How to Fix Samsung Galaxy Proximity Sensor Not Working During Calls

A Samsung Galaxy proximity sensor not working during calls is usually fixed by removing anything blocking the top sensor, checking call-related settings, updating the system, and running sensor calibration or diagnostics. If the screen stays on during a call on Galaxy devices, the most common causes are a dirty sensor area, a case or screen protector misalignment, software glitches, or failed sensor calibration.

Steps

Clean the sensor area near the front camera and earpiece. Dust, oil, or a thick screen protector can block the sensor. Remove the case and protector temporarily, then test a call again.
Restart the Galaxy phone and install pending updates. A temporary system bug can affect call behavior. Open Software update in Settings and install the latest Samsung firmware.
Run the built-in sensor test. Open the Samsung diagnostic menu if available or use the Members diagnostics tool. Check whether the proximity sensor changes status when a hand covers the top front area.
Reset accessibility and call-related settings. Features that change touch behavior can interfere during calls. Review settings related to accidental touch protection, accessibility interaction controls, and call screen behavior.
Calibrate or reset settings if the sensor still fails. On supported models, use sensor calibration from diagnostics or service settings. If no calibration option appears, reset all settings to clear corrupted system preferences without deleting personal files.

Common Issues and Fixes

Issue	Likely Cause	Fix
Screen stays on during calls	Blocked sensor	Remove the case, remove or reseat the screen protector, and clean the top bezel area.
Sensor test does not react	Software fault or hardware damage	Update firmware first, then test in Safe Mode to rule out app conflicts.
Problem started after screen replacement	Poor alignment or non-original part	Inspect the display fit and have the sensor assembly checked by service support.
Issue appears only in one calling app	App bug or permission problem	Clear the app cache, update the app, or test with the default Phone app.
Sensor works sometimes	Pocket lint, moisture, or unstable calibration	Dry the device fully, clean the earpiece area, and repeat sensor calibration.

Quick Tips

Protector damage: A cracked protector over the earpiece area can trigger a false screen on during call Galaxy problem even when the display looks normal.
Safe Mode check: Safe Mode is useful when the issue began after installing call recording, overlay, or screen filter apps.
Physical damage risk: Samsung proximity sensor fix attempts may fail on models with physical sensor damage after drops or liquid exposure.
Calibration limits: Sensor calibration is not available on every Galaxy model or One UI version.

🤔Note:

If the proximity sensor stopped working right after a screen replacement, hardware alignment is a strong possibility and software fixes may not fully solve the issue.

💡Protip:

Test calls with both the default Phone app and Safe Mode before resetting settings, because this quickly helps separate app conflicts from deeper system or hardware problems.

Why does the Samsung screen turn on when the phone is near the ear?

The proximity sensor may be blocked, miscalibrated, or failing. A case, protector, software bug, or bad screen replacement is often responsible.

Does resetting the phone fix proximity sensor problems?

A settings reset can fix software-related sensor behavior. A full factory reset should only be considered after updates, diagnostics, and calibration checks fail.
