6 things you don’t have to root Android to do any more

For years, Android enthusiasts have been rooting their devices to do things that Android doesn’t allow by default. Google has added many features that once required root to Android, eliminating many of the reasons for rooting. Some of these features were added in Android 4.1 Jelly Bean, some were added in Android 4.0 Ice Cream Sandwich, and some were added in earlier releases.
Without root access, you can now:
1. Take Screenshots: To take a screenshot, press the Volume Down and Power keys at the same time.
2. Disable Preinstalled Apps: You can now “freeze” (or disable) preinstalled applications on your Android. This is particularly useful for bloatware that carriers or manufacturers may include – of course, it’s possible some manufacturers may disable this feature on their devices. To disable a preinstalled application, open Android’s Settings screen, select Apps, and flick over to the All category. Tap the app you want to disable in the list. If you can’t uninstall the app, you’ll see a Disable button where the Uninstall button would be. Tap the button to disable the app. The Disable button may not be available for some essential packages that are part of the Android OS, but you can disable default apps like the Calendar, Gallery, and Clock. You can even disable Android’s built-in keyboard.
3. Revoke Notification Permissions: While Android still doesn’t allow fine-grained control of all the permissions an app requests without root access, you can revoke the notification permission from an app. This is ideal for apps that abuse notifications by showing ads or apps that just show too many permissions. Go into the Settings screen, select Apps, and tap the app you want to disable notifications for. Uncheck the Show notifications box and the app won’t be able to display notifications anymore.
4. Restrict Cellular Data: With Android’s built-in tools, you can restrict specific apps from using the cellular data connection in the background. It’s not quite a firewall that blocks network access for specific apps, but it’s still useful. To take advantage of this feature, go into your Settings screen and select Data usage. In addition to setting data limits, viewing charts, and disabling mobile data entirely, you can tap a specific app and check the Restrict mobile data check box to prevent the app from using mobile data in the background. The app can still use data if you open it, and can still use data on Wi-Fi networks – but it won’t be able to use the cellular data connection in the background. If you’re using a Wi-Fi network that’s actually a mobile hotspot, you can tap the menu button, select Mobile hotspots, and tell Android whether a specific Wi-Fi network should be treated as a mobile network. Android will treat the selected networks as mobile data networks instead of Wi-Fi networks.
5. Encrypt Device Storage: Android includes built-in encryption support, allowing you to encrypt your smartphone or tablet’s entire storage. When you power it on, you’ll have to enter its encryption password – if you forget this password, you’ll have to perform a factory reset and lose all your data. If your device is stolen, the thief will need your credentials to decrypt it and access your data (assuming it’s powered off). To encrypt your Android smartphone or tablet, go into it Settings screen, tap Security, and tap Encrypt tablet or Encrypt phone. The process will take some time.
6. Connect to VPNs: If you want to connect your Android to a virtual private network – say, your work VPN – you don’t need to root it and install a VPN client anymore. To connect your Android to a VPN, go into its Settings screen, tap More under Wireless & Networks, and tap VPN. You’ll be able to add and edit multiple VPN profiles.
