Per-App DPI Adjustment for the Galaxy Note 2
The most defining characteristic of the Samsung Galaxy Note 2 is its expansive screen. More space means you should be able to do or access more things. However, it sports the same four by four launcher as smaller devices, and many find the fonts too large overall. With the default DPI setting, the amount of information displayed on the larger screen isn’t what everyone would want. Furthermore, what works in one app isn’t always ideal in another. There is now an application that allows users to change that on a per-app basis.
XDA Forum Member Nop Ph473 posted an application that allows for on-the-fly DPI switching on a per-app basis. This is useful for users who want more information displayed in the same amount of space. Since the popular ParanoidAndroid ROM, which allows per-app DPI (as well as layout) adjustment isn’t available for everyone yet, this is the next best thing.
The application itself can be a little tricky to use. A few people have had problems getting it to work, but most haven’t had too many problems with it. Of course, you’ll need root and BusyBox at least before you get started. It requires the use of Xposed Framework by XDA Recognized Developer rovo89. It should be noted that DPI changes don’t work well for every app. In some cases, users might get off-center UIs or apps that force close after modifying the DPI. If that should occur, restoring the standard DPI should alleviate the issues.
