Samsung has enhanced the security of its Galaxy phones with One UI 9, making them significantly more resistant to brute-force PIN attacks.

• Successful 13 incorrect unlock attempts will permanently lock a device, requiring a factory reset.
• This new security policy was introduced with the Galaxy Z Fold 8 and Galaxy Z Flip 8.
• One UI 9 now features a countdown timer to clearly display lockout durations and treats consecutive identical incorrect PIN entries as a single failed attempt to prevent accidental lockouts.

Leaked One UI 9 builds for the Samsung Galaxy A57 and Galaxy A17 5G suggest that Samsung is expanding its Android 17 beta testing program.

• The leaks indicate development progress for One UI 9 on mid-range and budget devices, a shift from previous beta programs focused on flagships.
• Samsung is preparing for a wider public beta for its popular A-series phones.
• The Galaxy A57 build features a security patch dated August 5, 2026, ahead of its official release.

A leaked timeline suggests Samsung's One UI 9 update will begin rolling out to Galaxy S26 and Galaxy S25 series devices in late August to September.

• The alleged timeline indicates One UI 9 will ship pre-installed on new Galaxy devices in early August.
• This information reportedly comes from Samsung Customer Support via a Samsung Members community post.
• Older Galaxy flagships, Galaxy A series phones, and tablets are expected to receive the update in late 2026.
