What's the matter with Android smartphones automatically turning on traffic?

Android phones automatically turn on traffic for the following reasons:

1. Some malicious applications are installed in mobile phones. If these applications are licensed by the mobile phone, they will automatically turn on the traffic switch in the background and secretly transmit data. In this case, it is recommended to use the security center that comes with the mobile phone to scan and delete.

2. The mobile phone turns on the function of "always receiving MMS", so that when the mobile phone receives MMS, it will automatically turn on the flow switch to download the content resources in MMS, and turn off the button switch of this function when encountering this problem;

3. Turn on the automatic synchronization function of mobile phone, and set the automatic synchronization of mobile phone only under WLAN network to reduce the traffic consumption caused by synchronizing mobile phone data.
