So far, I'm noticing:
- Bootanimation isn't the correct size for the N4 screen. There are black bars on the sides.
- Settings > wireless > mobile network > access point names; I can't select the APN that's there to change it. I can only add a new one. But after adding it, I can't select it again to edit it. I remember this was a bug in the early AOKP unofficial builds. They got it fixed eventually.
- RAM bar in the Recents list does not report the same RAM usage as in Settings > Apps > Running. The Recents RAM bar shows much more. Some of the current AOKP builds are experiencing this too. Some are fixed.
Will update if I notice anything else.
