ANDROID SECRET FUNCTIONS ( YOU MAY BE AMAZED )

Hey guys , today i am writing about some secret functions of android .
There are bunch of secret function which you would be unaware so, lets check them !!!!!!!

 1-  EASTER EGG

Each version of android has a special little hidden interactive  animation to show off the version of android version you are currently running.
To find this cool animation you have to follow simple steps

3- IMPROVE BATTERY LIFE AND PERFORMANCE

4- INCREASE PHONE SPEED ( apps loading time)

• Go to SETTING>DEVELOPERS OPTION>SELECT RUNTIME.

• Click on it and change to  USE ART.

• Phone will reboot after  this. 

more info-Android uses Dalvik runtime by default, which is described as a "just in time" compiler. That means it does all of the application processing as and when it's required. Moving forward, Google is looking to use ART runtime, which is an "ahead of time" compiler. ART is actually featured in Android 4.4 already, but it's not enabled by default - you'll need to enter the Developer menu to switch it on.Your handset will reboot and it will take a short time to recompile your apps - you may even notice some stability issues - but on the whole, ART should be quicker and friendly on your battery. As more apps are optimised to use ART, you'll find it more beneficial to use.

5- SPEED UP ANIMATIONS IN ANDROID 4.4 +

• Go to  SETTING>DEVELOPERS OPTION>WINDOWS ANIMATION SCALE 

• And set it as your choice.
