Huawei Nova 3e, which is the Chinese name of the P20 Lite will be official next week. Obviously, one person must have handled a unit ahead of schedule and made a very short video showing off the smartphone.
From the video, the phone you are seeing is the White colour option. The photo of the Blue one was also revealed a couple of days ago and another one a few days before that. There will be also be a Gold model.
While the video doesn’t give any detail in terms of specs, TENAA had already spilled the beans, by implication giving us some info about the phone. You’re looking at a notched 5.84” screen (1,080 x 2,280px resolution, 19:9) with a 24MP selfie cam living amid the top of the screen.
Around the back, there’s a 16MP + 2MP dual camera. The software you see briefly is EMUI 8.0 on top of Android 8.0 Oreo (likely running on a Kirin 659 chipset).
