So far I've noticed 3 changes from AUBB.
1. AUBB somehow caused my phone to (again...!) heat up to roughly 45c-46c with a few minutes of video / extensive camera use. Never had an overheating warning but still 46 is not something that is nice to handle.
With AUC8 that seems to be resolved once again. Long duration video and a Wildlife stress test (20 loops) reached a maximum of 42c.
2. The obvious portrait mode change. I actually really like the ability to choose between the 3 lenses
3. Shutter is quicker with considerably reduced lag.
Anyone noticed anything else?
