I just did compare the 01001 to 01002. And below are the differences. All photos were taken with no flash. Left/top photos are SV 01002 while right/bottom are SV 01001.
FRONT CAMERA - LOWLIGHT
REAR CAMERA - LOWLIGHT
Camera appearance and output has a huge improvement and this is because of the aperture from f/2.2 to f/2.0. Please correct me on this one.
Hope there are still ro for improvement on the front camera. Looking forward to a noiseless front camera soon.
So far so good. Hoping for the best for our beloved Flash Plus 2.
