MOUNTAIN VIEW, CALIF.: Nougat, Google’s latest update of its Android smartphone software, isn’t particularly flashy; you might not even notice what’s different about it at first. But it offers a number of practical time-saving features, plus a few that could save money — and perhaps even your life.

You’ll be able to switch between apps more easily and do more without opening apps at all. New settings also let you block apps from eating up cellular data in the background.

Nougat is starting to appear on phones, including new ones expected from Google next week.

Some of these features may seem familiar because individual manufacturers such as Samsung and LG have built them on their own. But now they are officially part of Android, which means they should work with a greater range of apps and phones.

To switch apps in the past, you had to tap a small square at the bottom and scroll through your open apps. Now, just double tap that square to go directly to your most recently used app. Keep double tapping to toggle between them — for example, if you want to switch back and forth between email and map.

Nougat will let you reply to messages directly from a notification; for chats, you can also see recent sent and received messages from both sides, not just the most recent incoming note. And when apps such as Gmail group multiple notifications into one, just slide down the notification center from the top to see more on each item rather than an unhelpful “5 new messages.”

A data-saver feature blocks apps from using cellular data while running in the background. Google says that even if an app is active, images and other data-hungry elements might not load until you tap them. You can still choose to have specific apps override that — for example, if you absolutely must have your Facebook app check for updates around the clock.

For emergency purposes, you can enter your name, blood type, allergies, emergency contacts and other crucial data in the settings. Emergency personnel can access the information by tapping “emergency” from the lock screen; they don’t need your passcode.

To control what notifications you receive, just tap and hold a notification. You can choose to block notifications from that app or silence them as they come in. Or prioritize them by having notifications still appear when you set “Do Not Disturb” to “Priority only.” (This option still requires going to the settings, but it’s just one tap away from the notification.)

Ready for the update? You’re in luck if you have one of Google’s recent Nexus phones, as Nougat is already available. LG’s new V20 phone ships with Nougat, starting this week in South Korea, while new phones expected from Google next week should also come with it. As is typical in the Android world, some phones might not have all of the new features, and some features might work differently.

Everyone else should expect to wait awhile. Android updates have to get tweaked and approved by both phone manufacturers and wireless carriers.
