What should I do if the SMS of QQ mobile phone tube private mailbox disappears? I didn't delete it.

Hello, through your description, please check the following reasons first:

1. Your mobile phone has been refreshed/updated/restored to factory settings, resulting in the disappearance of private information.

Solution: If your housekeeper exists in the memory of your mobile phone, it is impossible to restore the factory settings; If your housekeeper loses the information stored in the SD card, it is usually because the SD card database and encrypted files are destroyed during the operation. You can try to retrieve it through some data recovery software. .

2. You can't find your privacy?

Solution: Go to Housekeeper > Security Protection in "Virus Detection" and "Software Permission Scan", slide in the opposite direction and make a gesture of separation, and a "privacy space" will appear.

3. Other software with "cleaning" function is installed in your mobile phone, and you use this function, or you clean or manually delete this function in the PC mobile assistant software, resulting in the loss of privacy information. You can try to recover the data with USB flash drive software.

If there is nothing wrong with your mobile phone, please provide your mobile phone model and ROM version number as well as the specific version number of the housekeeper software. We will reply to you as soon as we receive your feedback. Thank you for your support to Tencent Mobile Manager!
