Vulnerabilidades fixed in April package

The update brings fixes for security flaws identified in the Android core and the One UI 8.5 interface. The package acts directly on loopholes related to the permissions system of third-party applications, blocking unauthorized access to sensitive resources on the device. Além Additionally, privacy settings for biometrics and facial recognition features receive significant improvements.

The stabilization of background processes is also part of the update, reducing battery energy consumption during continuous operations. Wi-Fi 7 and Bluetooth connectivity gain improvements in high-interference scenarios, ensuring more consistent performance in congested urban environments. Essas optimizations contribute to more fluid operation during daily use.

• Correção of critical holes in the application permissions system
• Atualização in privacy settings for biometrics and facial recognition
• Estabilização of background processes to save battery
• Melhoria on Wi-Fi 7 and Bluetooth connectivity in interference environments

Especificações technical models Galaxy S26

The Galaxy S26 line uses high-performance components compatible with Android 16. The Ultra model features the Qualcomm Snapdragon 8 Elite Gen 5 processor, optimized for generative artificial intelligence and intensive processing tasks. The standard and Plus versions employ the Exynos 2600 chipset, which balances graphics power with thermal efficiency for extended use.

Dynamic AMOLED 2X panels offer variable refresh rate up to 120 Hz and peak brightness of 2,600 nits, providing exceptional visibility outdoors.
