We had assumed that the SM-G8750 and SM-G8850 will be marketed under the same name Galaxy Dream Lite but that may not be the case after all. Dream was the codename for the Galaxy S8 so the true name of the G8750 will be Galaxy S8 Lite according to the latest rumor. And the G8850 will be the Galaxy A8 Star.
That said, both devices should be fairly similar. They will be powered by Snapdragon 660 chipsets. Theres some confusion about the rest of the spec sheet.
TENAA has updated the original info it had on the Galaxy A8 Star and now claims a 6.28 Super AMOLED with 1,080 x 2,220 px resolution, 16 MP + 24 MP main camera, 24 MP selfie, 4 GB of RAM, 64 GB storage and 3,700 mAh battery. The original info was for a 5.8 screen and a dual 12 MP camera, which might really be the Galaxy S8 Lite.

We would point out that neither the Galaxy S8 nor the Galaxy A8 had dual cameras, but this isnt the first time that Samsungs naming scheme doesnt make sense. Also, its not clear how these two will fit with the Galaxy A6 and A6+ phones mid-range versions of the Galaxy S9 duo by all accounts (but with weaker than S660 chipsets).
