Smartphone (even an older model) to help with daily tasks (Cowley OX4)

I’m looking for a working smartphone as I am still using a very basic, old-style mobile phone and it’s becoming increasingly difficult to manage daily life without one. Between working long hours to cover high rental costs and managing some health-related sight issues, having access to apps for transport, , health matters and basic navigation would be a huge help. I know this is a big ask, but if anyone has upgraded recently and has their old phone sitting in a drawer, I would be very grateful to give it a second life. It doesn’t need to be fancy – just a standard, functioning smartphone would be amazing.Thank you for reading.
