Welcome to Android Central! If it persists in Safe Mode even after a reboot, then your Vol Down button might be faulty, stuck in a pressed state. That can make the phone think you want to boot into Safe Mode every time. If that's the case, use a cotton swab dipped in rubbing alcohol and clean the button area thoroughly, in case there's some gunk stuck in there that's causing it to be stuck. If that doesn't help, then bring it to a repair shop (although the cost of repair might be more than an S5 is worth these days).
