Hi
I have a SM-T900 and is already with root
how can I enable to use spen?
which need to install programs?

You can not use Spen. You need a Note tab for using Spen.
are you sure? sm-p900 is possible
Sm-p900 is part of the Note series, sm-t900 is not.

It's not the pen that makes a Note a "Note," it's the display itself. From Wiki...
Wacom tablets use a patented electromagnetic resonance technology. Since the tablet provides power to the pen through resonant inductive coupling, no battery or cord is required for the pointing device. As a result, there are no batteries inside the pen (or the accompanying puck), which makes them slimmer.
Under the tablet's surface 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 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.http://en.wikipedia.org/wiki/Wacom

Here it is!
Things we now know for sure.
1. It Does not have BT.
2. It uses SPDIF out of the middle pin.
3. It has a TOSLINK 3.5mm connector for line out/ digital optical audio out.
4. It uses a PULSUS PSM702 chip and a COREDRIVER GC89C510A0 microcontroller
buy it?
now does anybody knows where i can buy the piece in picture number 3??

That would make this DIY even better!

Looks like that chip connected to the pogo dock is a coreriver SC.
http://www.coreriver.com/product-lines/top_CORERIVERmcu.html
I can make out GC89C??? so probably a midas 2.2 or 2.4 programmable microprocessor.
Looks like we will need to follow the lead from here to get a dock working properly.
Hey, Could you send me some higher resolution pictures of the board? I am specifically interested in the small chip near were the pogo pin cable gets attached to the main board. Or the numbers off of it would be good
Also, do you have access to an oscilloscope or logic analyzer? I have been trying to get a dock to play with myself, but it is taking some time

I tried reading the all thee numbers off it but it is obscured by what looks like a black marker dot. All I can read is GC89C5, I believe there are at least 3 more numbers/letters.
I do not have access to either an oscilloscope or logic analyzer.

EDIT: After a closer look and some better lighting we have a GC89C510A0
Sorry, I meant the one near the mark "U9" above VBUS +5V

It reads 0524P, Looks like a ESD chip.
If any of you actually make one of the diy versions you should sell them since i won't buy samsungs way to overpriced
for me, by me and I love you
Is there any way to extend the distance my phone can communicate with nfc devices? Right now I need to be within an inch or less it seems but I'd like to extend that to around 5 inches if possible?
Sent from my SAMSUNG-SGH-I747 using xda premium
Interesting article
In theory, yes, it could be done. The challenges are that NFC uses a relatively low frequency (13.56 MHz), which requires a longer antenna (22 meters). The second is that NFC tags are powered by the reader, so the signal at the tag has to be powerful enough to activate the electronics.
I wonder if you put the tag at the focus of a parabolic antenna if you could increase the range? I'm guessing not by much, since the power transfer is over the magnetic field (like a transformer).
wouldnt this also increase the security issues? at one inch its really hard to get the phone to detect anything unless YOU want it to..at 5 inches, a person standing next to you could do it.
I think one would have to have more turns of coil and more power, but what I don't know is if the coils are "tuned" to a certain frequency
Sent from my SGH-T989 using xda app-developers app
The coils are almost certainly tuned to the 13.56MHz radio frequency. The issue is that the power is transmitted by a magnetic field. More coils helps that at the expense of the tuning.
Check this NFC Extenders that would help

It has two NFC patch kit, one is for NFC smart phones, the other one is for NFC tags.
It could extend the NFC reading. Contact info @getsmartcard.net
OK, I understand the theory of high freq air transformers.
I also understand the price for the device is high and people do their own devices el chipo etc...
What I cannot understand why all those devices on eBay sold with a special back cover?
Doesn't the international N7100 support Wireless Charging from the box?
I looked inside the back cover of my Vietnam-made, Philippines-sold device. There are two pins on the cover directly touching another two pins near the battery compartment. The resistance between those two pins is small but above zero. And there is some kind of tick label inside of the back cover covering most of the space. Is it a kind of receiver coil?
How can I verify I need just the charger plate or another back cover too?
Thanks.

if not mistaken that is the NFC antenna and connector.

So those on-battery antennas like
http://www.ebay.com/itm/Qi-Standard...ories_MobilePhoneChargers&hash=item4170166bb8
is as addition to the Note 2?
Interesting how two antennas don't interfere with each other.
I need not NFC actually...
yes its a user made addition because Samsung is yet to announce a stock back cover with NFC and wireless charging...

Yeah, Toyota-style innovations.
Release something and let the buyers become your testers. At very maximum we can revoke and make free repairs (upgrades).
Hope not everyone be so smart to actually require free repair (upgrade).

can't find any info of the tab s4 s pen got the bluetooth features
is it really no bluetooth or Samsung saving the feature for the Unpacked event on 8/9 to launch ?
The info I've read online says there is not.

Which is great, i really don't want to charge my pen if i were to get this. That's what's been so fantastic about the note line all these years. Active pen, awesome Palm rejection, no batteries.
So is it powered? I always thought the sPen in the note was charged up when you put it inside.

No, Samsung S-Pen uses Wacom EMR technology which requires no power source

Thanks for the info. I think I was giving Samsung credit for some sort of inductive charging.
Actually was hoping it was the new one like in the Note 9, but that's you know giving Samsung too much credit to put something "new" in their tablet line.

Actually the S-Pen is powered by the electromagnetic grid under the display of the SGTS4. There is a very small electromagnetic device in the pen, which picks up power from the grid underneath the glass.
had to correct this years later:
and inductive stylus in not "powered" at all. passivly interact with the magnetic field of the device youre using it on
a bluetooth-stylus with a battery does not requere charging for regular functioning but for the bluetooth functionality like making photos. your regular stylus-activitys are not effected in any way. dont want to chard: dont use the bluetooth function so you dont need it. the stylus itself is passive
Hi guys, I have a Pad5 with the original pen, when I use the tablet with the magnetic cover folded on the back (with the magnet that touch the right back spot near the pen charger zone), the pen stop working, the buttons on it still work (the pen remains connected to bluetooth) but the tablet doesn't take any input. Is this a common problem?
I had Pad 5 but didn't have any similar issues. yet. I think you should check the guide
