Another video released last week, also supposedly the "iPhone 7". He showed speaker holes misaligned with each other, suggesting that the housing comes from a preliminary design of a manufacturer, or is false.
The alignment of the speaker holes in the latest video, however, is much more accurate, yet the headphone output is absent, confirming earlier published images.
The video resolution is the maximum allowed for the Chinese social network (320 by 240 pixels). As an effect of low resolution when the orientation of the phone the parallax effect of iOS wallpaper is altered is not visible.
Apple is expected to launch the "iPhone 7" this year, probably in September.
