How to Use Diagnostics to Monitor Your OPPO Phone’s Health
Your OPPO smartphone includes a tool called Diagnostics within the Phone Manager app. Think of it as a health check center for your phone. Whenever your device acts up—like the touchscreen not responding or other unexpected issues, you can run Diagnostics to inspect various parts of the system and get a report of what might be wrong.
What Diagnostics Can Do
It checks components of your phone (e.g. touchscreen, sensors, battery).
It shows you which parts are working well and which might have problems.
You can run selected checks or full checks depending on what issue you’re facing.
You get a report at the end, and you can act on the suggestions.
How to Run Diagnostics
1. Open the [Phone Manager] app on your OPPO device.
2. Tap the three-dot icon (or “:” / “⠇”) in the top right corner.
3. Select [Diagnostics].
4. Choose which items you want to test (e.g. touch screen, sensors, battery).
5. Tap [Run diagnostics].
6. Follow the on-screen instructions. You can skip some tests if you want.
7. After the tests complete, a detection result report appears.
8. Use the results to fix or adjust settings based on what the report shows.
Note: The check items are divided into two main categories: Auto check items and Manual check items. During the manual detection, you need to follow the instructions prompted on your phone's screen.
How to View Past Diagnostics Reports
Inside Diagnostics, tap the same three-dot icon (or “:” / “⠇”).
Select [Records] to see earlier test results. This helps you track how your phone’s components have changed over time.
Why Use Diagnostics
Catch small issues before they become big ones.
Know exactly which component is failing.
Save time when explaining issues to service technicians.
Decide whether a repair is needed or just a software reset.
When to Use It
When the screen is unresponsive.
If sensors like proximity or accelerometer aren’t working.
When battery life drops suddenly.
Before you bring your phone for service, to collect data.
What Diagnostics Can’t Do
It won’t fix hardware failures by itself.
It may not detect every kind of software bug.
If a component is damaged (e.g. after a drop or liquid exposure), Diagnostics may only show failure but can’t repair the damage.
