Method 1. Restore factory settings
This is the initial method you should employ whenever you cannot identify why your Oppo phone is running slow. So, try reading the article on restoring factory settings on Oppo that we previously provided on Mytour.vn to see if it can completely resolve the slow performance issue on your device.
Note: Before restoring the factory settings of your Oppo phone, make sure to back up the data on your device to avoid losing all the data stored on the phone.
Method 2. Perform software reset
If you have tried method 1 and your device is still running slowly, then the last option you should consider is performing a software reset, updating the Oppo phone's firmware. This action will bring the device to a new and clean firmware just like when you first bought it.
