Well done for ignoring my question and answering a completely different one.
Yes my phone runs Android. But the screen is smaller, and I actually like to save my battery for, you know, making phone calls.
If you're going to be carrying a Switch with you anyway, it'll be an objectively superior experience to use that over your phone for just about any activity from gaming, to spreadsheets,to watching movies, to remote control of computers. The only thing that I can imagine it wouldn't be better for is navigation, due to the lack of GPS
