Barnes & Noble has decided to team up Google in an effort to reclaim its King of Book Retail title from their mutual rival Amazon.

Starting today, the two companies are partnering up to bring same-day delivery of books from local Barnes and Noble to customers in Manhattan, West Los Angeles and the San Francisco Bay area, giving both companies an answer to Amazon’s same-day offerings.

More than half a million Android smartphones across the U.S. and Europe have been infected by malware distributed by SMS, new research has found. Once the malicious software is installed, it is used to access all of the data stored on your phone that hackers might be interested in — including your text messages, call logs, contacts list, and even your photos.

Quitting and breaking the extremely addictive habit of smoking is a truly memorable achievement. It requires determination, commitment and oodles of will power — so wouldn’t it be great to have a reminder of your success in your day-to-day life? One of the main reasons, aside from health benefits, that urges people to give up is financial stability, and that’s where Stop Smoking! for Android Wear comes into play.

Now that unlocking your phone is legal in the United States, carriers have no choice but to let you use your device with other service providers as soon as your contract is up. T-Mobile is preparing to make it super simple for you to do that by pre-installing an unlocking app on your device that will remove its shackles as soon as it is eligible.

In a somewhat surprising move, Amazon is allowing all Android tablet owners to team up and co-operate with Fire TV gamers in Sev Zero, the retail giant’s exclusive game. The official companion app, which was previously available on to Kindle Fire HDX owners, can now be downloaded through Google Play.
