Hi!
I forgot this post was even still up, haha.
Since writing my initial post, I have learned a bit more about the situation.
As it turns out, Galaxy watches seem to be mostly, if not fully compatible with tablets.
In the Wearables app, there is a function that checks what type of device you have, to determine what you can connect to.
Since this is a simple flag in software, it is possible to trick the app into thinking your tablet is a phone, and voila!
You can now connect to your watch with seemingly full functionality, minus any phone-related activities that the tablet itself does not support.
I’m not sure why Samsung refuses to allow their watches to connect to tablets, but unless I’m missing something, it seems like an incredibly easy thing for them to enable.
