I confirm what Luxor says.
I'm on a rooted Note2 running DN3 v3.2 rom.
Wi-Fi enabled and configured to a working wifi router.
Installed Xposed Framework and activated it.
In Xposed Framework downloaded and installed AppSettings module.
Downloaded and installed Premium Play apk version 2.1.
Launched Xposed Framework, modules, enabled AppSettings.
Opened AppSettings module and chosed Premium Play app and set it with 175 dpi and xlarge resolution enabled.
Saved AppSettings configuration.
Premium Play works flawlessy in full glory.
So, people declaring that the device must be not rooted to run Premium Play apl is a pure false.
Thanks Luxor, I was giving it up.
