The punch-hole display like the Honor V20, slider design like the Xiaomi Mi MIX 3 and dual display like the Vivo NEX Dual Display have respectively received around 17 percent, 16 percent and 9 percent votes.
As mentioned above, Jun voted for waterdrop-style display which suggests that the Mi 9 could be arriving with such a display to offer higher screen space than the Mi 8 that featured a wider display notch. In the recent past, Jun has revealed that the Mi 9 would be equipped with faster charging technology.

A new Xiaomi phone with model number M1902F1A/T that was approved recently by 3C authority in China was found to carry support for up to 27W fast charging. It is speculated that it could be the upcoming Xiaomi Mi 9 flagship phone.

The handset is likely to come equipped with an in-display fingerprint reader. Compared to conventional in-screen fingerprint scanner enabled smartphones, the Mi 9 is expected to offer larger screen fingerprint unlock area of 25 X 50.2mm.
