I am on a Galaxy S7-edge (hero2lte), one of the refurbished, pre-/e/-installed phones. I received my first OS-system update notification last week … just now I noticed that a 2nd update became available a few days later, too.
I have not yet applied either update. Are there any caveats or concerns about installing system updates? Are they reasonably safe to apply immediately upon notification, or might they be buggy? Are these updates device-specific, or are they /e/-system-wide updates? Is there a bullet-list of included bug-fixes and updates somewhere?
