2-3 seconds, which is really annoying.
Native google camera doesn't have this bug.
Has anyone else experienced such behavior?

No problem here...... Just tried it.
If I snap and immediately press the back button it quits the camera app but if I go back into the app the thumbnail of the shot is there.
So no, my G3 takes the shot and saves immediately.

That's why it takes a while.. HDRs don't render instantly and need some time to process. The reason it doesn't save when you back out is because it's still taking pictures.

So, I understand that, but why does it need to discard the photo if I close it too fast ? Can't it just schedule the processing in the background like Google camera does ?
With Google camera if it is in HDR mode and I switch off the screen immediately after taking a picture, the photo will still be saved.

I believe it's because the way HDR works is it takes multiple pictures at different exposures and puts them together so maybe the lg camera takes the pictures more slowly and you're quitting it while the shutter is still open?

As I said before, a google camera app doesn't have this problem. It produces hdr fine, even if you close the app immediately.
Obviously you gonna ask why am I not using it. I find that lg camera produces better results in HDR mode.
I usually don't reply to semi trolly post but I just took an HDR and instantly hit the back button and it doesn't save. (Of course) but I did the same thing and waited MAYBE a second maybe less and the photo finished processing and saved even though I backed out.
@op does the phone close when you take a picture or are you just intentionally hiring the back button that quickly on purpose? I literally had to try to NOT take a picture to keep it from processing. In just curious why someone would back out of taking a picture each time so fast. Well an HDR anyway

I presume that LG camera made that behaviour intended, programmers decided that if back or home buttons pressed immediately after pic is shot then use decided not to save picture so camera stops processing completely and doesn't save photo on memory. I think it is not problem it is a feature.

1. I do not talk nonsense especially when photography is the subject.
2. My previous phone was a Z2 which I would hardly call inferior.
3. If you wish to take a non standard photo then you also have to allow the processor time to complete it's action. As such 3 seconds (which by the way it is nothing like this on my G3) is adequate.
4. What gives you the right to insult any user. All that was given to you was an example of a waiting period prior to doing something else. In no way did that give you the right to be offensive.
