Here's the first video of the vivo X20. It doesn't divulge much in terms of specs or features but does show the phone from both sides (we have seen it in stationary form). Meanwhile a slide seems to confirm that the phone will have 24MP cameras on the front and on the back. What the resolution of the second camera on the back will be is unknown. What we do know so far is that the vivo X20 will have an 18:9 5.8-inch display with a 1080x2160px resolution, 6GB of RAM, 64GB of storage and a Snapdragon chip (likely a 660). Thanks for the tips, everyone! Source 1 | 2
