A forensic investigator I know stated, "Even with UFED, it may not be possible to decrypt secure folders after Galaxy S21, even with Live extraction formats such as QualcomLive, ExynosLive, etc. or full file system extraction formats for Exynos chip targets. He stated, "There is a possibility.
He also stated that "it does not matter what kind of CPU you have, and KnoxVaut may be affected.

If the screen lock is engaged, does the secure folder have to be unlocked again?
