When the proximity sensor stops working during calls, your screen may stay on. This can lead to accidental taps, muted calls, or even dropped connections.
If this is happening on your Galaxy S25 Ultra, the issue is usually tied to settings, obstructions, or sensor calibration. Let’s go through the fixes step by step.
Why the Proximity Sensor Is Not Working During Calls
- Screen protector or case blocking the sensor area.
- Accidental disabling of sensor-related features.
- Temporary system glitches affecting call behavior.
- Phone app misconfiguration or outdated software.
- Dirt or oil covering the sensor area near the earpiece.
Clean the Proximity Sensor Area.
The proximity sensor sits near the front camera and earpiece. Even a thin layer of dirt or oil can interfere with how it detects your face during calls.
Wipe the top front of the phone using a clean, dry microfiber cloth. Make sure there are no fingerprints, dust, or smudges around the earpiece area.
Remove or Adjust the Screen Protector.
Some screen protectors are not properly cut for the sensor area. This can prevent the screen from turning off when the phone is near your face.
Remove the screen protector temporarily and make a test call. If the sensor works normally, replace it with a protector designed specifically for the Galaxy S25 Ultra.
Enable Accidental Touch Protection.
This feature helps the phone manage screen behavior when it detects close contact. It can improve how the screen reacts during calls.
- Open Settings, and then tap Display.
- Tap Accidental touch protection, and then toggle it on.
After enabling it, make a call and check if the screen turns off properly when held to your ear.
Check the Phone App Settings.
If the Phone app is misbehaving, the proximity sensor may not trigger correctly during calls. Reviewing its settings can help restore normal behavior.
- Open the Phone app, and then tap the three-dot menu.
- Tap Settings, and then review call-related options for anything unusual.
If you changed call settings recently, revert them to default and test again.
Restart the Phone.
A simple restart can clear temporary system issues that affect sensors. This refreshes background services used during calls.
Swipe down from the top-right of the screen to open Quick Settings, then tap the Power icon. Tap Restart, and then confirm the action.
Once the phone boots up, place a call and test the proximity sensor again.
Update the Software.
Sensor bugs are sometimes fixed through software updates. Keeping your phone up to date helps ensure proper hardware behavior.
- Open Settings, and then tap Software update.
- Tap Download and install, and then follow the prompts if an update is available.
After updating, restart the phone and test the sensor during a call.
If the proximity sensor starts working again, you’ll notice the screen turning off instantly when the phone is near your face. This prevents accidental touches and makes calls feel normal again.
FAQs
How can I test if the proximity sensor is working?
Make a call and place your hand over the top of the screen near the earpiece. If the screen turns off, the sensor is working.
Can a phone case cause proximity sensor issues?
Yes. Thick cases or cases with raised edges near the sensor area can interfere with detection. Removing the case can help confirm this.
Does a faulty proximity sensor mean hardware damage?
Not always. Most issues are caused by settings, software, or obstructions. Hardware failure is rare but possible if none of the fixes work.
