The in-display fingerprint senors are clearly going to be one of the trends of 2018. Major players on the mobile scene have yet to adopt it, but at this point, we're pretty sure it's a matter of time more than anything else. Things are lot more dynamic with Chinese OEMs who typically have shorter development cycles and less regulation and certification involved, so it’s hardly any surprise that Xiaomi is already jumping on the bandwagon.

The company's eagerly-anticipated Mi 7 flagship could have actually been delayed in order to adopt the new technology. Evidence of this was recently found in a MIUI source code branch. Today, Xiaomi's CEO Lei Jun confirmed the feature in a Weibo comment.

The exchange in question happened in the comment section of a post, containing official Xiaomi Mi Mix 2s disassembly photos. Our Chinese is a bit rusty, but from what we can gather, one of the users jokingly mentioned the feature would appear on the Mi 7, which then Lei Jun confirmed in a reply.

To be fair, the whole discussion is rather light-toned and the revealing comment does appear to be immediately followed by a dismissal, of sorts. Still, evidence seems to be piling up and at this point it's more likely that the Mi 7 will have under-display scanner than not.

Other bits and pieces the rumor mill has to offer about the Mi 7 is a trendy notched display, likely measuring 5.65-inches in diagonal. Also, a Snapdragon 845 chipset, 8GB of RAM and a starting price of around $475.
