I must confess, I've never seen the appeal of Twitch: why watch other people play video games when you can play them yourself, on the thing you're using to watch them? But enough other people seem to enjoy it that Amazon gobbled up the livestreaming service, and now something very similar has come to Android. Shou.TV is a beta app and service that basically does exactly what Twitch does, but on your phone instead.
Sony's oddball external smartphone cameras have a lot of shortcomings compared to a conventional point-and-shoot, but they're getting a little better today. The manufacturer has released the 2.0 firmware for the QX10 and the more expensive QX100, boosting their video recording capabilities and low-light sensitivity.
Video recording for both models has been expanded to 1080p at 30 frames per second. Formerly it was 1440x1080/30, the 4:3 aspect ratio equivalent. The shifted resolution should make videos taken on the QX cameras match up with most phones, HDTVs, and 16:9 monitors.
Android has had native support for user-taken screenshots since 4.0, and a few OEMs like Samsung have had supported the feature even before that. But until now, getting a reliable video recording of your device's screen has been a major pain, usually requiring some kind of root solution that doesn't work for all hardware. In KitKat, Google is doing away with that, allowing end users to record video directly from the screens of their devices.
