With last month's release of the Android N Preview, the Tools team launched a preview release of Android Studio 2.1. Not only did the new version add support for the N Preview SDK, but it also brought a few important important and welcomed additions, including adoption and support for many of the language features in Java 8, a semi-official switch to the Jack compiler, an updated New Project wizard, and further improvements to the new and faster Android Emulator. As of today, Android Studio 2.1 has been promoted to Stable and is available to all developers.
The biggest advantage of updating and switching to the Jack compiler, aside from playing with new Android N APIs like Launcher Shortcuts, is probably the addition of Lambda Expressions.
It looks like the touchscreen isn't the only piece of hardware on the Sensation that works when it wants to. Posted today on XDA-Developers, Sensation owner zmfl recounted his experience with the audio signal coming and going on his phone, and having received confirmation of the issue from other members there, enterprisingly figured out the cause of the problem and its solution.
Put simply, the paint around the Sensation's 3.5 mm headphone jack tends to wear away or chip with use. This brings the pins of the cable plug into contact with the bare case metal and results in the audio cutting out or sending errant control signals to your media player.
