I have been managing with a 2014 Blackberry phone for everyday life and work, it fits in the side pocket of my work trousers.
I have recently opened a business bank account that needs a smartphone with Android 10 or above to use their mobile app.
I bought a new phone with a 6.5 inch screen so it is a lot bigger than the Blackberry but I really do not want to damage it or get it wet, bent in my pocket, fall out of my pocket when bending over etc while at work.
I am traditional so wear a full width pouch and a BOAB.
I can leave it in the glove box of the vehicle but it would be handy to have on me to answer calls and texts.
Do you have your phone on your person all the time when working?
