Press the Call Button on Your Smartphone to Redial Last Call

Here’s a tip that a lot of folks forget about now that we use smartphones more than landlines. Your phone keeps the last number dialed available so you can easily call them back. In both iOS and Android, you can press the call button in the phone app for a quick call-back feature. This is great in dead spots when calls drop, when you get a busy signal or when you are on a conference call.
