Then you go back for warranty? Depends on the manufacturer and country of course but in the EU 2 years is the minimum and some member states extended that
I once had a phone break just shy of 2 years and got it repaired, lasted three more years after and I only had to replace it because apps started to require a newer OS, the hardware was fine
On the other hand, the iOS device I had for a few years at work broke part of the touchscreen just after 2 years (nice one, Apple, just out of warranty) and had a battery life that was bad from day one, but then I only use it twice a day for 2FA and the occasional call so it wasn't quite worth sending back
YMMV... saying that any phone running a particular OS must have hardware lasting no longer than the minimum warranty period is beyond me. Well, except when there is only one manufacturer's monoculture of course
