I have a galaxy s21 ultra, and 2 windows machines. 1 windows 11, the other 10. Right now I've got my ultra synced with my windows 11, but when I work on my windows 10, can I also sync it up with that?
Yup, it's pretty neat! And if you just care about texting, you could use apps like Pulse (that have apps for nearly every device out there and could make an app for toasters if they wanted to) or the free, simple option of Google Messages. That lets you use the app on your phone, now (finally!) tablet, and any device with access to a web browser.
