Method and system for detecting the presence or absence of a protective case on an electronic device

An electronic device for detecting the presence of a protective case on the electronic device, the electronic device comprising:

• one or more sensors;
• a device memory storing an application including programs instructions for performing a method for detecting the presence of the protective case;
• a device processor coupled to the device memory and the one or more sensors, the device processor, upon execution of the application, being configured to:
• monitor, via at least one first sensor of the one or more sensors, a trigger condition for detecting the presence of the protective case;
• detect the trigger condition;
• in response to detecting the trigger condition, cause the electronic device to vibrate for a pre-determined period of time;
• collect, via at least one second sensor of the one or more sensors, sensor data during the pre-determined time;
• extract at least one feature from the sensor data;
• based on the extracted at least one feature, determine whether the protective case is applied to the electronic device;
• and
• generate an output indicating whether the protective case is applied to the electronic device.
