Honor is introducing the 20i midranger on Wednesday and is already gathering up pre-orders at Vmall.com.

Today the company slipped an invitation in our mailbox, inviting us in London for the global unveiling of the 20 series. The math problem at the bottom is clue to the date - May 21.

The image showcases Tower Bridge during the day and during the night, both clearly visible, which is an obvious nod to the fact the Honor 20 flagship is expected to come with Huawei’s Night Mode. Although there is a disclaimer the image is only for illustration purposes, we expect the camera to do exactly this - take photos of landmarks with incredible details.

We are still wondering what the fours in the math equation have to do with the phone announcement, but we expect either a four-camera setup on the main phone (be it Honor 20 or Honor 20 Pro), or at least four new smartphones, including the Honor 20 Lite, rumored to be the global variant of Honor 20i.
