Lenovo is planning on launching its Z5s smartphone in China on December 6, and it could end up being the first smartphone on the market to have a punch-hole design for the selfie camera. The Z5s is expected to feature a rear-facing triple camera setup while the front-facing camera is located in the top center. Both Samsung and Huawei are expected to release products with similar design features very soon.
