[T-Mobile, Samsung Galaxy SIII] DigitalUnderground:
☆★☆ Known Issues ☆★☆

● GPS does work fine. If it doesn't for you, it prolly has something to do with the aosp 4.2.2 ROM before flashing this one. If u do have an issue, THIS SHOULD FIX IT(thanks mt3g)

● Dock icons aren't in dock after first boot. They are on the top left corner of the first 4 homescreen pages. Sorry. Someone please help me.with editing the CSC file defaut_workspace.xml

● Themes mess with browser just a tad bit when you want to cut or paste things but that's all.

☆★☆★☆★☆★☆★☆★☆★☆★☆★☆★☆★☆★☆★☆★

☆★☆ Tips and Tricks ☆★☆

● Inital boot up takes about 90 seconds. Please be patient.

● In developer options, change animations to 0.5 for faster, smoother performance

● galaxy s4 wallpapers are located in /system/wallpapers... use file manager for now... I will eventually get around to editing the wallpaper apk or making a new, separate wallpaper app

● Remote flash app only works if you have the PC program on your desktop as well as the app pre-installed in the ROM.

● settings>display>font style... I added the font pack so don't forget to use it :D
