The hashtag is pretty curious - #oo. Unless all rumors about the P9 so far are wrong, the phone will feature a dual camera setup, which can fairly accurately be rendered in ASCII art as oo.
We expect to see multiple versions of the P9, allegedly four in total. The mainstream model will have a 5.2" screen and a Kirin 950 chipset, then there's the P9max with a 6.2" QHD+ screen, a P9lite isn't out of the question either.
Thanks for sending this in, Momchil!
