After reading the text message, why did vivo automatically delete it?

If you need to turn off the automatic deletion of verification code information, please refer to the following information:

The verification code information received by the mobile phone will be automatically deleted. I suggest you go to the "information" app-click on the top right corner? Dot？ -Settings-Turn off the "Automatically delete verification code information" function.

If you still have more doubts, you can enter vivo official website-My-Online Customer Service-Enter labor and consult online customer service feedback.
