I'm on my smartphone right now! Far too many to count - I email, make phone calls, look at files for work, have games on there, constantly use the calculator and I don't remember what I did before they invented the banking app! I even use my phone as a camera, spirit level and calculator.
I like simplicity and have deactivated most of the aps the phone came with. Of course I use it as a phone, on rare occaisions I may send a text (not often, I prefer to talk to people), I use the calendar, somestimes the calculator, the contacts, and if there is no other alternative the internet. I keep it to a minimum becasue I only have a $34 a month phone package.
Send and receive SMS, make phone calls, use calculator and calendar, use camera, turn data on to download pics family send me and off to save battery drain, a couple of shortcuts I've set on my home page and Peppa Pig concentration card game I have for my 3 year old grandson.
