The following are OS-specific settings for Zenfone devices that may affect notifications.
Battery Optimization
Notifications may not work properly if any power saving mode is enabled, or if power usage is managed in the background.
- Android phone Settings > Battery > turn off Background app management.
- Android phone Settings > Battery > Auto-start Manager > ensure Signal auto start is allowed.
Display notification icons
This will change how notifications are displayed in the status bar. If this is set to "None" you will not see app icons for notifications in the status bar.
- Android phone Settings > Apps & notifications > Display notification icons > “3 most recent” will only show notifications from Signal in the status bar if it was one of the last 3 notification alerts on your phone.
- Android phone Settings > Apps & notifications > Display notification icons > “Number of notifications only“ will only show a number in the status bar instead of app specific icons.
New notifications
If “New Notifications - Wake screen when you receive notifications” is toggled off the device will have an audible alert and vibrate but will not wake the screen when a new notification arrives.
- Android phone Settings > Display > New notifications should be enabled.
