We have seen Per-App DPI Adjustment settings in Roms like Paranoid Android. Now it is available for everyone else in app form for the Galaxy Note 2. The Galaxy Note 2 has a huge display, but can be inefficient at displaying lots of content on that display. The default DPI settings just makes for bigger info on the bigger screen, and doesn't allow for you to really take advantage of all that screen real estate. XDA Member "Nop Ph473" has released an app that allows you to adjust the DPI settings on a per app basis. The app does require you to be rooted and have busybox installed. DPI adjustments won't work on every application, but if you experience any issues such as force closes after making your adjustment you can easily revert back to the default settings.
