How to unseal other people's short messages? The phone is depressing.

It will be solved by installing a communication management software. I use Netqin Mobile Guardian 3.0, which can filter spam messages, set up a black-and-white phone list, and set up interception, without worrying about spam messages and harassing calls. You can also use NetQin's mobile phone guard cclean to turn on the acceleration of the mobile phone and turn off the redundant system startup items, so that the speed of the mobile phone will be faster.
