The S Pen is an inductive stylus. The display on the Note has what’s called an active digitizer under the glass. When the S Pen gets close to the screen, the magnetic field of the active digitizer induces a current that powers its internal circuitry. This…. is the Note 7 S-pen. The brand new stylus from Samsung fits inside The Note 7 Smartphone. Its little plastic tips are supposed to mimic a real-life pen as you write electronically on the screen of the phone, and the whole thing is water-resistant.
Just like the phone itself. So let’s do what we always do… and see what makes this thing tick. There are a few improvements over the Note5 S-Pen. The two main differences are that the tips are finer on the Note 7, or pointier, and The Note 7 S pen can detect twice as many pressure levels. So your artwork, or penmanship will look and feel more realistic. Included in the box are replacement tips, just in case, something happens to the originals. There are two types of material used for that.
The white plastic is slightly more brittle than the included grey rubber-type tips. Replacing the tips is easy enough. Pop-out the little metal tweezers that are included in your box and just give the tip a little pull. Then the replacement tip can be slid into place. I imagine that the rubber tips will leave slightly less of a grove in plastic screen protectors. Since they are a bit softer. But time will tell. So how does the S-Pen Work? Let’s find out what is inside. The whole thing is water-resistant, and permanently sealed, so there are not any easy access points.
The usual breaking things in half approach seem to work just fine. Now that we have identified that the weakest point on the S-Pen, which is right below that plastic chrome clicky part. . A few people have complained that their S-Penhas stopped clicking. Which means that it gets stuck inside the phone. This doesn’t seem to be widespread though. With Millions of phones being shipped a few are bound to be defective. The spring mechanism inside is pretty much identical to any other style of clicky pen that you can buy at the store.
A few springs, and the rotating plastic piece. Remember, since this pen is not made to be taken apart, if anything breaks on it, or if it stops working… the only option is to replace it. Fixing is not an option. I will link replacement pens and replacement tips down below in the article description if you need them. The shaft of the pen is sealed by plastic. There is no easy access point here either, so we are going to have to crush it away if we want to see what’s inside. After crushing it open with my pliers, we expose the mainboard, and before we look at that, let’s look at the tip.
Now to me, this is the most interesting part of the pen. These coils of wire. As we’ve seen from the teardown article thus far, there are no power sources inside the S Pen. So how does it receive its power and communicate with the Phone? These coils here are the main event. If you remember from my invisible wireless charging desk article, Wireless charging does not need direct contact in order to work. These copper coils in the phone will still charge through thin objects.
When we look at the pen, we can see that even before the pen touches the surface of the phone, it is already receiving inductive power through those coils in the tip. And the digitizer, inside the phone, has already detected the electromagnetic field in the tip and is ready for the contact of the pen. The mainboard in the S-Pen has covered ina thick rubber coating.
This is probably another layer of waterproofing. Under that layer is a ton of resisters that I imagine help out with the 4000 different levels of pressure detection. Which is quite an improvement over the 2000levels of pressure detection in the Note 5 S pen. I do not believe that this S Pen is a prime candidate for a reassembly article. Otherwise, it is just another stylus that most people won’t appreciate or use often enough. If you have note 9 you can quickly jot notes like if you had a notepad and pen. The S Pen even acts as a remote for controlling your camera with gestures, playing music and media, and flipping through presentation slides.
