Meizu Pro 7 is expected to arrive this month, according to the 2017 roadmap we saw before. There were some rumors and code leaks, suggesting dual cameras and a dual display. Now we know what that means thanks to a leaked image of the back panel. The rear panel and the accompanying render reveal Meizu Pro 7 is coming with a secondary display on the back. It will be joined by the dual camera setup and it will likely be used for notifications. Meizu Pro 7 is expected to have a 5.2" display with 3D touch and 6 GB RAM.
