Until now, pressing on your phone side button to Lock Screen would stop the phone call you would be in. Convenient for some of us but for some others., like me, it isn't great. Never accidentally pressed a button with your face during a phone call ? Well we got you covered here.
Go to Settings
2 fingers swap down to reveal search bar
Type 'Lock Screen' and search
Click on 'Prevent Lock to End Call'
Scroll down and look for that option and activate it.
If you want to return to the original setting proceed the same way and switch the option off.
