The Google Nexus 5 was just released a few weeks ago, packing Android 4.4 Kit Kat. The Nexus 7 (2013) was released not that long ago, and officially received KitKat earlier today. KitKat brings a nice new feature that allows you to record the screen on your device. Previously, this required (paid) third party apps. And even then, many faced compatibility issues with certain SoCs and ROMs.
The new feature has one major down side, though. You must be connected to your PC to start the process. However, XDA Senior Member prsterero brings us a user-friendly PC interface that simplifies the process and allows you to control the screen recording functionality from your Windows-based computer. It also allows you to backup your media content and TWRP backups to your desktop PC. It does not (and is not intended to) unlock, root, or modify your device, but there are plenty of toolkits available for that already.
Head over to the utility thread for the details._________
