Why does my screen go black during a call?

There can be several reasons why your screen goes black during a call. It could be due to a software glitch, hardware issue, or even a setting on your device. Let’s explore some possible causes and solutions:

1. Proximity sensor: Most smartphones have a proximity sensor located near the earpiece. This sensor detects when your phone is held up to your ear during a call and turns off the screen to prevent accidental touches. However, if the proximity sensor is not functioning properly, it may cause the screen to stay black even after you move the phone away from your ear. To check if this is the issue, try making a call and see if the screen comes back on when you move the phone away from your ear. If not, you may need to calibrate or replace the proximity sensor.

2. Software glitch: Sometimes, a bug in the operating system can cause the screen to go black during calls. This can happen if the phone’s software is not up to date or if there are compatibility issues with certain apps. To fix this, try updating your Android system to the latest version. Open the Settings app on your device, scroll down to “System” or “About phone,” and look for a “Software update” or “System update” option. If an update is available, download and install it. This should resolve any software-related issues.

3. Battery-saving mode: Some Android devices have a battery-saving feature that automatically turns off certain functions, including the screen, to conserve power. If your phone is in battery-saving mode, it may cause the screen to go black during calls. To check if this is the case, go to the Settings app, look for a “Battery” or “Power” section, and disable the battery-saving mode if it’s enabled.
