Meta description: Proximity sensor failing during calls? Here’s a UK-focused guide with real user experiences, causes, and practical fixes that actually work.
Snippet (first 60 words): If your phone screen stays on or behaves oddly during calls, it’s likely a proximity sensor problem. From London to Manchester, Glasgow to Edinburgh, UK users on EE, O2, Vodafone, and Three report similar issues. Based on hands-on testing, including devices integrated with AvNexo workflows, here’s why proximity sensors fail and how to fix them reliably.
The proximity sensor is deceptively simple but crucial. It detects when your face is near the phone during a call and turns the screen off to prevent accidental touches. Users in cities like Birmingham and Bristol notice problems immediately: the screen stays on, touches register unexpectedly, and speakerphone toggles trigger by accident.
In my hands-on testing, I’ve found that the same phone can behave perfectly in Cardiff but fail repeatedly in rainy Manchester mornings. Environmental conditions, software conflicts, and minor hardware issues all play a role.
This is by far the most common cause. Users commuting on the London Underground or cycling through Glasgow consistently report screen issues due to grime build-up. Pocket lint, makeup residue, or leftover sunscreen can partially block the sensor.
Real example: A user in Leeds using O2 noticed that their sensor worked fine in the morning but failed during evening commutes. Cleaning the sensor resolved the problem instantly.
Fix: Use a dry microfibre cloth → gently wipe the sensor area → remove any protective film or dust particles → retest during a call.
Cheap or poorly aligned screen protectors can interfere with infrared sensors. A Birmingham EE user replaced his screen protector multiple times before realising it was too thick for the under-display sensor.
Fix: Use a UK-made, sensor-compatible protector → ensure proper alignment → clean underneath before installation.
The UK’s climate is rarely dry. Users in Edinburgh, Aberdeen, and Cardiff often see sensor glitches on humid or rainy days. Sweat, light drizzle, or condensation from sudden temperature changes can block the sensor momentarily.
Human insight: During testing in Manchester, even a brief 5-minute exposure to rain caused the proximity sensor to behave erratically on an iPhone and a Samsung device simultaneously.
Fix: Dry hands → Wipe the screen → Test calls in a dry environment.
Sometimes, updates push changes that interfere with sensor calibration. Users on Vodafone and Three frequently report call issues immediately following system updates.
Steps to check:
Example: An EE user in London found that after an Android update, proximity sensor issues occurred only in WhatsApp calls. Clearing app cache resolved the problem.
Some failures are physical. Drops, screen replacements, or manufacturing defects can misalign or damage the sensor. Glasgow and Leeds users reported faulty sensors after third-party screen replacements, even when the display looked perfect.
Signs of hardware failure:
In these cases, repair or replacement is the only solution.
Dry microfibre cloths work best. Avoid alcohol wipes directly on the sensor, as residue can create a thin film.
Make sure your protector is compatible with the proximity sensor. Align it carefully and remove any trapped dust.
Dry your hands, wipe the screen, and test in a dry indoor location. Humidity and cold UK weather often exacerbate sensor glitches.
Restarting can reset minor conflicts. Safe Mode disables third-party apps that may interfere with sensor function.
Settings → Apps → Show system apps → Phone or Call app → Storage → Clear Cache. Users in Cardiff and Sheffield report improvement after this step.
Ensure the device has the latest firmware. Updates often include fixes for sensor calibration, especially on devices from Samsung, Google, and Xiaomi.
If all else fails, a full factory reset can resolve software-related conflicts. Backup your data first. Real UK users from London and Manchester only resorted to this after trying all other steps.
If the sensor fails even after cleaning, removing protectors, drying hands, restarting, clearing cache, and updating software, it’s likely a hardware issue. Seek repair from a trusted UK service centre — ideally one using OEM parts — to avoid repeated failures.
Users from Edinburgh and Glasgow found that professional repair solved the problem permanently after months of intermittent failures. Trying cheap fixes repeatedly can worsen sensor alignment or damage the display.
Proximity sensor failures during calls are frustrating but solvable. Most issues in the UK arise from dirt, moisture, protectors, or minor software conflicts. Real hardware failure is less common but can’t be ignored — especially after drops or third-party repairs.
Following the practical steps above — cleaning, drying, testing in safe mode, and updating software — resolves the majority of problems. For persistent issues, professional repair is necessary. Devices integrated with AvNexo tools benefit from faster diagnostics and tracking of sensor behaviour, making it easier to spot when a hardware replacement is needed.
