But who cares! Here it is the way to change EACH App DPI to suite ur need of Tablet or Phablet UI.
•Click on Install/Update then Reboot.
•Install App settings module apk. You will get a notification click on that notification then tick on it to apply and reboot.
•Now u will see an app called "App settings" on the app drawer and go there select your app on which you wanna change the dpi and look. And apply the settings.
•Close the app or kill it if you were using it already.
•Remember i did not test on System apps much so test on them at your own risk.
