When the Samsung Galaxy Note arrived on AT&T, the extra-large capacitive screen and S Pen were its biggest selling points. For many users, the S Pen and its button are integral to the functionality and productivity of the Note. Those who were unwilling to give up that functionality have been forced to stick with stock ROMs. All that has changed with the newest version of ParanoidAndroid for the Samsung Galaxy Note i717, brought to us by XDA Senior Member JamieD81.
The ROM is based on Android 4.1.2, and features full support for the S Pen and the gestures that can be done with it. This is exciting news for the i717 community, to say the least. ParanoidAndroid 2.21 has a host of other features as well, including Google Now compatibility and a layout switcher that allows users to select between phone, tablet, and phablet UI modes. You can even set different UI modes on a per-app basis (tablet-mode Youtube, anyone?). If you want to give it a shot on your Galaxy Note i717, be sure to make a full backup of your device, and then head on over to the release thread.
Update: Please be aware that the S Pen features are still under review by the CyanogenMod team. It appears that the code may allow for an exploit of the screenshot function. The S Pen functions are still under review and have not been committed to the CM source code. JamieD81 (who based his work on Paranoid Android, which features code based on CM10) has decided to include these features early. If you understand the risk and still wish to continue then by all means, do so. When the CM team commits the S Pen code, you can be sure to read about it._________
