Android notification icons
The current app notifications on android are not ideal. They are either a blank square or a square in a circle. It would be great if we were able to edit what icon the app uses when displaying notifications.

Android notification icons provide quick alerts and updates from apps, helping users stay informed. These icons vary based on system settings and app permissions, some of which can be accessed through the Android Hidden Menu for deeper customization and troubleshooting. Exploring this menu allows users to adjust system notifications and optimize their device experience.
