I don't know how many Android phone users feel when they see this report, because a study found that Android phones collect 20 times more user data than similar iPhones.
According to foreign media reports, research done by a professor of computer science at Trinity University in Dublin, Ireland, shows that,IOS and Android phones are constantly collecting data and sending it back to apple and Google, respectively. The behavior of information mobile phone starts from inserting SIM card into smart phone, including the interaction between hardware and application.
It is reported that when the user does not log in, chooses to exit data collection in privacy settings, and the mobile phone is idle, the data collection process may still run. Experts also found that IOS shares information about IMEI, hardware serial number, SIM serial number, phone number, device ID (including UDID and AD ID), location, telemetry, cookie, local IP address and nearby Wi Fi MAC address.
Android sends similar data and adds the Wi Fi MAC address of the device, but does not include the location information of the mobile phone, local IP address and nearby Wi Fi MAC address.
As for the test conditions, the test is carried out after the mobile phone is restored to the factory settings. It starts for the first time, inserts or removes the SIM card when the mobile phone is idle, checks the settings, enables or disallows the location, and collects the data for the first time when the user logs in to the own app store.
As a result, Google responded that Leith's method is flawed, and they believe that data collection is the core function of any connected device. A spokesman questioned the effectiveness of the experiment, pointing out that the experiment could not capture data such as UDP / quic traffic.
