1. Update the system: Make sure that your one plus Pro is running the latest operating system version. Go to Settings-> System Update Check if there are any available system updates. Installing the latest system updates may provide more features and options.
2. Use the search function: use the search function in the setting interface to find other advanced setting options. There is a search box at the top of the settings interface, where you can enter keywords or phrases to find options related to the advanced settings you want.
3. Open the Developer Options: Some advanced settings may be hidden in the Developer Options. To open the developer options, follow these steps:
-Go to Settings.
-Scroll to the bottom of the page and click "About Phone".
-Find the "version number" and click it 7 times in a row.
-Go back to the previous setup interface and you will find new "developer options". There may be some advanced setting options.
4. Reset application preferences: Sometimes, some options in the settings may be disabled or hidden. You can try resetting the application preferences to solve this problem. Go to Settings-> "Applications and Notifications", click the three-point menu in the upper right corner and select "Reset Application Preferences". After restarting the device, check whether other advanced setting options appear in the settings.
5. Restore the factory settings: If the above methods can't solve the problem, you can try to restore the factory settings. Please note that restoring factory settings will delete all data and settings, so please back up important data in advance. Go to Settings-> "system"->; "Reset Options", select "Restore Factory Settings".
If you still can't find other advanced setting options through the above steps, I suggest you contact the official customer service support, who can provide you with more professional guidance and support.
