Wouldn't have a 'smart' phone if you gave me one!
Can't stand the things.
On the train, bus, in restaurants, in pubs banging out stupid videos or tinny crappy music.
What makes people think that everyone wants to listen to their conversations, the commentary on some football game, or a cat video?
As well as calls/texts as per usual with a phone I use mine for loads of other things....
Work sheets/debtlists
Card payments off customers 
Online banking
Social media
Cleanitup
Youtube
Porn
Paying bills
Online shopping 
Music/radio/audio books
Camera/video
News/weather
Calendar/notes/calculator 
Maps/navigation 
NOW TV(football)
TUI holidays app
Email
Files for theatre tickets/bills etc
Watch(tracking heart rate/steps)
Ordering prescriptions 
Ordering takeaway food and booking restaurants 
Torch
Google pay using phone 
There's probably others but these are the main ones....
I absolutely love my smartphone...its more like a phablet....I only use my laptop for the main cleaner planner site and printing off invoices these days...🙂
