Patent number: 11966288Abstract: In an electronic apparatus, a processor executes a program stored in memory to perform essential functions. In the event of an error related to these functions, a self-test application is triggered. The processor may identify a relevant test routine from a set of routines, conduct tests on the function using the identified routine, and communicate the test results to a display. Accordingly, when an error occurs while the electronic apparatus is operating, the electronic apparatus can inform a user and a manufacturer of a cause of the error.Type: GrantFiled: February 10, 2022Date of Patent: April 23, 2024Assignee: Samsung Electronics Co., Ltd.Inventors: Jaehoon Kim, Sungjun Kim, Kyuseon Son, Seunghee Shin, Myunggyun Yoon, Youngchang Lee
