Porsche Cayenne strange noise heard during phone calls, stops when the car is stationary on Porsche Cayenne

Some Porsche Cayenne owners report experiencing strange noises during phone calls that cease when the car is stationary. These noises may be attributed to a poor network connection, where a weak or fluctuating signal leads to white noise, particularly when the vehicle is in motion. Additionally, faulty phone hardware, such as damaged or outdated components, could also contribute to the issue, as movement may exacerbate the problem. Interference from the car's electrical system or external factors may further affect phone signal quality, with variations depending on the car's movement and surroundings. To mitigate these issues, owners are advised to check for a strong network signal, update phone software, inspect hardware for damage, and consult a professional technician if the problem persists.
