In this article we will show you how to fix ‘iPhone proximity sensor not working’ issue. During a phone call, your iPhone uses the proximity sensor to detect the presence of your face, ear, and cheek. Your iPhone does this because of two main purposes: Reduce display power consumption and thus save battery life by turning off the screen light and to disable your iPhone’s touch screen to avoid inadvertent and unwanted inputs by your face.

The proximity sensor on the iPhone is a very user-centric feature. It aids in automatically turning off the screen when we answer a phone call and place the device to our ears. In addition, a malfunctioning proxy sensor may result in some unwanted taps on the iPhone’s display, which can be aggravating. The failure of the proximity sensor in a mobile device is an issue that nearly every user encounters.

But for now, let’s concentrate on the iPhone proximity sensor fix. We’ve compiled a list of solutions that can be used to get the iPhone functioning properly. This is one of the primary functions of the proximity sensor on the iPhone. It can detect when your phone is close to your body and automatically turn off the screen to prevent accidental use during a call and conserve battery life. We mentioned below are the ways how to fix ‘iPhone proximity sensor not working’ issue.

What is the iPhone proximity sensor?

A proximity sensor enables the detection of nearby objects without physical contact. Proximity sensors used in iPhones are optical sensors. The proximity sensor can determine the distance between our skin and the phone or any other object. This feature disables the Touchscreen when a phone call is received and the device is held close to the ear to prevent accidental input.

To illustrate, suppose you’ve observed that when you answer a call and place the phone to your ear, the screen turns off. To prevent accidental touches during phone calls. It also serves other purposes, but its primary function is to disable the display during phone calls. Consequently, if the proximity sensor on your iPhone isn’t working, it can be quite annoying!

Causes of iPhone Proximity Sensor not working Issues

1. Interference from Screen Protectors: Low-quality or improperly aligned screen protectors may impede the proximity sensor’s functionality. Consider removing the screen protector or repositioning it.
2. Software Bugs: Occasionally, iOS software bugs can affect the performance of the proximity sensor. Updating your iOS software and performing a software reset (restart) can assist in resolving these problems.
3. Faulty Hardware: If the proximity sensor itself is damaged or malfunctioning due to physical damage or manufacturing defects, it may need to be replaced by a professional technician.
4. Certain third-party applications: may interfere with the proximity sensor’s operation. Uninstall recently installed applications to see if the problem is resolved.
5. In certain instances: the proximity sensor may need to be recalibrated. This is typically accomplished through the phone’s settings or via specialized apps.
6. Water Damage: Moisture or water can harm the proximity sensor and other internal components if they are exposed to it. If your phone has been submerged in water, it may need to be repaired or replaced.

How to fix ‘iPhone proximity sensor not working’ issue

Execute hard reset

1. Press and hold the “Home” and “Sleep/Wake” buttons simultaneously for over 10 seconds.
2. When Apple logo shows on your phone screen, release both buttons.
3. Unlocking your phone with a PIN code will allow the proximity sensor to function normally.
4. The communication between iOS and proximity sensors is not always seamless. This method could reconstruct the connection and reunite them.

Update software

1. Connect to a secure Wi-Fi network or enable cellular data via the “Settings” application.
2. To back up your iPhone, navigate to “iCloud” > “Backup” and then select the “Backup Now” option. You can also back up your iPhone using third-party software.
3. Then, navigate to “General” > “Software Update” in the “Settings” application. If a software update is available, tap “Update and Install Now” and follow the on-screen instructions to complete the update.

Restore iPhone to factory settings in DFU mode

1. Connect your iPhone to your computer via cable and launch the most recent version of iTunes.
2. Hold simultaneously the “Sleep/Wake” and “Home” buttons for at least 10 seconds. Then, release the “Sleep/Wake” button while continuing to press “Home” until iTunes displays the recovery mode message.
3. Click “OK” on the iTunes message, then navigate to “Device” > “Summary.” Click the Restore iPhone button on the right panel to restore the iPhone to its factory settings.

Restart iPhone

1. When the proximity sensor on your iPhone is not functioning, press and hold the “Sleep/Wake” button to turn off the screen. It is located on the right side of the iPhone.
2. Once the slider is moved to the right, the phone will immediately shut down.
3. After your phone’s screen has completely turned black, press and hold the “Sleep/Wake” button until the Apple logo appears.

Importance of a working proximity sensor

1. User Experience: Proximity sensors improve the user experience by enabling convenient and intuitive device interactions. For instance, when you bring your smartphone close to your ear during a phone call, the proximity sensor detects this and turns off the display to prevent accidental touch input, which not only conserves battery life but also prevents unintended actions.
2. Energy Efficiency: Proximity sensors save energy by automatically dimming or turning off displays and backlighting when a user is not actively interacting with a device. This characteristic is prevalent in smartphones, tablets, and laptops, where it extends battery life.
3. In automotive collision avoidance systems: proximity sensors play a crucial role in terms of safety. They can detect obstacles or nearby vehicles and activate warning systems or even automatic braking systems to prevent collisions.
4. Accessibility: Proximity sensors are integral to the design of interfaces accessible to people with disabilities. They enable gestures and controls that do not require physical contact, making it easier for individuals with limited mobility or dexterity to interact with devices and technology.
5. Proximity sensors are utilized: extensively in industrial automation and robotics. They are able to identify the presence or absence devoid of objects. This improves manufacturing processes’ productivity, effectiveness, and safety.

Conclusion

Attempting all the solutions above means you’ve tried enough, at least on your own, to fix your iPhone proximity sensor not working. As you presumably know, you actually can’t disable or pause the proximity sensor on your iPhone. The best you could do is to ensure it remains in a pristine condition or fix it at your earliest convenience when it doesn’t work. At this point, we recommend you replace the proximity sensor. If you’re still within your Apple warranty period, we recommend sending your phone to Apple or visiting the official store near you.
