Introduction
Having a mobile phone screen go blank during calls can be frustrating and inconvenient. It can disrupt important conversations and make it difficult to access features or end the call. In this troubleshooting guide, we will explore some common reasons why this issue occurs and provide potential solutions to resolve it.
Possible Causes
There are several reasons why your mobile phone screen may go blank during calls. Some of the common causes include:
- Proximity sensor issue
- Software glitch
- Screen protector interference
- Hardware problem
Troubleshooting Steps
1. Check Proximity Sensor
The proximity sensor is responsible for detecting when the phone is held up to your ear during a call. If it malfunctions, it may cause the screen to go blank. To check if the proximity sensor is the issue, follow these steps:
- Make sure your phone is clean and free from any dirt or debris that could be obstructing the sensor.
- Restart your phone and try making a call again.
- If the problem persists, check your phone’s settings to ensure the proximity sensor is enabled. You can usually find this option under the “Display” or “Call” settings.
- If the sensor is enabled and the issue continues, you may need to contact your phone manufacturer or service provider for further assistance.
2. Update Software
Software glitches can sometimes cause the screen to go blank during calls. Updating your phone’s software to the latest version can often resolve such issues. Here’s how to update your software:
- Go to your phone’s settings.
- Select “Software Update” or “System Update”.
- Check for any available updates and follow the on-screen instructions to install them.
- Once the update is complete, restart your phone and test if the issue persists.
3. Remove Screen Protector
If you are using a screen protector, it may be interfering with the proximity sensor, causing the screen to go blank during calls. Try removing the screen protector and see if the issue is resolved. If the problem persists, you can try using a different screen protector or contact your phone manufacturer for further assistance.
4. Hardware Problem
If none of the above steps resolve the issue, it is possible that there is a hardware problem with your phone. In such cases, it is recommended to contact your phone manufacturer or service provider for professional assistance. They will be able to diagnose the issue and provide appropriate solutions or repairs.

However, by following the troubleshooting steps outlined in this guide, you can identify and resolve common causes of this issue. Remember to check the proximity sensor, update your software, remove any screen protectors, and seek professional help if necessary.
