How to Check Android Security Patch Level

Find the installed date

Open Settings and the device or software information screen, then locate Android security update or security patch level. Menu names vary.

Understand the date

The patch level names the bulletin level included in the build. Installing today does not necessarily make the displayed date today.

Compare carefully

A bulletin describes fixes available to manufacturers; it does not prove a particular model or carrier build received them.

Write down four separate values

Open Settings, tap About phone (or About tablet), then Android version. Google's Android Help lists the Android version, the Android security update date, the Google Play system update and the build number on that screen. Menu names vary by manufacturer. Record the four values separately: a changed app version does not show that the system patch changed, and the Play system update is not the same date as the Android security update.

Look for an update for your own variant

To check for software, open Settings, then System, then Software updates, and follow the on-screen instructions. Google says update schedules vary by device, manufacturer and mobile carrier. Compare a release only when it matches your model code and market; a bulletin or build for another variant does not prove that your phone should have received it today.

Update the Android version first

Google advises having the latest Android version available for your device in order to receive the latest security update available for it. Pixel phones install downloaded Android updates in the background and the update becomes active after the next restart. Many other Android phones restart automatically while installing. After installing, reopen About phone and read the patch date again.

If no update appears

Check the connection and the manufacturer's update instructions. A phone that is not offered a package does not by itself prove that support has ended, because rollout can differ by model and carrier. If the question remains, ask the manufacturer or carrier using your model code and build number; do not post your IMEI or serial number publicly.

Connect the patch date to the support record

Find your exact model in the device directory and compare the scope of its source with your phone. A support end date, an OS-upgrade promise and the latest documented build answer different questions, and a date calculated from a policy is not a guaranteed day for a patch to arrive.

Worked examples from the catalog

Use the model identifier and jurisdiction together; a marketed name alone is not enough. These records show how the method is applied to real evidence.
