On top of those, Samsung has added 11 more fixes for security loopholes in Galaxy smartphones and tablets. That takes the total security fixes included in Samsung’s March 2023 security patch to 50. Five fixes are critical, while 35 are marked ‘high.’ Most of the Samsung-specific bug fixes are marked as ‘moderate’ priority."
