How to set up a mobile phone can reduce public information.

You can turn off some permissions on your mobile phone to prevent your public information from being leaked.

1, turn off usb debugging. Click on the set point system of this machine, and click the version number for more than 6 times to enter the developer mode and return to the system page. Developers can choose USB debugging and choose "Close".

2. Turn off sensitive permissions. Users will be asked to allow many permissions when installing applications, such as address book, SMS, call records and other privacy-related permissions should be turned off as much as possible.

3. Try not to connect to public wifi and turn on WIFI in public places. The mobile phone will constantly search around for WIFI that can be connected. Once it encounters WIFI without a password, it will automatically connect. If there is no problem with some public WIFI that needs to be logged in, if others publish malicious WIFI, there is a risk of being fished.
