When the proximity sensor on your OnePlus 15 stops working during calls, the screen may stay on while the phone is against your ear. This can lead to accidental taps, muted calls, or even hanging up without realizing it. The issue is usually caused by simple software settings, sensor obstruction, or calibration problems, and most of them are easy to fix.
Why Your OnePlus 15 Proximity Sensor Is Not Working
- The proximity sensor is blocked by dirt, a case, or a screen protector.
- A software glitch occurred after a system or app update.
- Display or accessibility settings are interfering with the sensor.
- The Phone app cache has become corrupted.
- The sensor needs recalibration.
1. Clean the Proximity Sensor Area
The proximity sensor sits near the top of the screen and can stop working if it is covered. Dust, fingerprints, or thick screen protectors are common causes.
Turn off the screen, and then wipe the top portion with a clean microfiber cloth.
Remove any case or screen protector temporarily, and then test the sensor during a call.
2. Restart Your Phone
A restart refreshes system services that control sensors. It also clears temporary bugs that may affect call behavior.
Press and hold the Power key, and then tap Restart.
Wait for the phone to boot up fully, and then make a test call.
3. Check Display and Accessibility Settings
Some display or accessibility options can keep the screen active during calls. These settings may override the proximity sensor.
Open Settings, and then tap Accessibility.
Check interaction or display-related options, and then turn off anything that keeps the screen awake.
4. Clear the Phone App Cache
If the Phone app is not responding correctly, the proximity sensor may not trigger during calls. Clearing the cache often fixes call-related issues.
Open Settings, and then tap Apps.
Tap Phone, then tap Storage, and clear the cache.
5. Test the Proximity Sensor
Testing the sensor helps confirm whether it is responding at all. This can tell you if the issue is software-related or possibly hardware-related.
Open the dialer, and then enter the diagnostic code provided by OnePlus.
Run the proximity sensor test, and then check if the screen turns off when covered.
6. Reset App Preferences
Resetting app preferences restores default behavior without deleting personal data. This can fix conflicts caused by modified app permissions.
Open Settings, and then tap Apps.
Tap Reset app preferences, and confirm the action.
If none of these steps work, the proximity sensor on your OnePlus 15 may have a hardware issue. In that case, contacting OnePlus support or visiting an authorized service center is the safest option to avoid further problems during calls.
FAQs
Why does my screen stay on during calls on OnePlus 15?
This usually happens when the proximity sensor is blocked or when software settings interfere with sensor behavior. Cleaning the sensor area and checking settings often resolves it.
Can a screen protector affect the proximity sensor?
Yes. Thick or poorly aligned screen protectors can block the sensor and prevent it from detecting when the phone is near your ear.
How do I know if the proximity sensor is broken?
If the sensor fails diagnostic tests and does not respond even after software fixes, it may be a hardware issue that requires professional repair.
