Samsung tightens phone security: 13 pin attempts before factory reset

Samsung is dramatically bolstering the security of its Galaxy devices with One UI 9, implementing a significant shift that will undoubtedly impact user experience. The update, already rolling out to the Z Fold 8 and Z Flip 8 families, drastically reduces the number of PIN attempts allowed before a dreaded factory reset is triggered.

A crackdown on brute-force attacks

Previously, users were afforded a generous 20 attempts to unlock their handsets before a factory reset kicked in. However, that system relied on a toggleable ‘Auto Factory Reset’ setting, a feature rarely activated, leaving users vulnerable to persistent brute-force attacks. Cellebrite, a specialist in mobile forensics and data recovery, leverages techniques like brute-force cracking to bypass phone security, highlighting a real-world threat.

The problem? That default disabled setting meant practically unlimited tries. Each incorrect entry extended the lockout period, creating a frustrating, albeit somewhat effective, deterrent. But the days of that casual guessing game are over. With One UI 9, the ‘Auto Factory Reset’ is now mandatory, limiting users to a mere thirteen attempts to enter the correct PIN.

The cellebrite factor

This change directly addresses the concerns surrounding devices like Cellebrite’s machines – tools capable of systematically testing every possible combination to unlock a phone. Samsung’s move represents a proactive defense against such sophisticated attacks, acknowledging the evolving landscape of mobile security threats. It’s a calculated risk, prioritizing security over user convenience.

The Galaxy S26 series, currently running beta 4, is expected to receive the enhanced security measures in September. While a minor inconvenience for the average user, this restriction underscores a serious commitment to protecting user data, particularly in an era where mobile devices are increasingly targeted by malicious actors. Samsung’s not seeking to irritate their customer base; they’re simply erecting a stronger barrier – one that, frankly, is long overdue.

Trade-in deals are available for the new Z Fold models, offering up to $1,200 off the Galaxy Z Fold 8 Ultra and $1,200 off the Galaxy Z Fold 8, making the investment slightly less daunting. But the real value lies in the enhanced security – a quiet, yet vital, upgrade that speaks volumes about Samsung's evolving approach to mobile protection.
