It's a rare sight to see a high-profile smartphone announced in December, much less so this close to Christmas, so the Galaxy A8 and A8+'s debut this week was somewhat of a nice surprise. The upper mid-rangers bring the first dual selfie cameras on Samsung smartphones and borrow more Galaxy S features than any of their predecessors.

Speaking of the Galaxy S flagships, the S9 and S9+ got their designs exposed by a bunch of case makers, who got the schematics and made renders based on them. Apparently only the plus version will have dual camera on the back with the regular S9 sticking to a single sensor.

The Nokia 9 is another hot upcoming device that made a memorable trip to rumorland. The FCC listing for the flagship revealed the majority of its key specs, which combined with some leaked design renders gave us a pretty good idea of what to expect.
