Xiaomi mobile phone, after the corner sign appeared, all call records and text messages were gone, so please ask the guidance of the great god. How can I cancel this corner mark?

SMS cannot be recovered after deletion. I suggest you check the call list and short message list of your mobile phone, and you can find the number of the other party and the short message record you sent during the call (but the short message content is invisible).

Taking the customers of Henan Mobile as an example, customers must use "service password+random SMS code" to query the detailed list, and they can query the detailed list of the last six months (including the current month) through the front desk of the business hall, online business hall, self-service terminal and wap website. In view of the different business regulations in different provinces, you can call local 10086 to get more help manually.
