The Galaxy Z Flip 5 has only been available in stores for a week, and Samsung has already released the first security update for the class-leading folding smartphone. I’ve had my Z Flip 5 a little longer as I pre-ordered to take advantage of the, frankly, incredible trade-in offers. I cannot lie; I was pleasantly surprised when the security update landed so quickly, not least as it fixes a total of 86 vulnerabilities, including three that are flagged as critical.
