Nope. No battery.
Of mild interest...I have a Samsung Slate (Win 7) which also has a Wacom stylus. (Stylus works on Note too.).... the Slate stylus came with additional , replaceable tips. Seems to suggest that the tip will wear down.
Its not a stuiped question,,, actually this is my first device with a pen,,,,im wondering why if hold down the button on the pen and press the screen you can capture a picture,,,,but touching the screen without holding down the button does nothing,,,what is that button actually doing?..how does the device recognized the difference?...

I shamelessly stole this from Wikipedia:
Wacom tablets use a patented electromagnetic resonance technology. Since the tablet provides power to the pen through resonant coupling, no battery or cord is required for the pointing device. As a result, there are no batteries inside the pen, which makes them slimmer.
Under the tablet's surface (or AMOLED display in our case) is a printed circuit board with a grid of multiple send/receive coils and a magnetic reflector attached behind the grid array. In send mode, the tablet generates a close-coupled electromagnetic field (also known as a B-field) at a frequency of 531 kHz. This close-coupled field stimulates oscillation in the pen's coil/capacitor (LC) circuit when brought into range of the B-field. Any excess resonant electromagnetic energy is reflected back to the tablet. In receive mode, the energy of the resonant circuit’s oscillations in the pen is detected by the tablet's grid. This information is analyzed by the computer to determine the pen's position, by interpolation and Fourier analysis of the signal intensity. In addition, the pen communicates other vital information, such as pen tip pressure, side-switch status, tip vs. eraser orientation, and the ID number of the tool (to differentiate between different pens. mice, etc.). For example, applying more or less pressure to the tip of the pen changes the value of the pen's timing circuit capacitor. This signal change can be communicated in an analog or digital method. An analog implementation would modulate the phase angle of the resonant frequency, and a digital method is communicated to a modulator which distributes the information digitally to the tablet. The tablet forwards this and other relevant tool information in packets, up to 200 times per second, to the computer.
Wow. And people say it's just a stylus. I never knew Wacom pens were complicated. Thanks!

What is the best stylus for the capacitive screen we have? I am looking for something with a fine point, let me know your opinions, thanks in advance!
Not how capacitive screens work
That's not how capacitive screens work. No matter how fine a stylus is, the screen will recognize the same thing. This is because a capacitive screen does not measure based on pressure, it measures based on current (At least, that's what I've been told).
If you wanted a finer tip to do finer things with,I'd go for an active digitizer display or resistive screen based phone (Which are basically obsolete now due to active digitizers and capacitive displays.
Hope that helps a bit.

Yes it is true that capacitive detects current instead of touch, that does not mean that it is less accurate when discussing location of touch. The underlying grid determines this, but in todays screens, I would think it is as accurate as a resistive screen.

thank you but i am not looking to exchange this phone for a resistive phone, so given this new information, what is the most accurate stylus that isn't too thick
I was looking for the exact same thing, and ended up going with the "Newest Generation Slim Capacitive Stylus" by A Young Life (AYL). Got it off Amazon, but it might be available elsewhere as well. Works great, slides with minor resistance, and has a much narrower tip than other pens I've used.
While point width doesn't make much of a technical difference, it certainly affects usability. All capacitive stylus models I've seen use a round tip, and the point of contact at the bottom of that little semispherical nub is what registers as a touch on the screen. No matter the size, a sphere is going to converge to a single contact point (with a little give due to material and pressure). But, since you can't see through the pen, you have to estimate the center of the nub when touching it to the screen. The smaller the blind spot created by the nub, the smaller the margin of error.
I bought one off Ebay for .99 delivered from China. It's a small cute collapsable pen with a thin point. I haven't tried it yet because while the tip is thin to allow precise pointing, it is also made from a hard material and I'm scared it may scratch the screen. Is that possible?
If the tip is made for capacitive screens, it should not harm the Atrix gorilla glass.
Could anything sold for under a buck from China possibly harm....Anything?
Youbetcha. As Bush and Mao both said "Trust but verify". Even a gen-you-whine Palm stylus could scrtach Palm screens, so why trust the cheapest stuff from a no-name vendor in China to be any better?
Put on a screen protector first, much cheaper than replacing the screen.

I just received the one armathrillo is describing a couple posts back and I've got to say this thing is nice. The tip is actually a soft hollow bubble. You couldn't scratch a screen if you tried. It's nice and heavy but not too heavy. It feels like a nice solid pen. The little lanyard attachment is a nice touch. It detaches from the stylus and plugs into a 3.5mm headphone jack for storage. when you're done with the stylus just clip it on and the pen stays with the phone/tab/pad.
i know this is old, but I just recently heard about the jot stylus which seems to be fine point...
Maybe this is a dumb question... but how does the S-Pen work? I read somewhere that it doesn't contain batteries but there is a button and I'm confused.
I was hoping I could find photos of it ripped apart but nothing come up on my searching.
Just an off the wall guess but I would say some kind of magnetics play a roll in its operation
Sent from the only smartphone designed by Chuck Norris
Just look up how any other Wacom system works. Long story short:
Tablet generates electromagnetic field to power stylus.
Pen uses power to create its own field, sending information (pressure, orientation...) back to tablet.
Tablet receives information and calculates pen position based on signal strength.
Actually your body generates an electromagnetic field which is conducted through the usually non magnetic metal portions of the stylus to most phones with capacitance screens. The area surrounding the button and point of the Note's S pen are magnetic though and probably use the electromagnetic field of the Note itself in conjunction with the S pen software.

No it will connect to the Prime via Bluetooth, thus allowing for pressure sensitivity and greater precision. The buttons are for the app devs to implement so that you can change from things like pen to eraser to marker without going in manually.

if its actually shown to improve accuracy on the prime's digitizer id spring for one, but not until i can see some actual screen tests
I liked the video.. People using their iPad to draw etc. It's a nice concept.. Not sure how much other use I would have for one.. I bought a prime with a keyboard because my handwriting is so bad!
Really want to know if it would work well on TF201. I am looking for something i actually can write some notes on the pad. It is what the pad is missing now for me
I don't see the point unless ASUS fix the wavy diagonal line issues. What good is a pressure sensitive pen if I can't even draw a straight line with it or any stylus?

The Jot Touch won't improve the accuracy of the TF Prime's digitizer. It uses the standard Jot Classic tips therefore it will be just about as accurate as the Jot Classic stylus. It does introduce a pressure sensitive switch and bluetooth in order to relay pressure information to applications that can read it but these won't have any impact on overall accuracy of the drawn lines.
TL;DR: The Jot Touch won't be more accurate than any other capacitive stylus on the Prime, but it will have pressure sensitivity for those apps that can make use of it.
I saw these both on Amazon and Ebay and decided to take a risk. It showed up today and I wanted to report my findings in case others are interested...
This is NOT a true S-Pen as it has no button and does not interact with the Wacom device at all (near as I can tell). It is just a basic capacitive stylus. But:
1. It is far less expensive at about $4 (true S-Pens are at least $15 from Korea on EBay and typically more).
2. It fits the silo well.
3. A side-by-side comparison shows it to be about .5 inch shorter than a true S-Pen.
4. It even will activate the capacitive touch buttons below the screen which the S-Pen will not. You do need to press harder/longer than you would think to get this to work.
5. Compared to the very rigid, pencil-like nib of the S-Pen, the tip of this feels pretty soft and flexible. It certainly feels different when doing some tasks - such as writing Graffiti input characters (which I do all the time). Not sure it is less accurate or bad in any way. Just feels quite different as the tip is soft and squishy and so there is a give in the setup that is not present at all in the S-Pen.
In some ways, this works better for me than the true S-Pen as its button gets pressed by accident some times. And the only thing I have ever used the button for was to trigger a screen shot capture and don't do that very often. The ability to trigger the touch buttons without having to switch from S-Pen to finger seems like an advantage but maybe not so much now that I have trained myself with the S-Pen.
Cheers!
Edit...
I need to add this. After only a couple day's use, this capacitive stylus has simply stopped working. No idea why. Have tried cleaning both screen and stylus tip. But the only response I get is after pressing way too hard and even then it is intermittent. So avoid these despite my original comments.
Another Edit...
I need to add this. This stylus is once again working just fine. I am not sure why. I did clean the screen this morning and perhaps that changed something. But as stated earlier I did that before without results. So the jury is still out on this one. I did, however, contact the seller on EBay and they are sending another unit free of charge.

I just bought a note 12.2 but I want a stylus pen with eraser functionality so that I can avoid manually toggling the eraser. I know that it works on Samsung apps, sketchbook and other big name software. However, Amazon's question and answer does not make it very clear if it works on smaller 3rd party apps like Lecture Notes.
Can someone test their stylus eraser and see if it works on Lecture Notes (free trial)?
Here is the stylus:

Yes, it does work on Lecture notes (full version). In settings you can enable button actions.
I don't have your stylus, but I tried with two different pens and both work very well (Lenovo ThinkPad Tablet Pen 4X80F22107 and Wacom Bamboo Smart CS-310)

I can confirm this. These pens work excellently with squid (Papyrus). If you additionally buy so-called premium features, you can also use a "true eraser" by pressing the pen button.

You do realize pressure sensitivity is determined by the digitizer in the tablet, not the pen...
The NotePro (All versions) have a sensitivity of 1024 levels. The only part of the pens that matter in terms of sensitivity is what they support. (A pen that supports, say, 500 levels, will never offer 1024.)
All Wacom pens support at least 1024 levels.
The Lenovo pen also supports 1024 levels.
Both pens have the exact same sensitivity level on this device.
Obviously the Wacom pen is designed specifically for Note devices as both the pen and the sensors are made by Wacom, whereas the Lenovo is not. I can't say if that affects usability, as I haven't tried the Lenovo pen.
Mind you, I have the regular and carbon versions of the Bamboo Stylus Feel for Note. (There are two versions of both the regular and the Carbon Bamboo Feel, (For Note and for Microsoft) and a lot of people bought the wrong one.)
I've been a Wacom (Intuos and Cintiq) user for years, So yea, I'm a bit biased. :laugh: I stuck with the brand I know. (Wacom is the professional brand for digital artists, from amateurs to Hollywood).

Well, I'm not really an expert.:laugh: I've just got a bit of experience with wacom's tech, and an unhealthy habit of wanting to know how everything works. :laugh:
That's actually ridiculously simple once you realize it. There is a difference in the various nibs (the tips), which affect the result when drawing, as well as 'paper'resistance on the screen. I don't know precisely which nibs came with which pen, but they vary in size, material and effect. I think the Bamboo Smart came with two different types of tips, which can be swapped. (That's what that silly piece of metal that looks like a weird pincer is for.)
Also, the driver on the tab is configured for Wacom pens. As such, the result with a non-Wacom pen can be a little lacking in finesse. Then again, thicker isn't always an advantage when you're sketching, but for non-precise tasks a more 'solid' line might be more preferable.

I've got the CS-400. There is only one version of the Carbon, as far as I'm aware.
It did have an offset at the beginning, had to recalibrate it. Mind you, it will always have an offset when held at an angle. The sensors work in a straight line. 1mm is fairly normal at 45º. (Also, that way you can see what you're drawing.)
The guide as to how to do that is here: http://forum.xda-developers.com/showpost.php?p=54772260&postcount=18
(I'll quote it here)
ShadowLea said:
There's two ways to go about this. The 'Viking equivalent of try this first' and the 'If that doesn't work, let's try the more technical one.'
Firstly, try giving it a good solid whack on the edge of a table. As ridiculous as that sounds (and makes you look), this does usually have an effect. Often, the nib isn't properly inserted, or sits at just the wrong angle. Brute force tends to work.
If that doesn't help, it's time for the proper technical solution. This works on pretty much any magnetic stylus with a button, including the Spen.
Requirements:
- A small flat screwdriver
- A non-cluttered room (preferably without carpets)
- The pen
- The tablet
Step 1) Carefully use the small screwdriver to pop off the button. You should be able to insert it along the side in the middle and then slide it towards the back end (where the fastener isunder the button).
The thing jumps, so be careful! (Hence the clean, carpet free room. I had to use a vacuum cleaner to recover mine once..) If the screwdriver doesn't work, try a needle or a razor (mind your fingers!).
Step 2) With the lid off, you'll see two dials.
The one closest to the tip of the pen adjusts the sensitivity.
The one closest to the cap adjusts the offset. This is the one we'll need to fix this issue. (Might as well tweak both whilst you're at it)
Carefully make tiny adjustments (and I mean really tiny) to these dials. Test it on the tab every time, you don't need to re-attach the button to test it. They go both ways, so play with it 'till you're satisfied with the result. (On my previous one I had to turn it a whole 85º, on my new one only 5º.)
Step 3) If you're happy with the result, click the button back on. It only fits one way, and needs to be inserted very much like a battery: one side first. (The side pointing towards the cap)
That's it
