Here is a complete step by step tutorial on how to root Samsung Galaxy S4 international version GT-I9500 on Android 4.2.2.
First day of Google I/O is officially over and a lot of great announcements were made, and some of those announcements were strictly focused towards Android developers.
Google's Maps is seen as the authority in the field of navigation, and of course, mapping, and having established a large user base already, the company is preparing to revamp the mobile arm of the service in the coming weeks and months. Following on from the new-look desktop version, Google will now be bringing the look of iOS Maps to Android, and an iPad version is also going to be hitting the App Store in the summer along with a revamp of the desktop version of Maps. More details after the break.
Hot on the heels of BlackBerry's announcement that BBM would soon become a cross-platform experience, Google has showcased its new Hangouts messaging system, unifying iOS, Android and Chrome users all in one convenient place. This revelation makes for an exciting face-off between the major instant messaging services, and it's fair to say, this kind of feature from Google as been a long time coming.
It had been rumored over the last couple of days, but Google's Hugo Barra just pulled a Galaxy S4 out of his pocket during the opening Google I/O keynote. It's not like any Galaxy S4 you've used before though, and it's not like any you've likely seen before, either. In fact, it's something hugely awesome, assuming you've got a spare $649.
Today at I/O, Google has launched its rumored Google Play Game Services, which will finally give the Android platform a Game Center-esque experience for those looking to enjoy multiplayer competition on some of their favorite titles. Then again, if the demonstration of the multiplayer feature in action today (note: it didn't connect) is anything to go by, Android users will be hoping the hit-and-miss demonstration of the service is not representative of the eventual experiences.
The Frostbite 3 engine is heavily lauded as one of the most powerful and advanced of its kind, and with the technology being the driving force behind the supreme graphics performance of Battlefield 4, it looks like a variant of the engine will soon push the boundaries of mobile gaming experience even further. EA has already indicated that the Frostbite 3 engine cannot run on the Nintendo Wii U, but the publisher remains keen to offer "true Frostbite experiences to all major mobile platforms," and with the Frostbite webpage offering details of a project called "Frostbite Go," we could certainly see some truly high-end gameplay on our smartphones and tablets.
Galaxy S4 certainly has its fair share of critics, but in terms of early sales, the latest and greatest flagship handset is a standalone record-breaker for makers Samsung. According to Korean news outlet, which has published the utterances of an unnamed Samsung executive, the company shipped an incredible four million Galaxy S4 handsets in just four days; far in excess of the early numbers of the Galaxy S III which, by comparison, took 21 days to ship just three million.
As planned, Mozilla has just dropped Firefox 21 for Windows, OS X, Linux and Android. Full details, as well as where to download Firefox from, can be found right after the break.
Saurik, or Jay Freeman to his friends, is the man behind not just Cydia but many of the inner workings of the iOS jailbreak scene. He's also the guy that brought WinterBoard to the world, the most popular iOS theming platform on jailbroken iOS devices. He's also an all-round awesome and super clever guy, which is why this next news doesn't surprise us that much.
