The answer seems obvious, of course, and I’ve been in IT for 20+ years so I’m not clueless. OTOH, don’t know much about phone tech anymore.

I almost never use the phone for browsing or email, mainly texting, calling, pictures and navigation. So what are my threat vectors? If I’m not on the web or downloading sketchy apps, what risks am I looking at?

I ask because I just got an old Pixel 4a and was wondering how long I’ll get updates.

EDIT: I should add that I don’t connect to any wireless but my own.
