I think a lot of non tech people would REALLY benefit from a setting to "confirm before dialing" in ios.
For example, touching ANYTHING in the phone app will immediately dial that number.
That leads to real problems with inexperienced users, who then get the mindset that they're not good with tech.
To be clear - the blame here is 100% on apple.
Most people I know have butt dialed. I consider myself highly aware of my phone, yet have accidentally called back spam callers. yikes!
