The Note Edge seemed to be quite the gimmick device, but it turns out the curved edge adds a really nice aesthetic. It looks much better on the Galaxy S6 Edge with both sides curved. If you wanted to ditch TouchWiz on the Note Edge in favor of AOSP you now have your chance. CyanogenMod 12.0 brings has been ported to the Galaxy Note Edge bringing vanilla Lollipop to your device.
You will need to be rooted with custom recovery installed. You will also need to be sure to do a full data wipe on the first install of CyanogenMod. The rom is already rooted, but you will need to enable the root functions in the developer options in settings. DO NOT flash supersu separately. Head to the link below to grab CM for the Note Edge.
