Reducing animation Scale:
You can make your Android device feel snappier by reducing or turning off some of animations. You’ll need to enable Developer options in order to do this. Go to Settings > About phone and scroll down to the System section to look for Build number. Tap on it several times and you should see a message about being a developer.
You can now go back to the previous menu and you should see Developer options listed under System. Head in there and scroll down to find Window animation scale, Transition animation scale, and Animator duration scale as shown above. Tap each in turn and set it to .5x or off. Pick an option and find out what suits you, if you don’t like just go back in and change the values again.
Unlock a hidden "Reader Mode" in Chrome:
This button makes it easier to read articles on a smaller screen. In Chrome, type "Chrome://flags" in the URL bar. Then in the main Menu, select "Find in page" and type "Reader Mode Toolbar icon." Once you find it, enable the feature.
Then force-stop Chrome (Settings > Apps > Chrome) and relaunch the app. Now, on select websites, you'll see an "A" icon near the browser bar.
Priority mode is probably one of the most underrated and underused features on the entire operating system.
In short, it allows you to put your phone into quiet mode, but still allow some “noises” to get through. This could be calls, texts, or WhatsApps from specific contacts, notifications from certain apps, or important alerts such as alarms.
To set it up, go to Settings > Sound & Notification > Do not disturb, then select the options that you require.
Hidden Android game:
Go to Settings > System > About Phone (or Software info), and when you see the words “Android version,” tap on it multiple times and you’ll see a logo for Nougat or Marshmallow. Tap a few times again and now press and hold on the screen. A secret minigame will appear.
Tap the triangle to start. See how long you can keep the Android character alive by tapping the screen to jump, and without hitting any obstacles.
If you have kids using your phone regularly, this is a great way to make sure they don’t accident run up huge bills or set their eyes on content that is age-inappropriate.
Firstly, you’ll need to enable the feature (oddly, it is turned off by default). Do that by going to Settings > Security and scrolling down to Screen pinning.
To pin a screen, open the app, press the Overview button (the square) and then the pin icon.
You can choose to PIN-protect the pinned screen, if you so wish.
