Samsung Ends Software Support for Galaxy Note 20 Series, Raising Security Concerns
Samsung has officially ceased software updates for the Galaxy Note 20 and Note 20 Ultra, leaving users vulnerable to emerging security threats. The August 2025 security update represents the final patch for the popular models, which originally launched with a promise of three years of Android OS updates, followed by quarterly security updates.
the end of support means the devices will no longer receive critical security fixes for newly discovered vulnerabilities. While the Note 20 series received its last major OS update in 2023 with One UI 5.1 (based on Android 13), ongoing security patches are vital to protect against evolving cyberattacks. Google’s September Android security update, for example, addressed several critical vulnerabilities already being exploited, fixes the Note 20 series will not receive.
Although minor system patches may occasionally arrive through the Google Play Store,these do not address deeper firmware-level vulnerabilities. This leaves users exposed to risks that are challenging to mitigate. Samsung has, in the past, issued emergency patches for select models, but users should now consider their devices highly vulnerable.
Experts recommend against storing sensitive details, such as banking credentials or password manager data, on unsupported devices. The safest course of action is to upgrade to a newer smartphone model that continues to receive regular security updates.
The Galaxy Note 20 and Note 20 Ultra were praised for features like their microSD card slot and MST payment technology, features still missed by many users.
