Good evening,
On February 25th I upgraded my device to the latest version (Android 11 / One UI 3.0), the country of origin is Malaysia and that's probably why the upgrade came earlier. But I have two or three problems. Samsung's social networking in Contacts does not work, I can not have both SIMs permanently activated and now you can not access the Fast Boot menu to delete the cache partition.
Plus I have done factory reset 2 times and it still has the above issues.
Anyone who encounters something similar or knows it, will be happy to read in the comments.
