The iPhone has a hidden feature that allows you to quickly redial the last phone number that you called. Rather than thumbing through your contact list to find your friend’s number again, you can immediately bring it up by using the manual dialer.

All you need to do is open the Phone app on your iPhone, open the manual dialer, and tap the green call button without entering anything. The first time you tap the call button, the last number that you called or dialed will be automatically pasted into the number entry. If you press the call button again, you’ll call that number. 

All in all, it’s three quick taps (open the dialer, tap the call button, tap it again) versus several minutes of contact list scrolling and number-selecting. It’s much quicker, to say the least, especially if your contacts list is especially long. Just remember to take a moment to check the number before you redial, in case you’ve been making a lot of different calls.

While we’re on the subject of re-dialing, if you use Siri on your phone, you can also quickly redial a number with a voice command. Just activate Siri and say “redial that last number” to immediately call the last number that you dialed. Or, if you want to quickly hop back onto a number that called you, you can say “return my last call.”

Notification history has been around on Android phones for years now, but the method to access the setting varies by which smartphone you’re using. Some phones, like the Google Pixel, use a stock version of Android, while others, like OnePlus and Samsung, use their own interface on top of Android. Here’s how to find the feature, irrespective of which version of Android your phone is running:

1. Open the Settings app on your Android phone.
2. Tap Notifications.
3. Tap Advanced settings or More settings.
4. Tap Notification history.
5. Turn on the toggle on the next page.

On a Google Pixel phone, you’ll find Notification history inside the main Notifications settings menu. If you can’t see the option on your Android phone, use the search bar in the Settings app to search for Notification history. Tap on the option and turn on the toggle next to it.

Depending on who you ask, mowing the lawn is either an enjoyable weekend routine or a seemingly never-ending chore. For anyone in the latter camp, Husqvarna’s Automower does almost everything for you — all you have to do is set it up and leave it to run. Well, not quite — you’ll have to install a boundary wire around your yard first so that your mower doesn’t pay an unsolicited visit to the neighbor’s house, but once it’s set up, it’s pretty hassle-free to operate.

Using the Automower Connect app, you can check in on how your mower is doing, find exactly where it is, and see how far it’s progressed through the mowing cycle. Alternatively, its status can also be checked through Google Assistant or Amazon Alexa. An alarm system and PIN code locking system help deter thieves, and you’d certainly hope so given the price, as it retails for $2,499.99 on Amazon, but is sometimes discounted to $1,999.99.
