How is this when running Kodi?
Much happier with marshmallow on the N7 than I was with lollipop. Interface is more or less the same, but battery life is much better.
Doze mode has me concerned (for phones) - but for tablets its awesome. I don't need it to be doing anything when I'm not using it
Why does it have you concerned?
On phones it delays notifications for Wear devices.
