Google is now rolling out the September 2021 Android Security Patch to all Pixel devices.
This is the monthly security update that Google sends out to its devices and it shares with its partners. It doesn’t include any new features, just security fixes. However, next month will feature the latest Pixel Drop, and will likely be bundled in with the release of Android 12.
We have actually already seen this patch roll out to some other smartphones from Samsung, ahead of Google actually announcing the patch.
What’s been fixed in this patch?
Google fixed a ton of vulnerabilities in the June 2021 security patch for Pixel and other Android devices.
As per usual, Google has not detailed each vulnerability. This is done on purpose so that those that have not received the update (which right now, is everyone) is not the victim of an attack. Detailing the vulnerabilities is like giving the keys to hackers, to your device. So this is done to protect everyone. But there are a ton of changes made to Qualcomm and MediaTek devices, as well as vulnerabilities in the Android Runtime and more.

What devices are supported in the September 2021 security patch?
The September 2021 security patch is rolling out to Pixel devices now. And it supports the Pixel 3, Pixel 3 XL, Pixel 3a, Pixel 3a XL, Pixel 4, Pixel 4 XL, and Pixel 4a. The Pixel 4a 5G and Pixel 5 should both come with the September 2021 security update installed when they go on sale later this month. If not, there should be an update available out of the box.
The Verizon versions of the Pixel 3, Pixel 4 and Pixel 5 will be rolling out later this week.
Most smartphones released in the last two to three years will also be supported. You’ll need to wait for your smartphone manufacturer to roll out the update though.
Make sure to update your Pixel device as soon as you get this update, and don’t put it off. Security updates are not great for putting off til later on.
