Android Phones Send Data to Google Even When Idle, Study Finds

A study has measured the telemetry that Android phones send to **Google** even when they are inactive. The research analyzed network traffic from devices in a laboratory for **72 hours**.

## Secret Telemetry on Android

A recent study has focused on the amount of data that **Android** phones transmit to **Google** without the user actively using them. The research focused on measuring the network traffic of devices that remained idle, without any interaction, for a period of **72 continuous hours**. The objective was to quantify the telemetry sent in the background, which could be of interest for understanding the flow of private information.

## A Network Packet Analysis

The study was conducted in a laboratory, isolating the phones to ensure that the measured traffic corresponded solely to the device's activity and its communications with **Google** servers. Network packets were analyzed to identify and quantify the information sent. This data, collected in a controlled environment, aims to offer an objective view of the telemetry that an **Android** phone generates even when inactive, shedding light on the silent communications of these devices.

## The GrapheneOS Study

The research, conducted by the **GrapheneOS** team (an organization known for its focus on mobile operating system privacy and security), has published its findings. The study aimed to answer the question of how much data an **Android** phone sends to **Google** when not in use. The results of this detailed analysis of network traffic on inactive devices provide relevant information about the behavior of these systems regarding data transmission.
