Other specs reveal the already known Snapdragon 845, a dual camera setup (16 MP + 16 MP) and 5.6 tall screen with FullHD+ resolution. The storage is listed as 128 GB.
The screenshot says that the user interface version is MIUI 8.1, which makes the whole thing rather suspect. The company already updated 40 devices, including some 5-year old Mi phones to MIUI 9, so it’s impossible the Mi 7 will run anything but that. Still, it’s not impossible that the early software is simply misreporting itself.
