How to disable notifications

I want to turn off all app pings on my phone but can

Before you proceed with what appears on your surface as a straightforward system-level configuration change, it is absolutely imperative that we establish a comprehensive taxonomy of notification delivery vectors because "notifications" is a categorical umbrella term and treating all channels uniformly would be a catastrophic analytical error. We must bifurcate our approach into four distinct domains: native OS push notifications (which involve the FCM/APNs multiplexing layer), browser-based web push via Service Worker registration, desktop application level polling or WebSocket subscriptions, and what I call "ghost notifications"—those that occur at the API response level but never reach a UI element. Each of these requires an entirely different intervention strategy because changing one without accounting for others creates a false sense of completeness while leaving silent data channels active in the background.

Let us address native OS push first. On modern Android, this is managed through the NotificationManager and AlarmManager subsystems where each app registers with specific channel IDs (ANOTIFY_CHANNEL_ID) that carry their own importance levels from MIN to MAX. If you want a blanket disable, your option is system-wide permission revocation via Settings > Apps & notifications > App info, but I strongly advise against this because it will break critical functional channels like calendar alerts and call callbacks which share the same delivery subsystem as your social media marketing spam. A more surgically precise approach is per-channel configuration where you can set each notification type to "Silent" instead of disabling entirely—this still delivers the data payload but bypasses heads-up display logic, sound triggers, and lock screen rendering while preserving the ability for the system to perform background fetch operations when appropriate.

Now consider the web push vector which is frequently overlooked by casual users. If you have opened a website that requested notification permission in your browser (Chrome, Firefox, Safari all maintain separate vendor-specific databases), that permission persists across OS settings because it lives at the renderer process level not the system level.
