How does the Note III know you have a finger hovering over the screen, and where it is hovering over the screen? So we are being told the entire screen has a built-in proximity sensor and how does that work? I am waiting for the Galaxy Note 3 and an currently using an S3. The S3 has a proximity sensor but that I believe is only a tiny hole up at the top of the front of the phone - not the whole freaking screen!?!?!?!?
Very confused, must be magic or made by the Gods.... ??? LOL
Anyone can shed any help on this?
I think it does have some sort of prozimity built in the screen.See S pen...you can select without even touching the screen.
A digitizer is a device that creates a small electromagnetic field and then measures disturbances in that field. Thus knowing when your finger touches (disturbs) the screen (and electromagnetic field)
In the Note 2 there is a second digitizer that detects the different way the S Pen nib interacts with a magnetic field at a distance, and thus is able to show where the S Pen is hovering.
In the Note 3 they use similar technology but is now able to detect your finger at a distance instead of just the S Pen nib.
I think I got all that correct, if not... someone will correct me
And, if I am wrong
Must be magic or made by the Gods
Magic to impress your iPhone friends.
I miss this so much, it's like optical "mouse" together with main button on HTC Desire, one of the best features in decades. Seems that last time we could hover over screen was Note 3 and S5. Sad.

Hi,
there is something I have been really wondering about lately, and that is wether the HD's touch screen is multi touch capable by hardware, e.g. the hardware is able to identify several touches at the same time.
Now, if you do the following test, start Notes, and press two fingers at the same time on the screen (writing a note with touch). You will notice that the line is drawn in the middle between your fingers. I then started to think that if the screen isn't mulitouch capable by hardware, the point/line would either choose one finger and stick to that, or jump between those two fingers, not draw a point perfectly in between of those two. As it looks now, it seems that the point that is sent with the mouse click event, is a calculated point based on your fingers(1). A calculation that might have been done in the touch driver.
Now there might also exist another reasonable explanation to this, and that is when you press several fingers you press down a larger area of the screen at the same time(2). The point is then calculated to the center of this area. However, this does not realy fit in with the technical design of a resistive touch screen.
I have tried to explain in figures, look at the attachements.
Now, if scenario 1 should be the case, then there might be a chance to reverse engieneer the touch driver and create a multi touch capable phone right?
If anyone have more understanding on this field, please correct me. Maybe I can get some sleep after all.
Sorry for any typos, it's early in the morning..

I have a QVGA Titan and have noticed the same thing.
Also, say on TF3D hold down your finger on the home tab and then put another finger on the tab on the other side of the screen while still holding the home tab and it will go to the tab between them. Also if you slowly release one of the fingers it will cycle through the tabs....

is the screen heat or pressure sensitive, and how is the multitouch?
Neither. And so far I can't complain about the screen one bit. I do find myself simply tapping the screen to auto-size the browser, been easier than using two hands.
Its heat although the proper name is Capacitive meaning is only works with fingertips or a specialized " iphone " stylus, which i have and dont work very well tbh although mine was a cheapy off ebay (like 60cent for 2)
i just tried one at the store and noticed that it was not as sensitive as the iphone's. if my finger was on the hero light enough there was no response, but no matter how light i try to go on the iphone it always responds.
It is not heat.
Wiki:
"A capacitive touchscreen panel consists of an insulator such as glasshttp://en.wikipedia.org/wiki/Glass, coated with a transparent conductor such as indium tin oxidehttp://en.wikipedia.org/wiki/Indium_tin_oxide (ITO). As the human body is also a conductor, touching the surface of the screen results in a distortion of the local electrostatic field, measurable as a change in capacitance."
And who cares if it's not as sensitive as the iphone? When would you ever try to press a button as lightly as possible in real life? I find it better that you actually need to touch the screen for a button press, leads to fewer mistakes with random light button brushing. I have yet to find a time when the screen doesn't respond when I want it to.
Feels just as sensitive to me. I very lightly ran my finger over the screen and it responded just as well.
As a left-hander, the S-Pen SUCKS.
I've set the phone to left-handed, but that isn't the issue.
The phone expects the user to hold the pen at an angle away from the user, and that's where the screen registers.
However, many left handers hold their pens at an angle TOWARDS themselves, and the S-Pen is off by nearly HALF A CM!!

Tell me about it...
It's so irritating
are you sure you got it in left hand mode? i have mine set to my left hand and tried writing with my right. was off like you said (to the right). tried again with my left hand and it seemed fine.

I have it set to left handed.
When changing the settings to right-handed and using my right hand (I'm a little ambidextrous) it works fine. Nice and accurate. Mostly because with my right hand I hold the pen at a conventional angle.
However, many lefties don't hold their pens conventionally (habits picked up by the necessity of avoiding ring bindings, minimising smudging, etc). Look at how President Obama holds his pen:
http://www.post-gazette.com/pg/images/200901/20090126ho_lefthandedobama_330.jpg
See how the nib of the pen is angled TOWARDS him? The Note thinks it's angled away and puts down a line in totally the wrong place.
Even with my slightly less unconventional left-handed pen hold, it's WAY out (no matter whether the unit is set to left or right hand use, though left is slightly less awful).
How hard can it be for Samsung to provide a calibration app?
Right now, the Note is a phone unsuitable for a President!
Do you find any difference when you change the screen orientation then back again?

None at all, unfortunately.
I find that no matter what I do with the pen it always seems to write half a cm above where I have contact on the screen

SPen uses autocalibration feature, which unfortunately goes off after some time. Which is a bug by itself but not the point..
Everyone complaining about pen being way off try this:
set it to whatever your hand preference. Please phone on flat surface like a table and reboot phone. Do not shake or touch it too much. Open SNote and try to draw around grid lines, you will see that pen works perfectly with tip being exactly as expected.
However more you use pen more it will deviate off until reboot is needed. It happens especially fast if you are using it walking, upside down etc.

Interesting (though it didn't help in my case)
But it the calibration goes off after time, then there is even more reason to add a calibration facility.
I reckon that only happens when you're using landscape orientation and then you turn off autorotation without first returning to portrait orientation. Try turning autorotation on, setting it to portrait and then turn it off. That should fix it.

Thanks, but it really is nothing to do with orientation in my case.
It's ALL about the angle at which you hold the S-pen.
It expects the nib to be angled away from you, whereas I hold a pen with the nib angled towards me.
Hi everyone,
I wonder if I'm going crazy, but you're supposed to be able to turn off S Pen detection when the S Pen is holstered. However, on the lockscreen this doesn't seem to be properly implemented. What I did was to holster the S Pen with that option turned on supposedly to reduce power consumption, then take my Note 10.1's S Pen and hover it over the lockscreen. I could then clearly see the watercolour effects as if a finger or S Pen were being dragged across the surface. However, the device will not unlock. I have to say though, that my device is a lemon - the screen has blue specks and streaks on dark areas so I'm waiting for Samsung's response to my case. I don't know if these two issues are related, but... is that option to turn off the S Pen detection actually working properly? Could someone else with another wacom stylus please try this and see if the device continues to detect the S Pen at the lockscreen even with that option on?
Cheers
I am happy, apart from WiFi problem, Note 3 user but I have some questions regarding spen. I havent head any experience with spen before but I guess my expectations were higher then the reality, so here we go:
1. Shell the spen be sensitivity be equally good to my fingertip? In my case, finger servse it purpose better.
2. When I use the spen at an angle ( so colled natualr writing angle) the reception is poor. is it normal?
3. Shell I apply slight pressure when using the spen, or shell "the touch" itself be enaugh?
4. The worst part is about the capacitve buttons, I need to tap with the spen, 2-3 times before the device registers it.
Please help me out, as I need to make my mind before I go complaining
Thanks!
I went to the shop and tried the note 3 before I bought it. (3 different shops).
At the shop I played around with it, mainly with the s-pen.
I can definitely say from my own experience (30 min all up) that I found using the pen quite easy, and while I I needed to get used to it for the first couple of minutes, I experienced no issues.
I also used the pen from another samsung tablet that was next to it and found no problem.
I will say that my finger is much less accurate than the s-pen.
If you have a problem, try and go to a shop and try their note 3 pen on your device to see if its different.
You could try a tablet pen as well to see if that makes a difference for you.
Good luck.

The S-Pen is Wacom pen technology based device, which allows presure sensitive writing/drawing if the program/App makes use of this.
You will see a pointer if you come close to the screen with the wacom pen and moving across the screen, in windows tablet the mouse pointer is already there but will move with the pen movement too.
You have to touch the scrren with the pen tip an provide at least minimal preassure. The benfits are:
- if the programs do not support preasure sensitive input you may assume that it's not better then your finger.
- If the program supports preasure sensitive writing/drawing the line will get thicker or more pronounced e.g. if you draw using the spray paint. -
- Other Wacom pens work too, e.g. the S-Pen from my Samsung Slate7 win7 X700T1a tablet. It's slightly larger and better suited for work.
- The main benefit over the smaller pen that come with the Note is that on the opposite site of the pens tip is the erase button, that allows you to erase parts you don't won't.
- In addition to the keayboard you get also handwriting recognition, which is toggled by a button on the keyoard.
Unfortunately Samsung does not provide many details on the interfaces or versions, but I would assume it to be around 256 presure steps. Wacom tablets may be as high as 1024 -2048 steps.
I hope that helps you to have a better understanding of Wacom technology and what to look for. For me the Wacom based pen was a large reason why I choose a Notes.
Thank you for your answers but I am rather then understanding the technology trying to identyfi if the s-pen that came with my note 3 works as yours.
I just wanna ask if it register / works the same as yours and if you are experiencing the same when using it.
1. Is is as respoosive as your finger when touching the screen? Is just "touching" just enuagh, or sligh pressure need to by applied when navigatin between screen or while browsing?
2. And the captivate buttons, do they register your taps every time?
Thanks!

1. A slight touch on it. Just like how you touch or tap it using your finger.
2. Yes, since Note 8.0, S Pen works with the captive buttons. Ours one too.
Different between using S Pen and finger for the Air View is:
1. Finger - you can preview picture / SMS / header / email / speed dial etc
2. S Pen - besides what the finger could detect, S Pen also act as the mouse hovering mode and you can hover it above most of the icon and shows you a description what does the icon do
