Focus hunting - Galaxy S III General

Is it me or is there too much focus hunting when recording video. It happens even when there is no change in object distance or holding the phone still.

If there is no change you can tap the display to set focus that will last, but i agree it doesn't have best auto focus

Hi there, a suggestion : ALWAYS tap the centre of the screen to have fixed focus, in any situation. You will have very good videos without focus hunting......

Macro Problem

I don't know why, but when I try to take macro pictures a certain distance, I hold the camera button halfway so the focus is made, I then see the picture getting real clear and suddenly a pop from clear to blurry, and it tells me the focus is done, anyone else experienced this? I mean, at a bigger distance I'm able to take the picture correctly, but if I'm a little close this happens, and since during the focus I do see the picture crystal clear for half a sec it should work I guess..?
God I miss my XSi...
I ve got the same... its irritating and its all because of ****ty camera software... i tried with vingette and focus works as it should...

It's soooo annoying :/
Would've been nice if there was a manual focus mode.

[Q] Camera focus problem

So, just curious if anyone knows if there's away to fix this or not. But I'm have problems with the camera and it focusing on close up objects. The only reason I bring this up is because when the camera app "tries" to focus, the subject in question will come into focus, clear as a bell, and then go right back out of focus and it'll take the picture. And yes, I've got spot focus on, and tap and hold the screen where the subject is. still nothing.
i'm hoping this isn't one of those hardware to software hindsight's where there's no way to force the camera to focus where you want it.

Not sure tap and hold screen part. You have your finger on the screen when taking the pic? Maybe I just misunderstood you. But you normally tape the screen where you want to focus and then it should focus automatically and then just snap your picture.

Nah, you do have to tap and hold in order for it to take the photo, thats normal. My camera focuses though and takes the picture no problem.
yeah, you can either click the little shutter button or tap and hold a spot on the screen and it'll focus there and snap the picture.
guess i should have been more clear. its having a problem doing macro focusing. if the subject is a food foot or more away, it focus every time, perfectly.
the problem is when i'm trying to take a photo of something very close to the camera. And the only reason I'm asking about this is because when it "tries" to focus, the image will indeed come into perfect clarity, and then go right back out. and sometimes several times as if the focusing is trying to find the right spot. and ultimately it just gives up and everything is blurry. And I'm left going what the...? because obviously it can focus on it, but why wont it?
My temporarily solution for now is to zoom in that tiny bit allowed and use that to get as close to the subject as i can before the auto focus stops working and get the picture that way. still not really what i want, but it'll work.
Set the camera to AUTOFOCUS, open the keyboard and use the ENTER key as the camera button.
Additional tips.
Turn OFF shutter sound and timestamp to speed up the photo taking process.
Leave ISO and Whitebalance to auto as they seem to work pretty well on the shift.
Quality HIGH
Geotag off (unless you REALLY need this)
NO review speeds up time to next shot.
Center area metering mode seems to work surprisingly well on the shift, especially with flash set to auto.
Also, note, the CLOSER you are to an object you are photographing, the more still you NEED to be. Panaramic/outside shots with a large DOF are awesome. Closeups at 6", you seriously gotta lay off the coffee and brace yourself well. 1mm of hand movement will blur your photos really bad. That's a intake of breath or exhale!
This isn't exactly a professional high speed Nikon with prime lens we're working with. Set your expectations accordingly.

Ok, I take back what I said about it working for me because I have the same exact problem with it looking focused and then going out if focus.

I'm seeing the same problem. It focuses very clearly just before snapping the shot, but then the picture it takes is out of focus. I've tried the tips here and nothing improved on the problem.
Cameras need light to focus. It's going in and out of focus because it doesn't have enough light to tell where the object is in relation to the background. Plus you can only macro so close with a camera lens. Try getting more light in your shots and see if it helps focus. I ran into this yesterday and fixed it by moving the object to a better-lit location.

I know this thread is old, but I think this is a big problem. Even if the subject is well lit, and you use spot metering or tap on an object just a few feet away to focus, the lens will focus and you will see the object become really detailed, then the focus decides to focus on something behind it, rendering the object blurry. This is the case with almost every photo that I take of any object within 3 feet.
Lets say I take a photo of a flower outside in the daylight. Any foliage behind the flower will be focused on, even if you press directly on the middle of the flower.
My theory is that it seems to focus better in lower light situations, where your subject is the only thing lit. If the entire frame of view is well lit, it will make the majority of the image sharp.

Smart Rotate

Wondering if this is working for everyone? On my ALIE firmware the feature doesnt seem to function as described, i.e., my eyes/face rotating 45 degrees does not cause the screen to rotate at all.
keep the phone on a flat surface and rotate ur head it should work
press thanks if this helped

i wish it was that simple. Just doesnt work.
What are you trying to do?
Smart rotate is just for 90 degrees. Imho, it is for people lying down.
Sent from my GT-N7100 using XDA Premium HD app
Smart rotate doesn't check if your head rotated or not at random times, it only checks your heads/eyes position when the phone is rotated 90° (in other words, whenever the phone is supposed to rotate, it does an extra check before doing so)

Doesn't these face detection gimmicks like smart rotate and smart stay use gobs of battery power since the front camera is active e?

could be that your face is too ugly or disfigured for the feature to recognize it. sorry

It only checks every now and then.
In fact, I bet it only checks when the phone is rotated.
Regardless, the amount of power used by a quick camera check is minimal compared to the power needed to light the screen.

Can confirm on mine, that this is to stop the screen rotating when you yourself rotate with the phone, for example when lying down.
It would seem it only checks when the screen attempts to rotate (you see an eye icon in the notification bar briefly). I do believe that this actually causes a slight delay when you do want to rotate the screen as it will need to do the check first.
i believe it needs to have a good clean shot of your face in portrait mode first, then it can detect your 2 eyes turning to landscape and thus do a rotate.
I need this feature when in bed at night (for reading mostly) but it doesnt work in the dark so its totally useless for me.
Samsung should have put in a small low power Infrared LED (which is a light source cameras can see but humans only see a dim red light) - this would have made the feature work in all situations or at least work in most situations.

Check the phone in complete darkness .. there is a very feint red light emitted from the sensor area!
Mine would rotate normally whether I enabled or disabled the option. When I rotate the phone, the eye icon would appear on the notification bar. It takes about 1 to 3 seconds, and then it rotate no matter where I'm pointing the front camera to. It would even rotate in the dark.

Yeah, I've noticed that too.
Is it some kind of IR-light?
This feature is a hit and a miss.. really annoying when watching an youtube video.. even before enabling this feature samsung warned about lag or slow screen rotation... probably they might be working on this feature and might release an update fix soon...

[Q] Camera keeps focusing?

The camera focusses over and over again, is that the way it should be? It auto focuses very often when I try to take a picture.

I have the exact thing happening with me. I think it may be the camera in this phone. My RMA did it also (before I sent it back, because it had more issues than the original). Doesn't focus this often on my old Samsung Infuse running 4.2.1.
Connor Baker
Mine does it too, not sure why. I've found that once you hold the button to focus, then slide your finger off, it stops focusing. Then tapping the button should take the picture. While it's a crap method, it works for me instead of trying to time the focus correctly. Alternatively, simply tapping the button should focus it once and take the picture, though it may not be great in some cases.
So it seems to be normal I guess!
It's a feature, though not working very well. The idea is to have it constantly focused so you have zero shutter lag when you press the shutter key.

Poor focus in live focus mode - Can someone please see if you can replicate?

S10+ UK variant with the latest updates installed. I have an issue with the camera. If I open the camera and choose Live Focus, the default lens is the one with the single leaf on it, which is the lens that makes everything the biggest/closest etc. If I hold my hand or anything else out in front of me, the camera will not focus on my hand/object at all. If I wave it about, it will sometimes come into focus momentarily, but will not focus as you would expect, the image is also quite poor. If I then change lenses to the other available one, which is the one with two leaves on, that focuses perfectly and very quickly and is nice and sharp in the areas that I choose.
Samsung said to factory reset and I did and it did not fix it. They also said that Tracking AF setting should be enabled, but it is greyed out and there is no way to change it. I found a video on youtube on how to enable it, by reducing the resolution of video recording for the rear camera, but as I'd just factory reset, it was already on a low setting.
Also, all 3 lenses will focus as they should in auto and pro modes, just not live focus.
Could anyone please try this for me?
Open camera->Select Live Focus->Select the lens with the single leaf icon->Hold hand or other object about 12 inches/30cm away. Does it focus properly?
Also, with the camera still open->settings->Tracking AF <--is this greyed out?
Thanks, any help, much appreciated.
Same with me. Never noticed before as usually nor use live focus mode.

For me the 2x zoom camera(single leaf) has problems of focusing when I shoot a video. Try that also and see if you guys have the same problem

Thanks. Yes, mine is the same. I had mine set to 1920 @60fps and there's no option to change lenses, but after setting it to just FHD 1920x1080, the 3 lenses are available. The focus here, although not working as expected is better than it is using live focus.

I am using 4k 30fps, and for me sometimes the focus for the telephoto(x2) struggles to get perfect. Maybe is a software thing that will be corrected. Also checked it and the tracking AF is also greyed out for me.
