Xiaomi is known for its MIUI Android skin, no surprise considering it started off as a company developing MIUI for other OEMs. While we don't think MIUI is bad, that isn't an opinion shared by a large portion of the enthusiast community, and it made a lot of sense to everyone when Xiaomi launched its first Android One phone, the Mi A1, back in 2017. Since then, the company has launched two other Android One devices, the Mi A2 and Mi A2 Lite, and it would seem that it plans on releasing two more entries this year.
XDA-Developers has discovered references to two Android One devices in Xiaomi's data. The devices are codenamed “bamboo_sprout,” and “cosmos_sprout”, with the "sprout" suffix a tell-tale indication of the devices being Android One offerings.
The devices are also being tested with "fod", a term vendors reportedly use to refer to fingerprint on display—or in-display fingerprint readers. Considering how Xiaomi's Android One phones so far have all been mid-range or budget devices, we're not sure why they have in-display sensors. For one, most in-display readers are much slower than usual capacitive ones.
There's also reference to a device codenamed "pyxis". That isn't an Android One phone. The aforementioned phones are likely the Mi A3 and Mi A3 Lite, and we wouldn't be surprised if “pyxis" turns out to be the MIUI device the Mi A3 is based on. An Mi 7X, in all likelihood.
The three devices are expected to feature 32 MP selfie cameras—a feature that appears to be the rave of the town right now. The devices will use pixel-binning to shoot 8 MP images with more detail, though.
