Mobile Screen Turning Off During Calls: Troubleshooting and Solutions

Have you ever experienced frustration when your mobile screen turns off automatically whenever you receive or make a call? This article provides a comprehensive guide to help you diagnose and fix this issue. By following the basic steps and troubleshooting tips, you can ensure a smooth call experience.

Basic Steps to Troubleshoot

1. Restart your phone

When your mobile screen turns off unexpectedly, it might be a temporary glitch that can be resolved by restarting your device. Try powering off your phone and turning it back on. This can help clear any temporary software issues that might be causing the problem.

Possible Causes and Solutions

1. Proximity Sensor Issue

Many smartphones have a proximity sensor near the earpiece that detects when the phone is held to your ear. Its primary function is to turn off the screen to prevent accidental touches during a call. If this sensor is malfunctioning, it might incorrectly detect that the phone is near your face and turn off the screen.

If this is the issue, the problem might be due to a sensor that is dirty or obstructed.

Solution:

Check if there’s anything covering the proximity sensor, such as a screen protector or dirt. Ensure that the device is not covered in any way that might block the sensor. Wipe the sensor area gently with a soft cloth to remove any dirt or debris.

2. Screen Timeout Setting

Another common issue is a screen timeout setting that is too short. This setting determines how long the screen stays on before it automatically turns off when not in use.

Solution:

Adjust the screen timeout setting to a longer duration if you find that the screen turns off too quickly during calls. This setting can typically be found in the Display or Screen settings of your phone.

3. Proximity Sensor Calibration

Proximity sensors might also need recalibration after software updates or if the phone has been dropped. Recalibration can help improve the sensor's accuracy.

Solution:

To recalibrate the proximity sensor, locate the option in the phone’s settings under ‘Accessibility’ or ‘Display’. Follow the on-screen instructions to calibrate the sensor.

When Professional Help is Needed

If these solutions don’t resolve the issue, it could potentially be a hardware problem with the proximity sensor itself or a software glitch that might require further diagnosis by a technician. In these cases, it is advisable to consult a professional to ensure that the sensor is functioning correctly and to rule out any potential hardware issues.

By following the basic troubleshooting steps and identifying the cause of the issue, you can enjoy seamless calls without interruptions caused by your screen turning off. If you need further assistance, don’t hesitate to reach out to a professional for help.
