Here is what the page “iPhone Call Quality Fixes: Improve Audio and Connection Stability” contains. If your iPhone calls sound muffled, drop frequently, or you struggle to hear the other person, a few simple adjustments can often restore clear, reliable audio. Common culprits include obstructions in the receiver mesh, Bluetooth routing issues, and software glitches that affect call stability. Start by cleaning the earpiece and microphone openings with a soft, dry brush to remove dust and debris. Next, check your audio routing: during a call, tap the speaker icon to ensure audio isn’t being sent to a disconnected Bluetooth device.
Toggling Airplane Mode or restarting your iPhone can also resolve temporary network or software hiccups. For persistent problems, navigate to Settings Accessibility Audio/Visual and disable Phone Noise Cancellation, which sometimes muffles voices. You can also try enabling Wi-Fi Calling in Settings Phone if cellular reception is weak. This listing links straight to the original page, where the content is available in full.
