Over the last couple of months, Samsung has done a fantastic job of releasing security updates for its devices. Following the rollout of the Android security patches for December 2020 last month via beta channel, the company delivered updates for the Galaxy S20 FE, Galaxy S9, Galaxy Z Fold 2, Galaxy Note 10, Galaxy XCover Pro, and the Galaxy S20 series with the December 2020 patches. Now, the Korean OEM has started rolling out updates for the Galaxy Note 20 and the Galaxy S10 lineup.

Galaxy Note 20

The December 2020 security update for the Exynos 990-powered Note 20 5G (model number SM-N981B) and the Note 20 Ultra 5G (model number SM-N986B) with the firmware version N98xBXXS1ATK1 is now rolling out in several European countries. Interestingly, a slightly newer build with version number N986BXXS1ATK4 for the Ultra variant is available in the "SEB" region, which is Samsung's code for the Baltic countries.

Judging from the version number, the new build doesn’t carry any significant new feature except the obvious bump in the Android security patch level (SPL). The company is expected to release the equivalent update for the Exynos 4G and Snapdragon Galaxy Note 20 variants in the coming weeks.

The global variant of the Galaxy S10 is now receiving the December 2020 security patch update in a bunch of regions. This new build is tagged as G97xFXXS9DTK9 and comes in at about 123MB in size. Just like the case of the Galaxy Note 20 series, it is a typical security maintenance release.

Samsung has yet to publish the details of the December 2020 security bulletin on their site. The updates are rolling out in batches, but you can skip the queue and download the new firmware packages directly from the Samsung update server using Frija or Samloader.
