Shortly after Google released the patch on Tuesday, September 8, Samsung has already distributed the September Android security update to its flagship models.

According to Android Police, as of Tuesday, some versions of Samsung's Galaxy Note 8, Note 9, Note 10, Note 20, Note 20 Ultra, S10, A21, A51, and A70 have received Samsung's general software update as part of Samsung's general software updates, which vary from country to country, but they had already received the update.

Bleeping Computer reported yesterday (September 9) that some Galaxy S10 5G also received the update.

Google's September Android security bulletin lists over 50 security bug fixes, some of which are considered "critical." The "most serious" one, according to the preliminary report, is a flaw in the Media Framework that could allow malicious files to enter the device. There are five other critical flaws in phones using Broadcom chips.

Many of Samsung's top-end phones, including all Galaxy S, Galaxy Z, and Galaxy Note phones released in the past three years, receive monthly security updates. Mid-range phones receive quarterly updates, and some flagship models older than three years are relegated to quarterly updates for an additional year of support. Samsung Mobile's website has a complete list of which Samsung models are on which update schedule.

However, Samsung phones will not get an upgrade to Google's next mobile OS, Android 11, any time soon. It rolled out Tuesday on Google's own Pixel phones. Certain OnePlus, Oppo, RealMe and Xiaomi phones will all get final beta versions, but not Samsung's model.

Your Samsung phone should flash a screen notifying you that a software update is available. If you want to check manually, go to Settings > Software Update or Settings > About Device > Software Update, depending on your model.
