i've seen a function in s4 where you can swipe pictures back and forth without even touching the screen
is this hardware related or software related?? cause i'm thinking of getting note 2 cause of its size and the pen and s4 specs are not really worth an upgrade from note 2, and i would really like to have the floating swipe thing.
hardware related it's called Air gesture and uses a sensor
Sounds like software related to me

This is not hardware related, this is pure software feature. The front camera detects hand gestures and responds accordingly

Wrong, it is hardware related. There's a sensor up top of the phone that recognizes air gestures and allows interaction. Think about it, how else could it be?
Smart scroll ( when you tilt the phone and the front camera sees your eyes and scroll up and down) and smart pause ( when you watch a video and you look away and it pauses) is also hardware related, well front facing camera related. The S3 will be capable of smart scroll and smart pause when Samsung release it but won't be capable of the air gestures because it lacks the sensor to recognize the hand movement.
On the note phones, it works with the Wacom digitizer and the S-pen interaction.

Probably not completely true here. I have used an app on my SGS3 that does control some things with just hovering the hand over the screen called Wave Control. It is basically only used for pausing,playing music etc. but it shows that even the sensors in the SGS3 can do things by hovering/swiping over the sensors.

Now I am NOT saying the SGS3 will work as good as the SGS4 but I saying it does already work on the SGS3 to some as sense of the word. So WHEN the SGS3 gets the software and or firmware for those sensors updated to the same android version as the SGS4 we MAY have the same functionality built in. I am sure the sensors in the SGS4 will do it better? but until we actually have the phone in our hands we will not know for sure and until they are running the same software. So it is ALL speculation at this point. Plus I think I remember at the unboxing event they mentioned it as well working on the SGS3.

Does the app that you downloaded work for every android phone or just galaxy phones? And I'm pretty sure the S4' s sensor is the one that makes the air gestures possible. Otherwise what is its function?

Not sure what other devices it works on. I just know that it works for music. Plus looking at the pic you posted up IF the two sensors on it that are used for the gesture it may be that the SGS3 uses the same sensors as the sgs3 has those two (or looks the same at least as far as location of them). I would have to look up what sensors the SGS3 shows in a pic to know for sure. There is a FREE version to try out. I did the paid version. I haven't used it much but I saw the potential and wanted to help out the dev. He is here in xda.
Some of the things it can do.

S4 has a sensor for that,meaning hardware related .

Everything stock
There's a dedicated "Gestures sensor", so it's a hardware thing. You might achieve similar effects with the front camera or proximity sensor on other phones, but I doubt they'll be as good.
If you mean the two dots on the right side next to front cam,Its an IR proximity sensor.Even the very old SGS has it and almost all mid range phones too.May be samsung made it a better IR proximity sensor by doing some changes to make it adapt to gestures.But on the base line,It is again just a IR proximity sensor.

The galaxy S 4 has one extra sensor up top that the S3 doesn't have. It's the gesture sensor.

No...look closely and you can see 2 dots on almost from s to NoteII.
The one on the left of ear piece in s4 is Light Sensor...So all s4 has extra sensor on top is Light sensor.

Yes, but check on both sides of the ear piece, there are 2 sensors on the right of the s4's earpiece and one on its left side. the others only have the two on the right side

Yeah...That is what I clearly stated one pair of sensors on right is proximity which all devices have and the new one on the left is Light Sensor which only s4 has.

I would like to see the same kind of pic for the SGS3 to clarify the ACTUAL sensors for comparison
But the TWO on the right look the same as on the SGS4 and then has the addition of the other one on the left. So until I see an actual breakdown of the sensors on the SGS3 I am just plain confused.
Are the two sensors on the SGS3 Right side of earpiece a proximity sensor and light sensor? Or is it a proximity sensor and what is now called gesture sensor? If that is the case where is the light sensor on the SGS3? I looked around a bit but didn't find the same kind of sensor location breakdown for the SGS3. I JUST KNOW hovering works/swiping works on the SGS3 and I think I remember the Samsung event actually making a comment it would work on the SGS3 as well.

It's cool. Ok but according to the Samsung sensors pic, the gesture sensor is on the right and the proximity one is on the left.
edit: my bad, the proximity is also on the right.
Looks like the SGS3 has the light sensor (rgb) and proximity sensor. So this would mean on the SGS4 they moved around the sensor locations and added the gesture sensor.

True lol. I was just about to write some kind of explanation but it didn't sound like I was going to make sense. I'll search it and share it
Hello, I was wondering if anyone knew what the sensors on the fron of the galaxy s4 are. It obviously has a camera, and one is a proximity sensor. I think one is a light sensor, but whats the 4th?
Anyone know? Is it something for motion tracking? (and if so is there an api for it?)
(On an unrelated note, is there any api for the hover above the touchscreen?)
Thanks. I'm just curious. It seems like these phones have more sensors that there are things to sense lol. (seriously does a phone need a pressure sensor and barometer? )

Sensor for air gestures.
Here. Pretty cool picture with lots of info about the sensors on the GS4. As always, GOOGLE SEARCH FIRST!!

Oh so it does have a dedicated one. People on the internets seemed to think the gestures were combinations of the camera and proximity sensor.
But is there anymore info about it? I would love to know more details. And any api?

I edited/updated my post... check it out!
Try taking the photo with the phone positioned on top of something, thus it will be steady. Have just tried taking a picture of some text 3 times and each was slightly blurred, took photo with phone on table and was spot on.
Shame that these phones don't have OIS
I must be having a shakey hand day!
Anti-motion blur scn mode help here at all ?
Finger prints or something on the lens, bad focus selection eg no good contrast variation for the camera to make a valid decision, or you have an issue hardware
Maybe your Z1 has some hardware issue. I always shoot handheld and no blur unless you are shooting in low light.

You can try to use the micro distance photography pattern.
If you phone still can't automatically focus, it may be the camera has broken.

I believe it's some kind of pattern that you can print out in order to test/adjust your lens's focus
Gathered as much with a quick google, thing is cameras must have a facility to make this adjustment.
The Z1 or any phone for that matter does not have it.
Hi,
I like to take videos and picture of laser show effects, I have done that for years without any problem.
However I got my brand new LG G2 took one 2 minutes video and ended up with about 30 scattered group of dead pixels on the CCD sensor... never happened with my galaxy S2 or galaxy S3. I was about 10meters from the laser projector, it was not very powerful (only 500mw RGB projector with 30kpps galvos, wide beam (~1cm diameter at 10meters)), there was a lot of fog, there was no direct still laser beam on the ccd, only fast moving patterns, the laser could have been on the ccd no more than a few milliseconds.
Maybe higher megapixel sensors are more sensitive? this is quite worrying, I know many discos that have much stronger lasers than that and I see people take pictures/movies all the time. Also, would direct sunlight burn the sensor as well?
Anyway, I got it exchanged under warranty no question asked...
David.
I don't talk about own experience, but from what I understand will every camera sensor be damaged when directly exposed to laser, or long exposure of the sun. Whether it is a expensive dslr, compact camera or mobile phone.
My guess is that the sensor was briefly directly exposed to one or more lasers in your case.

are you using an aftermarket camera? all aftermarket video recording shows dead pixels for some reason. the stock LG camera app doesn't. it makes no sense, but everybody is able to recreate the issue for the most part.

Since our G3 has the laser focus shouldn't it be able to see at night?. Night vision uses IR light which the laser focus puts out. Now all we need is an app to process the IR light from our laser focus an boom we have REAL night visiovision not like those fake android apps. The best part about it is only our G3 are capable of doing it.. Take that Apple and Samsung.
Afaik to use IR the camera sensor itself would need to be able to capture the light emited in the IR spectrum. This is pure speculation right here since I havent read on how the laser autofocus works, however I do believe it it only used to measure the distance to automatically adjust focus tpfor that distance. Emiting IR and capting/reading the IR is 2 different things.
Also, I can clearly see the laser autofocus as a red dot (not very smart, but SCIENCE). So the I'm not quite sure that the autofocus module can even detect IR.
And add to that, we're surrounded by IR. Emitting and being able to capture ad process the infrared spectrum around us with a sensor that was made for the visible spectrum (400-800nm) would be impossible to do unless it can also detect longer wavelengths (IR).
Tl; dr: Can't be done. Laser is red light, not IR. No infrared receiver/sensor. Camera sensor can't detect IR.
PS: Sorry if this is a bit hard to understand. I'm used to explaining physics in french lol

1) Laser autofocus if a point source. It's ray is very focused and weak. Besides, it's in visible spectrum (though quite close to IR).
2) Our camera has an inbuilt IR filter. Until it's removed, it won't see in IR.

Re point 2):
I don't believe that is true.
I use the g3 camera to verify that my IR emitters are working. The IR emitters operate outside of the visible spectrum and I can't see them. Point the g3 camera at them and boom they're visible. Test it now with your TV's remote control.
I cannot speak to point 1). However, I believe the threads OP is right, the tech is in place and all that is needed is:
a) someone capable of writing an app to exploit it; and maybe possibly,
b) an IR emitter LED array (perhaps built into a case or a clip-on attachment) to address point 1). To that point, the camera flash is an LED (light emitting diode) and therefore, by changing the input voltage can emit light of any colour in the visible spectrum; and I submit - should also be able to emit light in the IR spectrum.
