Had the community build of Marshmallow since that was release. This new release definitely seems a bit more stable. Love having Dose now. The one thing I'm a bit down on though is auto brightness. Feels way to lax after the upgrade to Marshmallow. I could have it under the sun and it won't get brighter for about 30 seconds+ and sometimes not at all. It was slow before the update also, but now its just borderline unusable.
Works well for me... It may be a the sourced component is not as sensitive.
I've had problems playing music on Google Play Music through my Bluetooth headphones for three months, sent in my phone many times and tried different official OS versions and couldn't get it to work until 3.1.3.. touch wood.
