It's important NOT to play up any sort of app specific functionality in this thread, as the module is "global" in scope and targets the Android framework level, as opposed to a specific app. Whatever benefit this has for you is neither expressed nor implied.
Since the module targets getDisplayMetrics() in the Android framework to adjust the reported/calculated diagonal screen size, I'm not sure that it will work on other versions of Android. Tested and working on my Nexus 5 with stock KitKat 4.4.2, YMMV.
As with all Xposed modules --> install the linked APK --> make the module active --> reboot --> profit.
Note: This module has no front-end UI, so there is nothing to do but install and make active.
Thanks to Rovo89, et al, for the amazing framework.
