Htc G6 SMS disappears automatically. What happened?

It may be that the antivirus software of mobile phone 360 has no trace of SMS. This function is a short message on the screen of your mobile phone. Press the back key and it will be deleted automatically, leaving nothing behind.

If 10086 automatically disappears, then there must be some software with malicious plug-ins in your mobile phone.

There may be a charge for using this software. In order not to let you find out, your 10086 information has been blocked.

My mobile phone used to be like this.

What you said is not specific enough. I just want to get these two situations.
