The development team behind Replicant OS, an open-source operating system based on Android, have discovered a security flaw with Samsung devices that can provide remote access to your data. The “backdoor” is found in a whole bunch of Galaxy-branded handsets — including the Galaxy Nexus — running “most propriety Android systems.”

Samsung has today begun rolling out the Android 4.2.2 Jelly Bean update for the Galaxy Tab 2 7.0 in the United Kingdom. The update is reaching the Wi-Fi only device with the “GT-P3110” model number, and it’s available to download over-the-air or via the Samsung KIES desktop application.

In addition to Android 4.2.2 features like lock screen widgets and Daydream, the update also adds new TouchWiz features and widgets that were first introduced on Samsung’s flagship Galaxy S4.

The Samsung Galaxy S4 Mini is to launch in the United Kingdom this weekend, almost a week ahead of its expected July 5 launch date. A number of online retailers are promising delivery on Saturday, June 29, while Phones 4U says that the handset will arrive on Monday.

Prices start at £365 ($561).

Teardown specialists iFixit have published a new tablet repairability guide that quickly tells you how difficult it’s going to be to mend your broken Android, iOS, or Windows 8 slate. The guide features 18 popular tablets, which have been given a repairability score between one and ten. The higher the score, the easier they are to repair.

Unsurprisingly, Apple’s iPads are some of the hardest tablets to fix, second only to the Microsoft Surface Pro — the only tablet with a score of one. Amazon’s Kindle Fire’s, on the other hand, are relatively easy to repair, as are Dell’s devices.

Samsung has begun rolling out Android 4.1 Jelly Bean to two of its tablet in the United States. The Galaxy Tab 2 10.1 and the Galaxy Tab 2 7.0 both began receiving the upgrade over the weekend, following its debut on European devices. As you’d expect, this software comes with a whole host of new features and improvements.
