A relatively stable test build of Android 4.3 which was adapted for the European Galaxy S4 (GT-I9505) has been leaked on a popular Samsung-orientated website, and has now been made available for the general public to download.

While the iPhone’s Retina display may no longer be king when it comes to pixel count, it’s one of the fastest smartphone displays on the market, easily outpacing all of its rivals.

According to a TouchMark test carried out by Agawi, the Retina display responds more than twice as fast as any of its rivals — including the Galaxy S4 and other high-end Android devices — even on the three-year-old iPhone 4.

Last week we saw a report that revealed Samsung’s Android 4.3 release plans for the Galaxy S4, the Galaxy S III, and the Galaxy Note II — and now those plans appear to have been confirmed by French carrier SFR. There’s good news if you’re an HTC One owner, too.

The Galaxy S4 and the HTC One are among the first mainstream Android devices to include an IR blaster, which allows the user to control their TVs and accompanying DVR by using the in-built TV app. However, the IR blaster on these handsets can act as a universal remote for any device, which has an infrared sensor, including your TV, Air conditioner, Music system, DVD players and more.

Samsung has reportedly begun preparing its Android 4.3 Jelly Bean updates for the Galaxy S4, Galaxy S III, and Galaxy Note II. All three are expected to make their way into public hands before the end of the year, but the Galaxy S4 update is likely to arrive first with a rumored October release date.
