and then they break it and decide the cost of a repair isn’t worth it

Yep, that was me with my previous phone, which I did indeed have for over 5 years.

But there’s another major factor to it.

I use Android phones, which get official software updates for only a couple years (3 years for the most part). This includes security updates.

So when I got my current one it was one of only two I even considered, because only those two manufacturers promised 5 years of (security) updates at the time.

It has gotten better though, but except for Fairphone they’re still all very hard or impossible to repair.

It’s at the very bottom of the settings page inside the app itself.

Mine vanished as well, but after I added it back it now works fine again.
