Step 2 Click the system bar on the Settings screen and enter the “About phone” bar.



Step 3: Find the line “Version number” and click it repeatedly until you see the “Developer mode” prompt.



At this time, return to the main interface of OPPO A59s Settings, find the system and click enter. At this time, we can find the column of Developer options and enter “Developer options”.



Finally, open the Open Developer options option and open the USB debug option at the bottom of the screen.



After the above steps, connect OPPO A59s to the computer, and the computer can detect our OPPO A59s. Sometimes, some apps with good functions, such as a marketing software quotation Sprite used by colleagues in the Marketing Department of our company, need to be used in USB debugging mode in the old version, but this operation is not required in the newly released version.
