Meizu will unveil the M6 Note on August 23 and will "debut an exciting new camera feature" - which is likely a dual camera. This information isn't surprising as we've seen the dual camera in a leaked photo and the 23.08 announcement date courtesy of leaked press invites. The Meizu M6 Note will have a 5.5" 1080p screen and will come with either 32GB of storage and 3GB of RAM or 64GB/4GB combo.
