Sorry for the English post, I do not know chinese.
I did some reverse engineering and found the watchface files are not zip files like we have for Mi Band 7.
They are bin files similar to Mi Band 7 Pro.
So Mi Band 8 does not have Zepp OS and has OS similar to Mi Band 7 Pro.
Attaching the watchface files.
Also: screen resolution is same as Mi Band 7 ( 192* 490)
