Grafana OnCall has released improvements for its Android mobile app to enhance the experience of on-call engineers by optimizing notification delivery, especially in overcoming the complexities of Android's Do Not Disturb (DND) modes. Unlike Apple's straightforward notification handling, Android's varied settings and OEM differences complicate ensuring critical alerts are both seen and heard. Previously, the app would adjust ringer modes and volume settings, inadvertently allowing all notifications to bypass silent mode, which was disruptive. The new approach utilizes the alarm sound channel, which bypasses silent mode without altering user preferences for other notifications, ensuring critical alerts are audible without unnecessary disturbances. This update, part of the 1.15.1 release, reflects Grafana's commitment to improving user experience and invites feedback from users to continue refining the app.
