Lei Jun is said to have informally confirmed the presence of an in-display fingerprint sensor on the Chinese phone maker's flagship handset.
In a recently launched Mi MIX 2S, CEO Lei Jun was spotted to have replied in the affirmative to a question about an under-display fingerprint scanner on the Mi 7. However, the report suggests that this was a friendly exchange and should not be considered an official confirmation by the brand. No other features or specifications were mentioned in the conversation.

This development was recently suggested through a separate leak wherein a tipster said that the Mi 7 would sport an under-display fingerprint sensor. Xiaomi and Samsung Display had tied up for 6.01-inch OLED s back in 2017.
