Yes, and I love it. After practice it’s much faster than regular typing, although you do need to proof (in my experience). I wish there was a swipe-typing course like there are typing courses.

We use WhatsApp for work because our team is international. Personally I just use whatever that is native on my phone. It usually works.

I have (obviously) an SE 2020 and because I work at home and hardly go anywhere I can live with charging it all the time. Like OP, I don’t need anything fancy.

Also, for work, I wanted a lowest common denominator phone (small) so I could see what our customers with small phones are seeing.
