Moi? I use currently a NOTE 20 ultra 5g. Probably my second best phone, I only hate the fact it’s so massive (I miss being able to use just one hand for my phone) and the mediocre battery life for someone like me that watches a lot of videos. But the S pen is so handy those few times you need it.
Fairphone also has 5 (!) year of warranty if you sign up for free.
And you can still buy all the spare parts for the Fairphone 2 which came out 9 years ago.
So getting to 8 years shouldn’t be a problem.
