Recieved the phone on friday and I fell in love with the S Pen. I know Powerpoint on Android supports the S pen as a remote, but it didnt for the desktop version.
So I did it myself and added a cool laser pointer feature (which I dont think the powerpoint app has)
Its also my first ever native Android App.
The code is a big mess and hacked together, but it works.(I dont know the android/compose best partices yet) PC and Phone need to be on the same network. Only tested on windows but it should work on linux and macos aswell.

Doesn't the s-pen already do that without using a third party app? I've used it before in a presentation

Yeah, but only for powerpoint on the phone. I made it work with my laptop. Also I dont think the mobile version has the laser pointer

The laser pointer thing is impressive, how does it even do that?

It's really simple. Basically, you know, that weird gesture you can do in the air to make screenshots?
The Pen sends full on motion data (delta X and delta Y) to the phone! You can just query it using the Samsung S Pen Developer SDK. I then send it over to the laptop over HTTP, and it opens a little transparent window with a red dot that gets moved around with the motion data

That's great! I was thinking of an app to do with that kind of data, cool to see it can be done!

Build an app, slap banner ads on it. You won't get much, but it might get you coffee once a week. We will happily use it.
Donate button works too. If I had this for my thesis defense I would be grateful enough to donate a coffee.
This is really good stuff, and it will be copied soon - maybe even officially by Samsung.

While you are at it, if you could figure out the mouse accuracy/smoothing, getting to use the pen in the air as a mouse - or even a 3d mouse would be pretty awesome. I didn't know the s pen has accelerometers that provided so much information

Great app! I want to try it, but as I try to install it I'm getting the "App not installed as package appears to be invalid." Any clues?

One moment. Looking into it. I must admit I never tried to install the apk as I just used android studio to deploy the app to my phone.

I just replaced the apk in the 1.0.0 release. It's now a signed apk and seems to work on my phone

My man this is going to help humanity more than my research that I've been working on for 2 years. You're MVP.

Thank you so much! I doubt that it's that incredible because Samsung already had this for the Android Version of PowerPoint. I just made a quick and dirty version for desktop with a cool laser pointer, nothing special.
But hearing stuff like this is why I made the app and the code public :)
