Google has announced the latest Android 4.2 Jelly Bean OS and latest Nexus devices for days. While Android 4.2 isn't a major upgrade, it does bring significant improvements to the popular, open-source mobile operating system. Some of the Android 4.2 upgrades are minor. Sure, it might be nice to use the Photo Sphere feature to stitch together photos to from Google Street View style panoramic images, but you're not going to do that more than once every blue moon. It's also nice that the 4.2 Play Store app includes a personalized music-shopping function, Music Explorer. Other new features, however, will want you to make the jump. Today, I would like to make a simple interpretation of Android 4.2 Jelly Bean OS new features.
Multi-user support: On Android 4.2-powered tablets, but not on smartphones, you'll be able to have multiple users. Each user will get his or her own setup. That means, for example, you can have your own home-screen, background, widgets, apps and games, while your spouse or office partner can have their own unique tablet experience. You can set this up so a new user must login to the tablet or they'll be able to simply hit a button and away they'll go with their own tablet take.
Miracast: From Tablet and Smartphone to TV: Miracast is the trade name for Wi-Fi Direct or WiDi. This is an 802.11n compatible network protocol for display-sharing. With a compatible device or a Miracast adapter, you'll be able to stream Internet TV shows and movies from your smartphone or tablet to your TV. Miracast adapters will be available this quarter.
Gesture Typing: If you use Swype, you'll find the same basic functionality to make on-screen keyboards more useful in Gesture Typing. This probably won't be enough to sway hard-core Swype users away from their favorite virrtual keyboard, but it will show screen-typers that there is a better way than using a display keyboard than just as a QWERTY glass keyboard.
Smart Screen-Savers: Android 4.2's Daydream is actually a smart screen-saver. It lets you display photo slideshows, news headlines, and the like.
Google Now update: In the updated Google Now, the app could help you check your ticket, order, hotel, etc. and remind you upon pre-set time. But these functions require authority. Meanwhile, Google Now also added to display movie, concert, stock and news.
Quick Settings: Another advantage of Android 4.2. When you drag down the notice board with a single finger, it would display Wi-Fi, Bluetooth, brightness, battery, Flight mood and a button to enable you enter the full settings. But when you drag down the notice board with two fingers, it would be a short-cut towards quick settings, which will be quite convenient for those who change settings a lot for various purposes.
HDR Mode: This is the first time for Android cameras to have HDR mode. HDR shooting requires at least two shots for the same scene. The images captured will melt into one single picture in different exposure. This would make exposure more reasonable for the bright and dim parts of the images.
