For those of you who want to get Android 4.2 PhotoSphere camera on your Note 2, here’s an easy way to get it.
Step 1. Make sure you are on a TouchWiz-based Android 4.1.1 or 4.1.2 custom de-odexed ROM. Most custom ROMs are de-odexed btw. Also do make a backup ROM just in case!
Step 2. Simply flash the Photosphere zip file in CWM or TWRP recovery.
