The latest Android 8.1 comes with a bunch of small modifications, many of which we saw on the recently-released Pixel 2 and Pixel 2 XL. These include an automatic dark theme, a revamped power menu, and the ability to see battery levels for connected Bluetooth devices in Quick Settings. But the latest update also brings some new improvements with it, including one that’s been expected for long: a limit to the number of notification sounds an app can generate in a second.
It might have happened that your phone greets you with tons of notification sounds when you turn it on after being powered off for a while. Facebook’s Messenger is an extreme offender in this case. The app produces various different notification sounds, and when you receive multiple messages while offline, the sounds turn into a dissonance that can last several seconds.
Now Google is putting some limitations on how many sounds an app can generate in quick sequence. According to changes in the Android developer documentation spotted by Android Police, apps running on Android 8.1 can only generate one notification sound every second. Here’s the relevant paragraph:
Apps can now only make a notification alert sound once per second. Alert sounds that exceed this rate aren’t queued and are lost. This change doesn’t affect other aspects of notification behavior and notification messages still post as expected.
In case if it’s not clear, this change doesn’t mean notifications will be lost. You will still receive them and can view in the tray, but the annoying sound won’t be there anymore.
