Durability

I just wanted to ask you to share experiences about durability.
My current phone has lasted me almost 5 years
And for the first time I think I made a good investment.
And still feels it can lost 2-3 more years

But my eyes would really appreciate having a bigger screen like the z fold

And I think Samsung makes the better hardware

But my fear is to invest that much money in something is not durable

And waiting on insurances and Samsung care feels scary

Thank you for sharing
