Meta description: Learn how to test your phone’s proximity sensor with UK-tested methods. Real user insights and step-by-step checks to ensure it works properly.
Snippet (first 60 words): Wondering if your proximity sensor is working correctly? Users across London, Manchester, Birmingham, and Glasgow on EE, O2, Vodafone, and Three frequently encounter sensor issues. Based on real-world testing and experience with AvNexo tools, here’s a complete guide to testing your phone’s proximity sensor effectively, diagnosing faults, and fixing common problems.
A proximity sensor detects when your face or ear is near the phone during a call, turning off the screen to prevent accidental touches. If it malfunctions, users in cities like Leeds, Cardiff, and Edinburgh report screens staying on, random touches, or speakerphone toggling unintentionally.
This is the simplest method. Make a call and cover the top front sensor area with your hand or finger. Observe if the screen turns off immediately.
Most Android phones have hidden test menus that allow direct sensor testing.
Steps:
Dial `*#0*#` (Samsung) → Select “Sensor” → Check proximity readings
Other manufacturers may require checking settings or entering a diagnostic code.
UK users’ experience: In Leeds and Edinburgh, this method revealed sensors blocked by residual adhesive from previous screen protectors.
Apps on Google Play or the App Store allow live readings from your proximity sensor.
Steps:
Install a reputable sensor test app → Follow the on-screen instructions → Cover and uncover the sensor → Observe readings
Users from Cardiff and Glasgow found this method useful to distinguish between software and hardware issues, particularly after system updates.
Booting into Safe Mode disables third-party apps, helping identify if an app is interfering with the sensor.
Steps:
Power off → Hold Power button → Long-press “Power Off” → Choose Safe Mode → Make a test call
Many Vodafone and Three users in Manchester confirmed this method successfully revealed app conflicts affecting the proximity sensor.
Examine the sensor area for dust, dirt, fingerprints, or screen protector misalignment. A thin layer of residue can completely block infrared sensors.
Pro tip: Users in London and Birmingham report dramatic improvements after cleaning the sensor with a dry microfibre cloth.
Restarting the phone can resolve temporary software conflicts affecting the sensor. Users in Leeds and Edinburgh often notice intermittent problems disappear after a reboot.
If the sensor works in some apps but not others, the issue is likely software-related. For example, WhatsApp calls might trigger different behaviour than the native phone app, as observed by users in Glasgow and Cardiff.
If all tests indicate software is the culprit and cleaning didn’t help, a full factory reset can remove corrupted system data affecting the sensor. Backup your data first. London and Manchester users confirmed this method restored sensor functionality in rare cases.
Testing your phone’s proximity sensor is straightforward if you follow systematic steps. From simple manual tests during calls to diagnostic menus and third-party apps, UK users across London, Manchester, Birmingham, Glasgow, Edinburgh, and Cardiff have successfully identified and fixed sensor problems.
Most failures are caused by dirt, screen protectors, or minor software issues. Hardware faults are rarer but should be considered if the sensor fails consistently despite cleaning and testing. Following these methods ensures accurate assessment and helps prevent misdiagnosing the issue.
