A second Android 4.3 Jelly Bean update for the Samsung Galaxy S4 (GT-I9505) has leaked. Unlike the first one, which surfaced earlier this month, this is not an early test version, but rather “one of the final builds.” The update is expected to get its official release in 1-2 weeks, but you can download and install it early if you know how.

Fitbit has today announced its new fitness tracker, the Force, which combines all of the features found in the original Fitbit Flex with some of the more advanced features found in the Fitbit One tracker. It costs $129.95, slightly more than the $99 Flex, and it’s available today.

Vodafone U.K. has today announced that its new 4G LTE network will be available in Liverpool, Glasgow, and Manchester by the end of this month. It’s been just seven weeks since the service took off, and Vodafone says that more than 100,000 people have already signed up to a new 4G plan.

The much-anticipated Android 4.3 update for the Samsung Galaxy S4 was leaked on Monday, and today a test version of the same update has been made available for the Galaxy Note II. If you don’t want to wait for Samsung to update your handset, then, you now have the opportunity to download and install the update manually to get your hands on the latest features.

If you happen to be a fan of what Samsung’s doing with TouchWiz, then you may be interested in a new app that brings the Galaxy S4’s lock screen to other Android-powered smartphones. It’s free and it runs on Android 4.0 Ice Cream Sandwich and above, and you can download it now from Google Play.
