There are a lot of tools on life, that make it more convenient, that aren't required to survive. Like a hammer for example.

phones are pretty convenient though. even just having a camera and gps in one small device is nice.

For day to day activities? No, you probably don't need GPS and camera.

I gave up my smartphone a decade ago. It's only "inconvenient" when people expect me to have internet in my pocket.

I don't _need_ it but using a smartphone instead of navigating via a physical map and taking photos of memorable events throughout the day sure is nice.

The car has a map + navigation already, and I care very little about documenting events... although I do use the phone during tear downs for the purpose. Still the prime use of the (my) phone is actual phone calls.

Smartphones aren't only for social media.
