Because the system software interacts with the apps on the phone. Even if there's no flaw in the apps, a system-level flaw can have different manifestations depending on what happens to be where in memory, which can depend on the apps.
My guess is a single firmware flaw is causing all of the failures where some component (such as fps or iris scanner) stops working periodically but recovers right away when you reboot (or sometimes the phone reboots itself when the component stops working). I would also guess that if Samsung hasn't fixed it by now, they never will. Sales are still going ok, so they can just keep quiet and ride it out.
