According to a new report, the Xiaomi Mi 7 could be the first Android smartphone to have 3D facial recognition technology. Face Unlock, a feature that has been advertised on a lot of Android smartphones is software-based. It essentially uses software to recognise the face and unlock the smartphone. However, that is not as secure fingerprint sensor hence, all Android smartphones also have a fingerprint sensor.
The sensors, essentially, throw 30000 dots on a face to map it and create a 3D image of the face. That is why Face ID was able to replace Touch ID.
The report also mentions that Qualcomm, Himax Technologies and Truly Opto-Electronics have a joint venture for creating a 3D sensing module. However, this only works on the Qualcomm Snapdragon 845 platform. Since smartphone makers use their own chipset, they won’t be the first OEMs to introduce Face ID like technology on an Android smartphone. Further, this technology won’t make it way to the market before the third quarter of 2018, which is when we can expect the Mi 7 to be launched.
