I have the Fairphone 4 and I’ve been very happy with it. It’s not as fast as the top models, but I have no use for a fast phone and every app I need works perfectly. It’s been such a relief knowing I don’t have to buy a new phone because the battery or the port died. And I tend to drop my phone regularly, so it’s great that I can switch out the screen. I’ll definitively buy another Fairphone when the time comes.
The transfer into proton is indeed very easy and with their family pack you also get Mail, Drive, VPN, Calendar and they keep working on adding more. Very happy with proton and their fight for privacy
