Email and Messaging

One of the built-in features of iOS can easily block specific phone numbers on the iPhone. When a phone number is blocked, it prevents incoming voice calls, messages and FaceTime from getting through. Mail senders can also be blocked, with the Mail app recognizing blocked email addresses and ignoring them.

For some time, iOS has made it possible to hide alerts on a Messages thread. This can be useful when a slew of text messages comes in, and you need the iPhone to remain quiet. Similar to hide alerts, Apple has added a mute function to email threads on the iPhone, iPad and iPod touch.

Whether you need specific symbols for a technical paper or are simply looking to add some flavor to your social media posts, the iPhone keyboard doesn't have a very extensive library of symbols. You can find a few extra symbols by long pressing on certain keys like the '$' which will reveal a few other currency symbols, and you can find some in the emoji library like the trademark and copyright symbols, but they aren't really ideal (they don't appear as superscripts).
