🔈 Common Sound Issues on Phones
- No audio in calls or media playback
- Voice recorder not capturing audio
- Headphones plugged in, but no sound

- Static, muffled, or distorted sound
🛠️ General Fixes (Android & iPhone)
🔹 1. Restart Your Phone
Rebooting clears temporary system glitches that may affect audio services.
🔹 2. Remove the Case or Cover
Some rugged cases block microphones or muffle speaker output. Remove it and test again.

Dust or lint can clog your speaker/mic. Use:

- A SIM ejector pin (gently)
🔹 4. Check Volume Settings
Go to Settings → Sound
Make sure:

- Silent Mode or Do Not Disturb is turned off
📱 Android-Specific Fixes
🔹 5. Safe Mode Test
Reboot in Safe Mode to check if third-party apps are causing the issue.

Go to Settings → Apps → [Media App] → Storage → Clear Cache

Dial *#0*# → Tap Speaker or Mic test to check if hardware is working (may not work on all models)
🍏 iPhone-Specific Fixes
