Current Behavior

A local notification doesn't popup when the app is in background. It only shows as a white dot in the top bar.

Expected Behavior

Show the local notification in the same way as when the app is in foreground.

Code Reproduction

Started from scratch.

const channel: Channel = {
  id: "pop-notifications",
  name: "channel",
  importance: 4, // Tried also 5
  visibility: 1,
};

PushNotifications.createChannel(channel);
LocalNotifications.createChannel(channel);

PushNotifications.addListener(
  "pushNotificationReceived",
  async (notification) => {
    await LocalNotifications.schedule({
      notifications: [
        {
          id: Date.now(),
          title: notification.title as string,
          body: notification.body as string,
          channelId: "pop-notifications",
          schedule: {
            at: new Date(Date.now() + 1000),
          },
        },
      ],
    });
  }
);

Are you sure pushNotificationReceived is being called? It looks like what you see is the local notification shown by the OS, not the local notification you create inside pushNotificationReceived and it's using the default channel, which has an importance of 3.

You can assign the channel from the own notification payload with android_channel_id, see docs, or if using firebase console, there is a field for the channel too. How does your push notification payload looks like?

I can't reproduce if I create a local notification to a channel with importance of 4, schedule it for later and background the app.

Thank you very much. I needed many days to figure that out ;) But now I found out that I need to set my channel ID in Firebase as well.
