What’s new with the Samsung September 2021 security update?

Samsung started rolling out the security update to most of their Galaxy devices from August 30. Google used to be the leader when it came to bringing out updates to their Android phones. However, Samsung is now consistently releasing its security patch ahead of Google. This is one of the reasons that Samsung is fast becoming known as the king of updates. This month is no different.

This is a whole week ahead of the first Monday in September when Google usually starts rolling out their security patch. Google’s rollout was further delayed as the first Monday in September coincided with Labor Day in the United States.

After looking at the security patch from a Samsung-specific angle, two notable changes come with the September security update for certain devices. The first is the issue between a few Galaxy devices and Android Auto. Google promised that the July security patch would fix this problem; however, that was delayed. It would seem that this issue is finally resolved with the release of the September update.

Another notable change with this latest update is that certain Galaxy devices such as the S20 FE and the Z Fold are receiving an update to One UI with the September security patch. Galaxy phones that do receive this update will also gain the benefits of the One UI 3.1.1. This includes changes to the phone app and the new bedtime mode toggle from the quick settings menu. Some of these features of the One UI may be device-specific.

Here is a list of all the Samsung Galaxy devices that have received the September security patch to date:

  • Galaxy S20 FE - August 30
  • Galaxy S20 FE 5G - August 30
  • Galaxy Z Flip - August 31
  • Galaxy Z Flip 5G - August 31
  • Galaxy Z Fold 3 - 31 August
  • Galaxy S10 Lite - September 3
  • Galaxy A8 - September 4
  • Galaxy Note 20 - September 5
  • Galaxy Note 20 Ultra - September 5
  • Galaxy S 21 - September 6
  • Galaxy Fold - September 6
  • Galaxy A52 - September 6
  • Galaxy A72 - September 6
  • Galaxy Note 10 - September 7
  • Galaxy M21 - September 7

Closing words

Samsung is setting itself apart from the rest by releasing regular Android security updates for its mobile devices. The Galaxy devices are among the first to regularly receive the latest security patch, even before Google releases theirs.

    Meanwhile, they routinely ignore/forget their older devices such as my Samsung Galaxy A6. July security patch? Meh. Mine is still sitting at May.

    Maybe they’ll eventually get around to it next year. Maybe.

    I wish I’d get that battery protection feature from the foldables on my N20U. It limits the charging to 85%. I always end my days with over 40% battery, so I really don’t need the battery to charge to 100%.
