Xiaomi was set to launch to the Mi 7 in early 2018, and yet the phone has mysteriously gone missing. Instead, the Mi Mix 2s was launched in its place. The current theory is that the flagship phone has been moved to a later date in order to incorporate an in-display fingerprint scanner.
A teardown of supposed Mi 7 firmware shows two different builds; with the newer version including several references to an in-display fingerprint scanner. It also mentions Synaptics, which is the company that supplied the technology to Vivo. Whether the same can be said for Xiaomi is uncertain, seeing that the firmware also mentions another company by the name of Goodix.
Xiaomi CEO Lei Jun also appears to have confirmed the rumour on Weibo. The post in question was a disassembly post of the recently launched Mi Mix 2s, where a poster was asking in jest if the Mi 7 has an in-display fingerprint scanner.
It’s somewhat difficult for us to say if this information is enough to guarantee that the Mi 7 will have an in-display fingerprint sensor. Firmware often contains leftover code from testing, while Lei Jun’s comments are by no means confirmation of any rumours.
