Phone "Proximity Sensor" Not Turning Off Screen During Calls
4.5
Your face accidentally presses buttons (like Mute or Hang Up) during a call because the screen stays on.
Symptoms
- Screen stays on during calls
- Accidental button presses
- Face-dialing
Possible Causes
- Dirty sensor
- Software glitch
- Hardware failure
Step-by-Step Fix
1
Test in Voice Memos
Record a memo and hold the phone to your ear. The screen should turn off.
2
Remove Thick Case
Some cases have a lip that reflects the infrared light back into the sensor.
3
Calibrate with App
On Android, use "Proximity Sensor Reset" apps to recalibrate the hardware.
When to See a Technician
The proximity sensor uses infrared light; if the glass is scratched or dirty, the light can't "see" your face.
