Honor has scheduled an announcement for December 10, breaking the news through a teaser post on Weibo.
The Huawei nova 4 with an in-display selfie camera is coming on December 17 and the flagship-grade Honor View 20 (again, with an in-display camera) will drop at an event in Paris on January 22. We're sure Huawei didn't choose the December 10 date by accident - Samsung's first Infinity-O smartphone, the Galaxy A8s, is coming on December 10.
Honor teaser for December 10
If the promo poster isn't meant to tease a smartphone, we could be looking at a promo for Huawei's GPU Turbo 3.0.
In any case we should know more this coming Monday - December 10 - which is shaping up to be quite the interesting day.
