In actual use, when the electronic device is in a call state, the call can be connected by hand, or through an auxiliary call tool, such as a Bluetooth headset. When using the normal call mode to realize the call, the auxiliary call mode can be enabled to realize the call. The method for switching the antenna feed point provided by the embodiment of the present application is aimed at the situation that the electronic device is connected to the call by holding it. Therefore, when the electronic device is in the call state, the step of obtaining the user's ear image may include:

When the electronic device is in a call state, determine whether the electronic device is currently in a handheld state;
