Never End a Call By Mistake Again

It happens to everyone; you’re talking on the phone, and you accidentally press the Side button on your iPhone. All of a sudden, you hung up the call, and you had no idea what had happened.
This has been an annoying feature for a few years, but Apple finally made it so we can disable it like this:
- Open the Settings app.
- Scroll down and tap on Accessibility.
- Scroll down again and select Touch.
- Go down one more time and enable Prevent Lock to End Call.
