. 1 Have your device doze
One of Marshmallow's headlines is Doze. It saves battery life when your phone or tablet is not being used, reduces background activity, and less frequently scans for new notifications. Once you resume the device, it will come alive again. Android 6.0 automatically turns on Doze if it detects that your phone or tablet is not being used. There are no setting options: Make sure you do something useful with the extra battery life.
. 2 Review app permissions
App permissions have changed to Marshmallow and are more (whisper softly) iOS-like. Instead of asking for permissions in advance, apps ask for them as needed: permission to use the camera when you take a picture, permission to use your location when you open a map, and so on. It also means that you can authorize some permissions and not others within the same app (for example, Facebook could have access to your location, but not your contacts). Go to Settings, select Apps, then tap the gear icon, then tap App permissions to turn it on or off.
. 3 Embrace USB Type-C
This is not a tip you can use on a device that you have upgraded to Marshmallow, but you will see it on new Android 6.0 devices (such as Nexus 5X and Nexus 6P). The new operating system supports USB Type-C, the latest USB standard that supports faster data transfers, faster recharging, reversible cables, and multitasking (so you can output videos and recharge your device at the same time). USB Type-C has also appeared on laptops, including the new Apple MacBook and the latest Chromebook Pixel from Google.
. 4 Tap on Google Now … on Tap
Android's digital assistant Google Now has gained some extra powers with the release of Marshmallow – especially the ability to see what's on screen and the context of what you see , Long press the Home button to turn on Google Now. If you repeat an action in the future, you will receive information relevant to the app and the information displayed. For example, a movie could be linked to Wikipedia or IMDB entries, or a local business might link to directions and its official website.
. 5 Ask Questions About Your Apps
Google Now on Tap also works with your voice if you want to test the new contextual features. Start Google Now as usual with a long press of the Home button, say your request, and assume that the virtual assistant knows what's on the screen: "Who's that?", For example, if you have a song on spotify or "when does it show?" when someone mentions a movie in an email. As more and more apps adopt the Google Now on Tap standard, it should be able to get smarter.
. 6 Choose Your Own Quick Settings
The Quick Settings area appears in Android when you drag down from the top of the screen with two fingers. If you press and hold the gear icon above the window in the latest version, you can enable a System UI tuner entry in the device's App Settings. If you follow this menu item, you can change which tiles will be displayed on the Quick Settings screen and move them. It is also possible to hide certain icons (eg Bluetooth or Airplane mode) via the status bar.
. 7 Show the battery level as a percentage
This is another entry in the hidden System UI tuner menu. If you have not activated it yet, we refer back to the previous tip (long press the gear icon in the Quick Settings section). Third-party modding programs have allowed you to see the battery level as a percentage in the status bar for some time, but now it's a native feature – go to System UI Tuner by Settings and then tap Show Embedded Battery Percentage. If you want to know exactly how much juice your device has at a glance, this is the way to go.
. 8 Back up your app settings
This is more of a tip for app developers than for app users, but everyone should be aware of it. Android Marshmallow gives apps the ability to back up data and settings to your Google Drive account for free. In other words, if you sign in to a new Android device and find all of your contacts and emails, all of your apps will be in the same state they were when they left you, provided the app developers did decided to make use of the feature.
. 9 Quick access to apps and contacts
Android's share menu has long been one of its strengths – the way you can send almost anything from one app to another with just a few clicks – and it is even smarter in marshmallow. Whenever you tap Share in an app, the mobile operating system calls the contacts and apps you use most often. If you're a frequent tweeter, Twitter is likely to be the most frequently viewed when you share a link. All other apps and contacts will also be displayed, but your favorites will be moved to the top.
10th Changing Default Apps
Like a desktop OS (and unlike iOS), Android lets you set default apps-apps that are automatically selected to open web sites, pictures, text messages, and more. Marshmallow has made things a little easier: If you tap Apps in Settings under Apps, then tap the gear icon and select Standard apps on the following screen, you can edit those links. For example, tap "Browser" and you can select anything other than "Chrome" every time you try to view a webpage.
. 11 Seamlessly Access the Web
This is another interesting feature for app developers, but you should notice the benefits of using Android Marshmallow – Apps can now use Chrome Custom Tabs to view web pages without having to use the app leave (in Twitter or Facebook for example). That means all the benefits of Chrome, including your synced passwords and existing logins, without having to jump to Chrome and back again. Developers can also customize the toolbar colors and action buttons of these custom tabs for a seamless and fast user experience.
12th See how much memory your device has left
Android has gradually given users access to some of the hidden features behind the scenes. New in Marshmallow is a memory manager that lets you see which apps use your device's power of thought and crash it. In the Settings app, tap "Memory" and you can break down the statistics for the last three, six, twelve or 24 hours. If you choose the storage used by apps, you can see the worst contributors to memory usage.
. 13 Easily select text
If you spend a lot of time texting on your Android device, you'll love this improvement – especially on smaller screens or with limited dexterity. If you press and hold a word on the screen, it will be marked as normal, but then as you move around with your fingers, words are selected rather than individual characters (if you need a precise selection, you can drag one of the two blue handles). In addition, the menu bar has been re-aligned with Cut, Copy and Split so that it now floats close to the text.
fourteenth Swipe Right for Voice Access
The Eagle has noticed that the shortcut icon in the lower-left corner of the lock screen now activates a voice search instead of connecting to the dialer app – apparently we are now performing all web searches instead of calling each other. Swipe up and to the right to access Google Voice Search and perform an online query (such as the age of the Prime Minister). Any attempt to conduct a personal search on Google (such as "my flights" or "my emails") will not return a result if you have not previously completed the Locked Screen Security.
15th Manage volume in one place
Android 5.0 Lollipopmade Volume control unnecessarily confusing, so Android Marshmallow tries to fix some of the damage. When you press the volume key, a simple slider bar appears on the screen – tap the slider down arrow and you can change media, system, and alarm volumes all from the same pop-up window. If you need more control over the volume, go to the Sound & Notification screen in App Settings (options like default ringtones and vibration can also be configured here).
sixteenth Put a "do not disturb" sign
Google also changed the "do not disturb" setting to make it (theoretically) easier to use. In the Tones and Alerts screen under Settings, you can invoke the Do Not Disturb option and list contacts and events that can overcome any silence in Priority mode. To select the current mode, open the Quick Settings panel and tap Do Not Disturb – the options are Priority Only (only alerts from certain apps and people emit a tone), Alarms only (only alarms emit a sound), or Total Silence  17. First to Your Favorite Apps
New in the Google Now Launcher (based on the Android Marshmallow) is an app drawer in which your most used apps first when you're on the phone – you can see the new feature as soon as you tap the All Apps button (usually in the middle of the Home screen). At the top of the page is a search box where you can scroll by searching for apps page by page. Searching for. The scroll bar on the right can also be used to quickly browse installed applications.
18th Unlock Your Device With One Finger
Samsung and other manufacturers have been integrating fingerprint sensors into Android hardware for some time, but Android Marshmallow is the first time the feature is natively supported by the operating system (so you should see a lot more). Phones and tablets that will carry sensors in the future. Google's Nexus 5X and Nexus 6P are two of the first mobile phones to feature this sensor technology. You can use anything to unlock your device or buy apps and games in the Google Play Store.
19th Do not Worry About Links Between Apps
Our latest developer tip focuses on links between apps – and we'll mention it again to let you know why your Android Marshmallow experience is more seamless and straightforward than In front. In previous versions of Android, when you tapped a website URL, a link to a tweet, or something similar, a dialog box appeared asking you which app to open it with. In Marshmallow, these links can be predefined to automatically open in their default apps, so no extra screen is displayed.
20th Find Your Files
Android finally has a file manager, even if it's hidden in the depths of the operating system. If you go to the Settings app and then select "Storage & USB," you'll be able to see how much space is left on your device. If you then scroll down and tap Browse, you can browse the various folders on your smartphone and tablet. There are not many features here, but it's a start (and if you need an advanced file manager, many third-party options are available in the Play Store.)
21. Download it on Android Pay
This is a bit of a scam, because it is now only available in the US and it works with Android 4.4 and higher (not just Marshmallow), but we're going to mention it anyway because it's a big new Google product. Similar to Apple Pay, Android Pay allows you to buy goods with a swipe on your NFC-enabled smartphone wherever your service is supported – it's not the first time that Google has caught on a mobile payment service with heavy traction.
