I am (and this thread is about) talking about the Fairphone 6.
The last update for the Fairphone 6 is from July and includes the Android security patch from June.
It’s not that some carriers or countries don’t receive updates for the Fairphone 6. There was no update for the Fairphone 6 since the July update.
Here LINK is a thread that started about the Fairphone 4 (!) not receiving security patches in a timely manner that has since evolved into a thread talking about the 4, 5 and 6. To me it sounds like the security patches for the Fairphone 4 and Fairphone 5 were on average (in the last 3 years) arriving about 3 - 4 months late (which is not acceptable). So I fear that this is not a one-off problem since July for the Fairphone 6 but the usual modus operandi for Fairphone.
