This ROM has a few issues. Random reboots multiply tines a day whether you're doing something with it or not, Bluetooth randomingly disconnects and reconnects, performance drops to a crawl and then fixes itself.

This pretty much happens under slimkat as well. So for now I'm going to have to stay away from these ROMs
I need my phone to be stable.

You're way behind, this rom is switching over to a Carbon base. Keep an eye on the att thread of the same name.

Check the att threads, they get updated more often. I've been busier lately so you can even just go and check the dev host folder!

    It's all d2lte but there's also some fixes in there to make sprint LTE work. Enjoy it!

    Is there a way to kill recent apps in one fell swoop?

    Sent from my SPH-L710
    Since this is based on SlimKat I'm going to assume it uses Slim's recent apps. Finger and thumb at top and bottom, pinch together
