OPPO Find N3 Flip Screen Does Not Wake After an Unconnected Call
What Happens?
After an unconnected call, the screen may turn black
The display does not wake up automatically
The phone continues to function normally in the background
Pressing the Power button immediately turns the screen back on
Why This Happens
The OPPO Find N3 Flip is designed with smart protection features to prevent accidental touch input:
The device uses an ultrasonic proximity sensor during calls
If a call is not connected, the phone may enter a locked or screen saver state
Covering the screen with a large area (such as your hand) triggers pocket mode detection
The system then places the phone into sleep mode to avoid unintended actions
This behavior helps protect your device when it’s placed in a pocket, bag, or enclosed space.
Is This a Problem?
No. This is normal system behavior:
The device is working as designed
No hardware or software damage is involved
Display functionality is unaffected
What You Can Do
Simply press the Power button to wake the screen
Avoid fully covering the screen immediately after an unconnected call
Use With Confidence
Your OPPO Find N3 Flip is operating normally. This design ensures better protection against accidental touches and enhances overall device safety.
