Audio & calls

Phone audio sounds choppy or robotic during calls

This usually points to weak cellular signal, network congestion, or a Bluetooth codec issue rather than a broken phone. Moving to better signal and checking Bluetooth settings often resolves it.

Symptoms

  • Voice sounds broken up into small pieces
  • Sound has a robotic or metallic quality
  • Problem is worse when moving or driving
  • Clears up when call is restarted

Likely causes

  • CommonWeak or fluctuating cellular signalChoppy audio is a classic sign of a marginal signal area or moving between towers.
  • CommonNetwork congestion during peak hoursHigh call volume in an area can degrade voice call quality.
  • PossibleBluetooth connection interferenceOther wireless devices nearby can interfere with a Bluetooth audio connection.
  • PossibleWi-Fi Calling switching networks mid-callMoving between Wi-Fi networks or from Wi-Fi to cellular can cause brief choppiness.
  • Less commonCarrier-side technical issueA problem on the carrier's network equipment can affect call quality regardless of your phone.

What to do

  1. Check your signal strength and try moving to an area with more bars or near a window.
  2. If using Bluetooth, move closer to the connected phone and away from other wireless devices like microwaves or routers.
  3. Turn off Wi-Fi Calling temporarily and test the call over cellular only, or vice versa.
  4. End the call and redial to establish a fresh connection.
  5. Restart the phone to reset its network and Bluetooth connections.
  6. Check for and install any pending software or carrier settings updates.
  7. Ask the other caller if the choppiness is on their end, since it could be their connection.
  8. If the issue happens consistently in the same location, report it to your carrier as a possible coverage gap.

When to call a pro

If choppy audio happens consistently in good-signal areas or on all calls, contact your carrier to check for network issues.
