Currently the KK root is on the shelf next to the donut holes, elbow grease and left-handed monkey wrenches. Which is why I'm still on 4.3. That and Safestrap. (I currently have 3 ROMS in my phone, and the stock slot is running X-Note. Stock NB4 is in a different slot.) I'm not giving that up for what might be a tiny improvement in battery life (I carry a spare at all times). And I don't have the GPS problem.
