🔈 Common Sound Issues on Phones

🛠️ 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:

Go to Settings → Sound
Make sure:

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