Both ROMs use Team Hacksung’s device tree, which currently has the following issues:
- FM radio is not working (when’s the last time you used FM radio on your phone?).
- Camera flash is acting wonky, but the camera evidently works just fine without the flash.
- LED notifications are inactive when the phone is being charged.
Getting around Samsung’s proprietary TouchWiz skin and related drivers is typically much easier on GSM versions of its phones, although it may take longer for these ROMs to find their way to the T-Mobile and AT&T versions due to their different chipsets. Moreover, Verizon and Sprint customers may have to wait even longer, as CDMA TouchWiz devices traditionally take longer to port AOSP to.
Please follow the installation instructions carefully for installing these two ROMs on your Galaxy S III devices, especially since the root, the custom recovery (an unofficial version of Clockwork Recovery), and the device tree are all very new.
