What the proximity sensor does and why you might want to disable it

Your phone's proximity sensor is a small infrared light that detects when your face is close to the screen — usually during a call. When it senses your face, it turns off the display and disables the touchscreen so you don't accidentally tap things with your cheek. On most phones, this sensor works automatically and you never think about it.

You might want to disable it if the sensor malfunctions and keeps the screen dark even when you're not on a call, or if you use your phone in a way that confuses the sensor — like holding it at an odd angle during video calls. Some people disable it temporarily to test whether a screen problem is caused by the sensor or something else.

The catch: you cannot fully disable the proximity sensor on most phones through settings. What you can do is turn off the feature that responds to it, or work around the problem if the sensor itself is broken.

Key Takeaways

  • Most phones do not have a direct "off" switch for the proximity sensor in settings — the sensor itself stays active.
  • You can disable the feature that uses the sensor by turning off "Proximity Wake" or "Proximity Lock" in your phone's accessibility or display settings.
  • If the sensor is physically broken and keeps your screen dark, covering it with tape is a temporary fix, though it may affect face unlock features.
  • Restarting your phone or clearing the cache of your phone app often fixes a sensor that is stuck or behaving oddly.

Turning off proximity sensor features in Android settings

On Android phones, the proximity sensor is usually controlled through accessibility settings rather than a dedicated sensor menu. Open Settings, then go to Accessibility. Look for an option called Proximity Wake, Proximity Lock, or Disable Proximity Sensor — the exact name varies by manufacturer and Android version.

If you cannot find it in Accessibility, check Settings > Display and look for Screen Timeout or Advanced Display Settings. Some Samsung phones have the option under Settings > Advanced Features. Toggle the setting off if you find it. If your phone does not have this option, the sensor is likely always active and cannot be disabled through settings alone.

After you change the setting, test it during a phone call to see if the screen now stays on when your face is near it. If the screen still goes dark, the sensor itself may be malfunctioning rather than the software setting.

Disabling the proximity sensor on iPhones

iPhones do not offer a built-in setting to disable the proximity sensor. The sensor is part of the Face ID system on newer iPhones, and Apple does not separate it into a standalone control. If the sensor is causing problems during calls, your options are limited to hardware fixes or workarounds.

One workaround is to use speakerphone during calls so your face is not near the screen. Another is to use headphones or a Bluetooth device, which removes the need to hold the phone to your ear. If the sensor is physically broken and you need a permanent solution, you would need to have the phone serviced by Apple or a certified repair shop.

What to do if the proximity sensor is stuck or broken

If your screen stays dark during calls even after checking settings, the sensor itself may be malfunctioning. Before assuming it is broken, restart your phone — this clears temporary software glitches that can cause the sensor to behave oddly. Power off completely, wait 10 seconds, and power back on.

If restarting does not help, try clearing the cache of your phone app. On Android, go to Settings > Apps > Phone, tap Storage, and select Clear Cache. On iPhone, you cannot clear the Phone app cache directly, but you can force-close it by swiping up from the bottom of the screen (or using the app switcher on older models) and swiping the Phone app away, then reopening it.

If the sensor is physically damaged or the problem persists after these steps, a temporary fix is to cover the sensor with a small piece of clear tape. The sensor is usually a small dark dot near the top of the phone, above the screen. Tape will block the infrared light and prevent the sensor from detecting your face, though this may interfere with Face ID on iPhones or other face-based features.

Why you might not want to disable it permanently

The proximity sensor saves battery life by turning off the display when you are not looking at it. During a 10-minute call, this can add up. Disabling the feature means your screen stays on the entire time, draining the battery faster.

On iPhones with Face ID, the proximity sensor is part of the same hardware system that unlocks your phone with your face. Disabling or covering the sensor can slow down Face ID or cause it to fail. On Android phones with face unlock, the same issue applies — the proximity sensor and face unlock often share the same hardware.

Testing whether the sensor is the problem

If you are not sure whether a dark screen during calls is caused by the proximity sensor or something else, you can test it. During a call, hold your hand a few inches above the top of the phone without touching it. If the screen turns back on, the sensor is working. If the screen stays dark, the sensor may be broken or the software setting is still active.

Another test: open the Phone app and pretend to make a call (do not actually dial). Slowly move your hand toward the top of the screen. A working sensor will turn the display off as your hand gets close. If nothing happens, the sensor is not responding.

Frequently Asked Questions

Can I disable the proximity sensor without affecting Face ID?

Not on iPhones — the proximity sensor and Face ID hardware are integrated, so disabling one affects the other. On Android phones with separate sensors, you might be able to disable the proximity sensor feature without affecting face unlock, depending on your phone model.

Will covering the sensor with tape damage my phone?

Clear tape over the sensor will not damage the phone itself, but it may interfere with Face ID or face unlock features. The tape blocks infrared light, so the sensor cannot detect your face. Remove the tape if you want those features to work again.

Why does my proximity sensor keep malfunctioning during video calls?

Video call apps sometimes override the proximity sensor settings, keeping the screen on so you can see yourself. Check the app's settings for an option like "Keep Screen On" or "Disable Proximity Lock" and turn it off if you want the sensor to work normally during video calls.

Is the proximity sensor the same as the light sensor?

No. The light sensor measures brightness and adjusts your screen brightness automatically. The proximity sensor detects how close your face is to the phone. They are separate sensors, though they may be located near each other at the top of the phone.

What if my phone does not have a proximity sensor?

Older phones and some budget models do not have a proximity sensor. If your phone did not come with one, there is nothing to disable. You can check your phone's specifications online or in the manual to confirm whether it has the sensor.
