Among the features on the device, QSlide 2.0 allows you to use two apps at the same time by making one transparent and the other solid. Using the QSlide bar on the screen, you can adjust which app is solid and which one is transparent, allowing you to switch back and forth between apps. Quick Memo allows you to use your finger to add notes and messages to whatever is on the screen, and then lets you send it to your friends and family via email, SMS or via your social networks
Also available from AT&T on Friday is the 32GB Samsung Galaxy S4. Considering the controversy with the 16GB model, which Samsung has launched with less than 9GB of available storage, we could see a migration toward the 32GB variant, especially since the difference in price is only $50. That means that the 32GB version of Sammy's new Android handset is priced at $249.99 with a signed two-year pact. At the moment, the phone is available in Henry Ford's favorite color only, 'Black Mist'.
The Samsung Galaxy S4 has its share of cool features, such as Air View which lets you open emails by hovering your finger above the notification on the screen. And using gesture control, you can answer calls and swipe pages also without touching the screen.
