✅ [SOLVED] WhatsApp Notifications Not Showing — Hidden Culprit: App Icon Badges
📌 Problem:
WhatsApp notifications completely stopped — no sound, no vibration, no pop-ups.
This happened right after I disabled **"Sound & Vibration"** in the notification settings.
Later, the option disappeared from the UI, and no matter what I did, **I wasn't getting any notifications** for a whole day.
🛠️ What I Tried:
I connected my device via ADB and attempted various resets — permissions, notification listeners, etc.
I avoided uninstalling WhatsApp because I wanted to retain all chat data.
💡 Root Cause Identified:
After trial and error with another non-critical app, I discovered the issue:

Since Turning off sound and vibration option silently disables pop-up notifications too.
So :
Re-enabling **App Icon Badges** instantly brought back the option and all WhatsApp notifications — sound, vibration, and heads-up banners.
🧩 Final Fix:
> Go to **Settings → Notifications → App Icon Badges → Enable it *you can see changes in notification settings*.
📎 Notes:
- ADB can help test/reset notification settings, but in this case, it was a **UI-level toggle** causing the problem.
- Even after resetting everything via ADB, **App Badging** was the key to restoring full notification behavior.
