iOS 11 has a hidden feature that automatically answers a phone call for you. This can be a cellular call or a VoIP call from apps like WhatsApp or Skype. If you’ve been around the internet for a long time, you might remember Nokia phones with a similar feature.
It’s meant to be an Accessibility feature but it can be used for all sorts of reasons. If you’re the kind of person who always needs to pick up your phone when you’re at work, or when you’re in the car, you can enable this feature. Alternatively, you can turn this on when you have open office hours at work.
How to Enable Auto Answer for Calls
Step 1: Open the Settings app.
Step 6: Select the duration after which the call will be answered automatically. By default, it’s at 3 seconds. But you can select anything between 0 and 60 seconds.
