In Xiaomi Mi Mix 3 we have a decent ultrasound fingerprint scanner.
It works great, it has a high readability count, it is not particularly susceptible to dirt, it will read a slightly moist (but not a wet one!) finger. It is a pity that we cannot use it as a touchpad – from any other additions we have options like releasing the trigger or authorizing payments.
Xiaomi added the facial recognition system, though by using the slider mechanism this is not the most practical method, as we need to slide open the housing. Still, it works even in the dark (it simply needs to light our face with the display) and it cannot be deceived by capturing a sleeping person’s face – we need to have at least one eye open.
It is not bothered by glasses or changing the hair style – but in weak lighting sunglasses are a problem, the scanning takes a bit longer and sometimes it does not unlock at all.
When it comes to the communication side it is difficult to complain about anything. There is LTE (B20 as well), we can record calls, there is Dual SIM (passive) simple in usage, and a dual-channel Wi-Fi with an interesting feature.
After running the hotspot function, most smartphones will disconnect from WLAN networks, switching to mobile data. This one does not. So it can be an additional access point to another Wi-Fi router… Connectivity modules cover Bluetooth 5.0 (with aptX HD), NFC and GPS (2 ranges), Glonass, Galileo, QZSS and Beidou.
All modules work appropriately and did not cause any troubles in an everyday usage. I did not notice anything worrisome. Unfortunately – there is no FM radio.
The sound quality is great. The external speaker, though a single one, is powerful and clear enough. The receiver speaker – this one could have been better. Sliding the housing out helps a bit. The converter is in the “inner” part of the housing and must move through the “tunnel” above the display, which muffles the sound a bit.
When we will slide out the housing – sound waves go directly to our ear – and we can hear better. I will add that sliding the housing seems to be natural – we can take and end calls in this way. I have already forgotten how comfortable it was.
We can say that Mi Mix brought back memories of old phones… Unfortunately, the charm is gone when we try to use wireless earphones. The sturdy adapter rather forces us to switch to Bluetooth.
