Troubleshooting Guide: Mobile Phone Screen Not Turning Off After Call
Having your mobile phone screen stay on after a call can be frustrating and inconvenient. Not only does it drain your battery unnecessarily, but it can also lead to accidental touches and unintended actions on your device. In this troubleshooting guide, we will explore some possible reasons why your mobile phone screen is not turning off after a call and provide solutions to fix the issue.
1. Check Screen Timeout Settings
The first thing to check is your screen timeout settings. Screen timeout determines how long your phone’s screen stays on before it automatically turns off. To adjust this setting, follow these steps:
- Go to the “Settings” menu on your phone.
- Select “Display” or “Display & Brightness”, depending on your device.
- Look for the “Screen timeout” or “Auto-lock” option.
- Choose a shorter duration, such as 30 seconds or 1 minute.
By setting a shorter screen timeout, your phone’s screen will turn off more quickly after a call.
2. Disable Proximity Sensor Calibration
Most modern smartphones have a proximity sensor that detects when the phone is held up to your ear during a call. This sensor is responsible for turning off the screen to prevent accidental touches. However, if the proximity sensor is not calibrated correctly, it may not work as intended. To disable proximity sensor calibration, follow these steps:
- Open the Phone app on your device.
- Dial the following code: *#77692#
- A calibration menu will appear on the screen.
- Select the option to disable proximity sensor calibration.
Disabling proximity sensor calibration may resolve the issue if the sensor is malfunctioning or not working properly.
3. Update or Reinstall Phone App
In some cases, the issue may be related to the phone app itself. Outdated or corrupted app files can cause various issues, including the screen not turning off after a call. To update or reinstall the phone app, follow these steps:
- Open the app store on your device (e.g., Google Play Store or Apple App Store).
- Search for the phone app.
- If an update is available, select the option to update the app.
- If no update is available or updating doesn’t resolve the issue, uninstall the app and reinstall it.
Updating or reinstalling the phone app can often fix software-related problems that may be causing the screen to stay on after a call.
Conclusion
Having your mobile phone screen not turning off after a call can be frustrating, but fortunately, there are several troubleshooting steps you can take to resolve the issue. Start by checking your screen timeout settings and adjusting them to a shorter duration. If that doesn’t work, try disabling proximity sensor calibration to rule out any sensor-related problems. Finally, consider updating or reinstalling the phone app to address any software-related issues.
If none of these solutions work, it may be necessary to seek assistance from your device manufacturer or contact customer support. They will be able to provide further guidance and help resolve the issue.
