Mobile phones are monitored and all text messages are seen. How to remove it?

It's amazing upstairs. Do you need to brush the machine? Landlord, the reason why the short message you said is automatically deleted is because he sent it with software and has the function of "flash message". As the name implies, "flash message" is a short message like lightning. It will not be saved automatically, but it can be saved manually. Reading can be saved according to the options. I often use it ... If the landlord doesn't believe me, you can Baidu "flash the message". As for the brush machine upstairs, it is not necessary. It can be done with a soft grid. Enter the password 12345 (if you have not changed it yourself). It will be fine after the restart. In the meantime, keep the battery sufficient.
