Fairphone has never previously provided full security patches for anywhere close to their promised support. The Fairphone 4 doesn’t currently receive proper security support but rather receives the Android Security Bulletin patches consistently 1-2 months late and many of the recommended patches (Pixel Update Bulletin) years late.
Fairphone 4 does not include a secure element and does not provide many of the expected hardware security features. It also has a broken/incomplete implementation of verified boot and attestation.
Are these issues fixed with recent Fairphones?
EU law makes it a requirement to provide updates since a company stops selling the device. So they better fix it or they will be sued.

There can be updates pushed out while not addressing this issue.
