Android 4.3 Announced by Google and How to install it using Factory Images.

Google along with the Chromecast and the new Nexus 7 also announced the new Android 4.3 which looks same as 4.3 and you would not notice the any major difference, but their are some minor changes which would speed up your Nexus Devices. So let’s start…….

The changes which would take place in Android 4.3 are :

• Multi-Users with some Restrictions (It means now you could restrict some apps for some users)
• Bluetooth LE (Bluetooth Low Energy which would save your device’s battery)
• OpenGL ES 3.0 (Improves Graphics)
• DRM API’s (For full 1080p video streaming.
• DialPad Auto-complete (It means now if you tap on a number, a lot of suggestion with the matching number appears)
• Location Improvements (The gyroscope and magnetometer can now report raw and ostensibly more accurate data to games and apps)
• Security Improvements (The /system partition is now mounted to prevent apps from executing setuid programs (closing some vulnerabilities) and Android now uses the SELinux mandatory access control system.)
• More Languages Support Added (Africans, Amharic, Hindi, Swahili, and Zulu. Now, Android 4.3 includes better support for right-to-left text in Hebrew, Aramaic, and other languages, enabling it in more portions of the default Android user interface. The launcher, clock, Quick Settings toggles, dialer, People app, setup wizard, Downloads app, and more now support RTL displays.)
• Logging (Now Data from brought from hardware, modules, kernel functions. t’s with a built-in indicator for drawing, issuing, and waiting on commands, with the green bar indicating a 60ms threshold for the frames per second goal.)
• Disabled Tabs in Apps ( A Disabled tab is added for seeing the apps you disabled.)
