Samsung tightens PIN retry rules, risks factory reset
Samsung announced stronger lockscreen security rules for Galaxy phones and tablets in One UI 9. The new policy sharply reduces allowed PIN retries and increases temporary lock durations: after repeated incorrect PIN entries devices can be temporarily blocked for minutes to hours, and after the 13th failed attempt a permanent lock occurs that can only be cleared by a factory reset (which erases all data). The change aims to prevent brute-force PIN attacks. Google recently changed Android PIN limits as well, and biometric users remain affected because Android requires the PIN at least every 72 hours.
Manufacturer-level lockscreen policy increases device security and can cause permanent data loss on locked devices; limited direct impact on advertising/AdTech but relevant for device-access and enterprise BYOD workflows.

Key Takeaways & Evidence Grounding
- Samsung will apply new PIN retry rules starting with One UI 9.
- After five failed PIN attempts a 1-minute lock occurs; six attempts trigger a 5-minute lock; ten attempts trigger a 4-hour lock.
- After the 11th failed attempt the device is locked for 12 hours and after the 12th attempt for 24 hours; a 13th failed attempt results in a permanent lock that requires a factory reset (erasing all device data).
- Samsung says the rules are intended to prevent brute-force attacks on Galaxy devices.
- Google recently changed Android PIN rules (earlier announcement) and Android still requires the PIN at least every 72 hours even when biometrics are used.

Samsung launches One UI 9 beta for Galaxy S26
Samsung has launched the One UI 9 beta, based on Android 17, and is making it available to select Galaxy S26 series users in markets including Germany. The beta introduces new creative tools, expanded personalization options, accessibility and security improvements, and a redesigned quick-access menu that allows flexible arrangement of brightness, volume and media controls. Samsung Notes gains decorative ribbons and extra pen widths, Contacts can access Creative Studio for personalized profiles, and TalkBack functions from Google and Samsung have been merged to improve accessibility. The software also adds text-highlighting and a new warning system that blocks installation and execution of apps detected as potentially security-critical. Users must enroll via the Samsung Members app; Samsung plans a final One UI 9 release later this year with additional AI features.
Google updates Android app memory and sign-in rules
Google Play is rolling out new app quality requirements. From February 2027, apps must meet performance thresholds for dynamic memory usage, bitmap memory usage, and DEX code optimization, requiring at least 25% coverage via tools like R8. Play Console will offer diagnostics for these metrics, including out-of-memory crash filters and DEX insights, and Google will provide a Memory Limiter tool. Starting April 2027, eligible apps with user login must implement Zero-Tap Sign-In using the Android Restore Credentials API to automate login state restoration during device migration. Games are temporarily exempt from this sign-in requirement, with tailored guidance expected in 2027. Non-compliant apps may see reduced visibility or publishing capabilities, but not removal.
Samsung Galaxy S26 Ultra: Worth €1,450 for Privacy?

Samsung ships AI features across all S26 models (Now Nudge, image editing that can add objects, and three assistants: Bixby, Google Gemini and Perplexity). Hardware changes for the Ultra include a Snapdragon 8 Elite Gen 5, a camera array (200MP main, 50MP ultrawide, two telephoto modules), aluminum frame, and charging up to 60W wired/25W wireless. Pricing: S26 €999, S26 Plus €1,249, S26 Ultra €1,449. Samsung promises seven years of security and Android updates.
