Talking about the cameras, Sony H8521 Pro-A sports 12MP front camera with 4K video recording support. On the back side is an 18MP main snapper with dual LED Flash, Auto/Touch Focus and 4K video recording support. The listing does not mention dual cameras but judging from the leaks (photo above), there is a possible.
Judging from what rumors say, the SD435 is yet to be announced. If you consider that fact, Sony H8521 Pro-A is actually far from going official.
