G8, I want to find a software that doesn't occupy so much memory, has IP display, can answer incoming calls, intercept short messages and manage online.

360 Mobile Guardian includes IP display of incoming and outgoing calls, SMS interception, Internet management and other functions, but it does not allow traffic measurement (generally higher than the real traffic, you can use SMS to check the traffic and then set it yourself). It should be said that the current flow measurement software is not very accurate, and the memory occupation is ok. I suggest setting a password to open the software (because once I was inexplicably set a password and had to uninstall it forcibly, and all the intercepted messages were gone). Never use netqin.
