1. GOOGLE NOW:- Google's latest mobile helper is an extension of Android's Google Search app. Google Now expands the personal assistant concept popularized by Apple's Siri by anticipating your needs and providing useful information at the right time. It does so by automatically displaying "cards" that contain location- and time-relevant details. When you're at the airport, for instance, Google Now will find your boarding pass in an email and post it on your smartphone's screen. (As of mid-December, this feature works with only a limited number of airlines.) Google Now debuted in June 2012 at Google I/O, and is currently limited to Android 4.1 and up. It shows great potential to make mobile devices much more intelligent and useful.
2. GOOGLE DRIVE:- Google Drive isn't new, of course, but its recent upgrade allows you to edit Google Sheets (spreadsheets) on your Android phone or tablet. The Drive app now boasts additional desktop-like functionality as well; you can create a new spreadsheet, edit an existing one, and see other people's edits in real time -- handy for working collaboratively when you're on the go. You can resize columns, change fonts, sort data and so on. Another nice touch is the ability to add a home screen shortcut to any file in Drive. The smartphone may never be the go-to device for spreadsheet jockeys, but Google Drive's upgrades certainly make it more useful for number-crunchers.
3. PHOTO WALL FX :- Your Personal Wallpaper Gallery. Showcase an animated collage of your favorite photos on your device's wallpaper with Photo Wall FX - a live wallpaper app that does exactly that while consuming very little battery. Photo Wall FX is a live wallpaper app that showcases your photos in a collage format with several layout styles to choose from. Want to add an entire album, to apply some cool image effects or just double tap on any photo to share it or view it in full screen? This app does them all. Photo Wall FX has been optimized for both smartphones and tablets that has live wallpaper function with options to choose both portrait and landscape layout styles.
4. AEGIS :- Lost your phone? Want to get an exact GPS location... or better yet, wipe it clean? That's the idea behind aeGis. Set up a few PIN-enabled security measures in the app, and if your phone is lost or stolen, borrow someone's device to text yourself. Send the code and you'll get a location, or lock it down, or erase all of your personal data. AeGis is an OSS alternative to other security apps that interact via SMS. aeGis allows you to lock, locate, wipe, and alarm your phone via configurable SMS passphrases. If your phone ever goes missing or is stolen, simple text the passphrase you chose to your device to activate any of the four options. aeGis source code can be found at http://github.com/Decad3nce/Aegis.
