In mid-November 2025, a new app called “Mainline services” was released as one of the “System Services” system apps required for the Android platform to function correctly.

The “Mainline services” app actually manages the “Google Play system update,” which is part of the broader “Google System Updates” that include new features to enhance the security and reliability of Android devices. Previously, “Google Play system updates” were checked for under Settings > Security & privacy > System & updates on Android devices. However, with its release as the “Mainline services” app, it’s now also possible to check for “Google Play system update” distributions from the “System Services” settings.
