If you are afraid of hardware malfunctions, may I propose the Fairphone?

It is literally designed so you can replace the hardware yourself. USB-C port broken? 15€ and 10 minutes later you have a new port (even if you don’t know anything about phone repair). Screen broken? 80€ and you have a complete new one. Battery replacement is 30€ and that is just pop-and-go like in the old days.

They also give at least 5 year warranty, and you can still buy parts for the Fairphone 2, which is about 7 years old at this point.
