Xiaomi is among the very few companies to make use of the fingerprint scanner on its devices for more than just locking/unlocking the device. It also uses the fingerprint scanner as a shutter button in the camera app as well as for unlocking locked down apps.
Last week, Xiaomi unveiled the Redmi Y2 in India. Successor to the selfie-centric Redmi Y1 from last year, the Y2 packs in a major upgrade in almost every aspect. The selfie camera at the front has also seen a major improvement in performance which should please selfie lovers out there.
