They advert for a support between 8 and 10 years (at least 5 major version of Android, and security patches after that). I don’t know their politic about the availability of the repair parts, but if it’s for the same amount of time, I’ll be happy.

I changed the battery and the usb port of my OP7 last year… the oneplus site didn’t sell them anymore, I had to go on aliexpress to have both … That’s quite frustrating for a device that is 5 years old…
