Samsung is rolling out the December 2021 security update to these phones and tablets, bringing One UI 4.0 and Android 12 to some devices.
Samsung has begun rolling out the latest Android security update for December 2021, and, for some Galaxy phones, the update is arriving as part of the update to One UI 4.0 and Android 12. As usual, the rollout of the December 2021 update for Samsung Galaxy devices began just before the new month even arrived, on November 30, a full week before Google released notes on the Android update. According to Google’s original bulletin, there are 5 critical,21 high-priority, and 3 moderate issues fixed in Android’s December 2021 patch. Since then, Samsung has released their own detailed manifest of the Security Maintenance Release, which supplements Google’s fixes with a variety of Galaxy-specific patches. Most of the “Critical” fixes are for issues specific to Exynos devices, while another interesting exploit allowed Apps Edge to work even when your phone is supposed to be locked. Beyond the usual security fixes, the December 2021 update is arriving as part of the more important update to the Android 12-based One UI 4.0, for some Samsung devices like the Galaxy Z Fold 3. Before the month of December even got started, Samsung began rolling out the latest security update, though certainly not as quickly as in recent months. As is usually the case, Samsung rolled the update out first to some of its most expensive phones, the line of Galaxy Z foldables. Year after year, the Galaxy S series has been the essential Android phone to own, serving as one of the strongest and most popular competitors to Apple’s iPhone.
