If you’re wondering why does my phone screen turn off during a call, it is because the proximity sensor turns the screen off when the top half of the phone is covered by something, such as your face or cheek.
This happens due to a technology called “proximity sensor”, which detects if there is an obstacle near the front camera and turns the screen off in that case.
The proximity sensor is found in different parts of phones and it can be located in the front side or near the earpiece, in this case during a call. However, there are some smartphones that also have these sensors on their backside to turn off the display when you put them down, for example.
There is an app called the NoBounds which will let you use your proximity sensor to set some shortcuts.
But, if your phone doesn’t have a proximity sensor, there are apps in Google Play Store for this usage too. For example, Screen Off and Lock or Proximity Sensor Settings work just fine.
These apps are specially designed for devices that are unable to use their proximity sensor due to some hardware defect.
Also, if you’re too fond of using your phone during a call or find yourself constantly pocket-dialing or accidentally hanging up on calls, it might be worth getting a case with an extra flap over the screen. This also ensures that your phone is locked during calls, so you don’t accidentally hang up or pocket-dial.
As for using your proximity sensor as a shortcut to apps, the use of these is usually discouraged by smartphone manufacturers since they can drain battery and cause excessive heating. But if you want to get even more out of your device, try downloading some tricks and tips apps like No Signal Flashlight or NoPhone Signal.
If you are still wondering why does my phone screen turns off during a call, it is due to the proximity sensor. Handy apps for your phone if it doesn’t have a proximity sensor are No Signal Flashlight or NoPhone Signal.
Don’t use your smartphone frequently during calls since this can cause pocket-dialing or accidentally hanging up on calls. If you still want to use your phone during a call and do not want to get a case with an extra flap, try downloading the NoBounds app for your smartphone.
