I saw someone used their old phone as part of their desktop with shortcuts. Is that what you call a companion? I'm really curious about that. What else can it do?

Do you think it's possible to convert it into a storage cloud, something like that. That I don't have to pay for online storage and get my photos and videos stored?

A phone lasting 6 years is really impressive as you had said.

I always wait for a bit before I get a newer model. Never buying it during the launch.

I don't really trust to secondhand ones because as careful as I am, there tend to be some minor accidents. It probably happened more often to others.
