Hey guys, welcome to our channel!
In this video, I will show you how to reset all settings on the oppo A12 smartphone without deleting any saved data and media files.

ColorOS Reset System Settings Only
Aside from a factory reset, Oppo devices also offer other reset options that do not affect any saved information on the phone. Among these options is the reset system settings only.
As the name implies, this reset only erases all custom system settings and does not affect any saved data and media contents on the device. This reset is often recommended before resorting to a factory reset when dealing with complex system issues.

Important Note:
Before you begin, your phone must be sufficiently charged to ensure that the entire reset process will be completed. The phone’s operating system could end up corrupted if the reset isn’t finished or gets interrupted.

This method is also applicable to other OPPO devices with the same ColorOS or OS version with the OPPO A12.
