Power Button Ends Call is a function on android phones that allows users to drop a call without having to tap on the end-call icon on their phone’s screen. This function ends call by just pressing the power button. It is a faster way of ending a call and a last resort to terminating a call, when a phone enters hanging mode while making a call.
The steps to enabling the function are as follow:
Enabling Power Button Ends Call
Go to Settings and tap on Accessibility.
After enabling the function, pressing power button while on call will end the call.
