The Moto X is more than nine months old, a whole lot of time when it comes to mobile technology, but some of its features are still unique on the market. Among them is Quick Capture, which lets you quickly launch the camera app with a simple flick of your wrist.
Now developer Suyash Srijan released QuickCamera (beta group required), a free app that attempts to replicate Motorola’s Quick Capture feature on just about any device.
QuickCamera is currently in alpha, so you should expect a fair share of issues with it. However, from my time with it, it pretty much works as advertised, allowing you to launch the default camera by simply rotating your phone twice. On my Nexus 5, the camera launches in about 1-3 seconds from the gesture, which is pretty good, though other users on XDA reported longer times on occasion.
Just like on the Moto X, when the app registers the gesture, the phone vibrates to alert you that the camera will open soon. This is important because, if you repeat the gesture, the app will attempt to launch the camera multiple times, slowing down the process and occasionally causing errors.
QuickCamera works both when the phone is awake and when it sleeps. The app taps into the phone’s accelerometer to detect sudden movements, and a future version will include data from the gyroscope. From the app’s Settings menu, you can tweak the movement threshold that triggers the camera launch, which may help with avoiding false triggers.
From my time with the app, there were several situations when the camera was triggered when I simply picked the phone from my desk or I moved it too fast, even with the threshold set to the max value. The app can use the proximity sensor to prevent accidental triggers while the phone is in your pocket, but it clearly needs more work in this area.
Another potential issue is battery consumption, which can really take a hit from apps such as this one.
QuickCamera is open source, so you can not only use it freely, but also incorporate it in your applications or ROM, if you’re a developer. To access it in the Play Store, you will need to join the beta community here; after that, you can download the app from the Play Store. The code source is available on GitHub.
