Mobile phones can avoid big data by turning off cell phone permissions, turning off personalized software recommendations, and avoiding big data from software sources.

Shutting down apps that require cell phone permissions, opening the phone's settings to access privacy permissions, and opening the permissions management where we have apps that require cell phone permissions, such as location information, the camera, the microphone, and other permissions, which are private to us, suggests that we either shut them down or ask about them every time they are used, to prevent the apps from starting themselves up in the background.

For video software and shopping software we can find in the settings of the push settings, where we will see the option to push the content I may be interested in, turn it off, this is the collection of the user's favorite, we can turn off the option to avoid the collection of big data.

The source of the software is very important, a lot of unknown software is embedded with all kinds of advertisements, it is best to download it from official apps.
