Floating Pen Window for any App on the Galaxy Note 3
We all love floating apps. From making them to using them for productivity or leisure, they add quite a bit of functionality to the Android experience. When the Galaxy Note 3 launched with its own floating app feature called Pen Window, there was much cause for excitement. After all, what better way is there to make use of the large screen than to have multiple apps loaded and visible at the same time?
Unfortunately, the Note 3’s Pen Window feature only works with certain whitelisted applications such as the stock calculator, YouTube, and Hangouts. Luckily, XDA Senior Member soloilmeglio discovered the CSC value responsible for this whitelist. In other words, you can now unlock the feature for any application of your choosing.
Naturally, you need to be rooted and know the package name of the application you will be adding to the whitelist. Also, you must keep in mind that not all applications will play nicely with Pen Window. Other than that, it’s pretty straightforward.
