Some owners say their phones briefly lose Wi-Fi and Bluetooth when they unlock the device or bring up the Lock Screen. The quick disconnects break wireless CarPlay and can cause AirPods to skip or drop audio. That combination explains why wireless CarPlay blips and why Bluetooth audio stutters. The issue often happens only when an Apple Watch is on the user’s wrist and unlocked. If you rely on wireless CarPlay or Bluetooth accessories, test a device before finalizing a return or taking a long trip.
