Xiaomi announces the 4th iteration of the Mi Band fitness tracker-- the Mi Band 4, an update featuring a full-colour 120 x 240 resolution AMOLED touchscreen and a built-in microphone enabling voice control.
The introduction of colour to the touchscreen allows Xiaomi to add no less than 77 different watch faces, allowing customers to customise the look of the device. A 2.5D glass cover protects the screen from scratches, and the tracker sits in a silicone strap similar to the one included with the Mi Band 3.
