If you are using a vivo phone, please turn off the device first, do not use it for the time being, and immediately take the machine to the vivo customer service center for testing (customer service center address: go to the vivo official website /vivo mall APP-My-service outlets/after-sales outlets-select provinces and cities to inquire about the customer service center address). It is suggested to call the customer service center in advance to confirm the relevant matters and know that the working time is coming, so as not to delay precious time.
