An Optimized Stock Experience!
The main purpose of this ROM is to deliver a ROM that makes the device the way it was meant to be.. that includes all of the stock features while at the same time removing as much garbage as possible (ehem... VZW...) and with optimizations.

IF HD CALLING IS NOT WORKING
HD Calling is working on my phone. It may not work on yours. Don't ask why, I don't know. Things to try:
- Clean flash OG5 ODEX rom and ensure HD calling is activated and working. Then dirty flash OR15-1 DEODEX latest build.
- You may have to reflash to NCG stock system. Activate HD Calling, reroot and upgrade directly to OG5.
- Still not working? I don't know...
