Note that, as the Note 8 uses 213 dpi, these apps work well at that dpi. It will work on devices with 213, 220 & 225 dpi Phablet and Tablet. Also, you can try these apps on lower dpi devices (320/240 dpi), if not working you can use Xposed Framework and App Settings Module to set the dpi. The apps includes the following: S Note, TW Launcher (native dpi is 213), Awesome Note, S planner, Music Player, File Manager, Task Manager, Alarm, World Clock, MMS, Email – Sec Exchange, Gallery, Video Player, Weather Widget, Flipboard, Browser, Calculator, Samsung Apps Tablet, Download Provider UI – white theme, Digital Clock, Dual Clock Digital, Wallpaper Chooser, Samsung Widget Program Monitor, Yahoo News and Polaris Office.
Important: Don’t forget to delete the corresponding stock app from system app folder to avoid any possible conflict. Galaxy Note 8 System Apps and Wallpaper can be downloaded from this XDA forum thread.
