It’s one thing when an Android application adds support for new versions of Android or Android devices. It’s another thing altogether when an application developer makes an application compatible with specific features on a particular Android device. And it’s even more exciting when that feature actually rocks.
For users of the Samsung Galaxy Note, there’s an application updated just for you. XDA Senior Member Volker1 has updated the Quill application with S-Pen functionality. The app also supports active pen input on the ThinkPad Tablet, HTC Jetstream, and HTC Flyer. It doesn’t end there. There are a plethora of features in addition to S-Pen support including:
Active pen (digitizer) support on ThinkPad Tablet, HTC Jetstream, HTC Flyer, and Galaxy Note.
Very fast response to pen strokes.
“Fountain pen” mode supports pen pressure data, more pressure = thicker line.
Double-finger tap to zoom.
Two-finger move gesture.
Pen strokes are vector art, zoom does not pixelate your writing.
“Pen only” mode (optional) disables touch input while writing.
Android 3.x hardware accelerated graphics.
Open source (GPL), so your notes are not stuck in an opaque file format.
A couple features of note are the pen pressure data, and that the artwork is stored in vector format rather than being rasterized. For the pen pressure data, it actually accounts for how hard you press on the screen to determine the thickness of the line which is on its own a cool feature. For the vector images, well it’s pretty self explanatory. Just keep zooming, no pixels! Of course, to take full advantage of the application, your device must be running either Honeycomb or Ice Cream Sandwich.
