When first showed off its thinly bezeled Mi Mix concept back in 2016, it became a template of sorts for phone manufacturers looking to produce phones with smaller bezels. But the Mi Mix concept was about more than the amazing (for the time) 91.3% screen to body ratio. It was housed in ceramic, and the piezoelectric speakers generated sound from the handset’s metal frame. Xiaomi designers moved and removed the sensors located on the top of a phone allowing the bezels to be reduced in size.
