A common complaint with the Samsung Galaxy S4 is that the screen might turn off during a call. This can create a problem when you are using the dial pad to execute options on a phone menu system or dialing into voice mail.
The screen may shut off every time you attempt to use the screen while on a call. The reason is that the Galaxy S4 has a proximity sensor that detects when you put the device up to your ear. Sometimes that sensor detects your hand and shuts the screen off during a call.
You can try to avoid getting your hand near the proximity sensor, but it’s sometimes difficult. Fortunately, there is a way to disable the sensor completely. Just follow these steps:
- Open the “Phone” app.
- Press the “Menu” button.
- Select “Settings“.
- Deselect the “Turn off screen during calls” option.
One thing to note that, if this option is not selected, the screen will stay on all throughout the call. This will have a slight effect on battery life, and you might accidentally trigger options when you place the phone up to your ear.
