Sourced from the developer preview factory images, the Optimus G Android L Port is now at release version 11, and it's supposedly stable enough for a daily driver. But this doesn't mean it's free of issues. Right now, the camera is throwing occasional tantrums. NFC is no-go. The phone is slow to charge and prone to heating. And the Sprint Optimus G needs you to install a fix to get cell service. Yep, sounds like a ROM for the brave!
