IQOO7, why is there only one flash on?

There is something wrong with the flash. Redmi k50 is a new model of red rice mobile phone, and its performance is the best among red rice mobile phones. The half-open and half-close of the flash is a problem of the flash, which is generally caused by long-term use of the flash or frequent switching. This situation is irreversible, so we need to go to Xiaomi factory to replace the original flash.
