The trouble is that the phone doesn't always use the x3 or x10 lenses in less than optimal light and often chooses to digitally zoom instead due to the differences in aperture.
If they would give access to the zoom lenses in pro mode, you could change the shutter speed, increase ISO etc. to compensate, but they don't give enough control to the user.
I'd really like them to enable raw capture in the auto modes and proper selection of the lenses.
Edit: DXOMark camera review is up and it's not great, but i think they're using an older firmware
