A51 Android 11 One UI 3.0 upgrade

[BabisVele93]

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.

To delete cache partition on Android 11 you either have to first connect phone to laptop with the charging cable OR connect wired headphones to the phone then carry out the normal procedure
