During phone calls the phone ear speaker produces the hum/buzz sound (known from a cellphone being placed next to an external speaker) for the complete time of the phone call. This sound is also heard by the receiver of the call on his telephone. Changing the sim card to another provider did not solve this problem. Also setting the network from 4G to 2G did not solve the problem. Signal strength is above 50% or much higher. This sound is not heard when making a phone call e.g. via Whatsapp.
