The new software update for Galaxy M01 is rolling out in India. It is bundled with firmware version M015GXXU3BUH1. As of now, we don’t have the complete changelog, but the new build does not bring anything other than just a new security patch. The July 2021 security patch for Samsung phones fixes over a dozen of vulnerabilities to improve system security and privacy. The update has already started hitting Galaxy M01 Indian units. It may take few days to reach all the units. Meanwhile, you can manually check for the latest update by heading to Settings » Software updates.
Galaxy M01 was launched last year with Android 10 out of the box. Thanks to one major Android OS upgrade, the phone is running Android 11. We’ll have to wait and see if the Galaxy M01 makes its way to the Android 12 eligible devices list. [source]
