I have found threads and info about how it works on the Note 2, about magnets in the stylus but how does it know when your finger is hovering over the S4 screen?
Anyone know?
I have the same question.

The one at the top of the phone?
So it sort of senses downwards as well as infront of itself?

No.
It's the same old touchscreen controller technology just much more sensitive.

What are stock apps that able to utilize this function. I only notice this when I use Flipboard.

I read somewhere that it was indeed the sensor at the top, mixed with the old technology too.
The apps I know it works with are stock email, stock texts and flipboard. Not sure what else. It doesn't even seem to work on lockscreen...

How to use the air view on Stock text? I thought it can show the contents of text from text overview display. But when I tried, nothing shown.

Samsung is using a super sensitive capacitative touchscreen that can sense your finger even when its a short distance from the screen, essentially. its the same reason that there's an option so that you can use it with gloves on
Sent from my Nexus 7 using Tapatalk 4 Beta
I'm no engineer, but this is my basic understanding gleaned from reading wikipedia and other sources. Capacitive touchscreens work by sensing changes in an electrostatic field. Your finger is an electrical conductor, which distorts the field. In normal phones the field is calibrated to extend just past the surface of the touchscreen. The S4's electrostatic field is simply overcalibrated to sense your finger from a distance, and it's also why it works with gloves on.

nothing to do with the capacitive screen or proximity sensor. if the screen was THAT sensitive it'll be firing off to even the slightest atmospheric disturbance. actual workings are related to the 2 IR sensors flanking the speaker grill which individually log IR intensities emitted by ur finger in front of the screen. an algorithm then compares these values and works out where ur finger is pointing.
AFAIK it works with help of IR Sensor and/with Proximity Sensor
If screen sensitivity does this job then ...Nokia Lumia 920 to 520 all devices all should have this feature cuz all these devices have Super Sensitive screens

The air is much more inert than your finger. The proximity/IR sensors just blast IR beams away from the phone for things like Air Gestures and have nothing to do with Air View. They certainly don't shoot beams across the surface of the screen to detect your finger. The finger hovering simply uses a more sensitive capacitive touchscreen, as Sony explains here:

This happened with me also.
The air view works in stock messaging app , gallery , flipboard and even when you dial a number if you have speed dial feeded.
For this you need to hold air view option in notification bar for about 2 seconds then a set of options will open. There you can switch on air view for messaging, gallery etc etc.

It will be the electromagnetic field that the screen is detecting from your skin/finger. The same way that on other screens, they don't work with gloves unless you have the special gloves that have conductive fingertips on them.
Nothing to do with the sensors on the top of the phone cos if you cover them up, air view still works! Plus the sensors aim out the top and at 90 degrees to the phone face, how would they sense something almost touching the screen on the bottom?

I saw a cover for the nexus 7 that said it turns the screen off and on with the closing and opening of the screen. I assume it's done with the light sensor. Is there any way to dk it with the gt?
Sent from my GT-P3113 using XDA Premium HD app
those use the proximity sensor, and we don't have one so unfortunately no there is no way to set that up.
Its not the proximity sensor, its some sort of magnetic sensor. It does it if you have a small magnet in the right place on the case. As we do not have such a sensor on the tab, we cannot do the same thing.
In theory, you could write an app that turns off screen depending on what the light sensor senses

maybe on your 3100 but I installed this app https://play.google.com/store/apps/...51bGwsMSwxLDMsImNvbS5vbWQuYXV0b3NjcmVlbm9uIl0. that uses the proximity sensor to wake the screen and it said there wasn't one on my 3113. All I have is the camera and a light sensor.

ok, cool, auto screen on was just the first I had found and it worked on the device I tested it on so I never looked for any others. still no use on my 3113, it says no proximity sensor.

This works, however if you are using screen timeout, its not saving you much since it just turns the screen off, it does not put the device to sleep. It does function as an auto on / off for the screen. I found it very quirky , sometimes it works when I close the cover, sometimes it does not. Unfortunately there is no sensor calibration. I want to test it to see if it actually uses extra battery in order to keep the sensor alive. Also, its a bit flaky if you use some of the advanced features like turning on and off airplane mode.
Thanks. I didn't know about the magnet.

No need to write such an app. There are several on the play store that do exactly that.
However I've tried them all and I can' get any to work properly using CM10. Others may have better luck.
Use smartcover from android market. It works very well.
Hi guys, I just got a brand new S4 from Rogers and while playing around with the phone I noticed some of the features weren't working properly. One of them was the palm gestures settings. I tried some many times to get the Screen shot and Play/Pause features to work but it failed. And another problem that I encountered was the gyroscope sensor. As you can see in the screenshot, the ball doesn't move at all even when the phone is standing up. So do I have a defective S4?

That screen is supposed to "calibrate" the gyroscope so it make sense that it doesn't move. You are essentially teaching it where perfectly centered is. In order to do that, you have to lay it on a surface that is perfectly centered. If you lay it on a surface that is not perfectly centered and press it, it will be off. I haven't messed with mine yet, but it seems that is the way it would be.

Yes, I see it... I have no idea what it could be. It's not listed on the Consultant Guide or the Manual (http://downloadcenter.samsung.com/c...UM_EU_Jellybean_Eng_Rev.1.0_130910_Screen.pdf )
It is no doubt a sensor, though which remains a mystery.
Temp and humidity sensor. Is the only one.who needs contact with the surrounding air. On the bottom the heat from the process will alter the readings. I'm 100% that i'm right about this.

Common sense. I do.have S4 with temp.and.humidity sensor and it's a hole more than the two mics. The Note 3 the same, only other placement of the hole. the S4 active does not have the temp and humidity sensor...so no extra hole, just thw two mics.

Isn't humidity and barometer sensor supposed to help with location in google maps? And I would suspect that those might be useful in a crowd sourcing app or whatever for more accurate weather per location if it is available to be used that way which as of now I don't think it is.
This article is an interesting read about how the sensor got incorporated into samsung devices/android.
Acording to Anandtech it's actually the third microphone that's used for noise cancellation : http://www.anandtech.com/show/7376/samsung-galaxy-note-3-review

Hi, I've my unit purchased in India. Don't know which model. I think It's 9000. It has a hole in the right side. Don't know what for. Besides, on the bottom right, next to S Pen slot, there is a rectangular open slot too. Any idea?
Using the S-Pen, when you hover it at the top or bottom of a list/page, it scrolls.
There are some hover functionality for fingers as well, such as showing gallery previews for different folders.
I'd love to be able to hover my finger at the bottom and scroll

Probably not possible. The hover function that is used in the gallery app uses the sensor above the screen. The S Pen uses some other kind of technology. I dunno much, but basically when you have the S Pen close enough to the screen, the pen becomes active due to electro magnetism from the screen which it picks up and it gets power to do for example hovering & scrolling.
I might be terribly wrong, but this is somewhat how it works. I think.

Yesterday my air gesture work normally, but today it wont work.
I dont know what happen.
I check sensor on *#0*# and air gesture sensor is not responding. but when try quick glance on air gesture setting, its working (just quick glance try).
Do you know how to fix this?
Maybe something to do with your digitizer. The digitizer produces a tiny magnetic field which collects data when distorted, this is how it tracks your finger and the spen.

My air view is fine.
Can detect my finger and spen without problem.
I thought air gesture using sensor beside proximity.
Correct me if im wrong.
