Trinity College Dublin released a report revealing that after investigating the Android phones of Samsung, Huawei and Xiaomi, it was found that the UI developed by these manufacturers would be sent back to Google, FB and other manufacturers even if the user did not use it. A lot of information.

Those who will get these returned data are mainly manufacturers that have a large number of built-in programs in the Android system, including Google, Facebook, Microsoft, and LinkedIn. Through various agreements, Google and other manufacturers will build their own programs when users’ Android phones leave the factory, and sometimes they cannot be deleted through formal channels.

The investigation also found that even if the user has never used these apps after opening the box, these built-in apps will still return the user’s usage data, and the user cannot choose to close it.

In particular, this batch of data is shared, that is, the data received by each App or company is roughly the same, and it will even be shared with another company. For example, Google will share the user identification code related to the advertisement with Samsung’s server , In turn, Samsung’s App will also use Google to analyze and collect information.

In addition, Microsoft’s Swiftkey keyboard will also send Google’s advertising ID back to Microsoft’s server, as will Xiaomi’s service. In addition to the ID that can be used for advertising, such as the IMEI code, these data also include the app that the user is using, the time of use, and the length of time used. For some Android versions, a list of apps installed by the user will also be collected.

Google actually restricts similar data collection methods, but only third-party apps on Google Play, and no built-in programs are involved. The report also stated that if the data collected by the relevant platform is collected for a long time, it is enough to infer a person’s identity.
