PraveenTechWorld研究团队对谷歌Pixel 8手机进行了为期72小时的网络数据包捕获测试，结果显示处于锁屏状态的原生Android设备存在大量后台数据传输活动1。研究采用三部Pixel 8手机（128GB工厂解锁版本）进行测试，期间共259,200秒无人工交互，使用企业级pfSense防火墙和Wireshark软件进行外部监听1。
测试数据表明，单部手机平均每小时向谷歌服务器发送348次后台数据包，换算每分钟约6次，24小时内超过8300次1。泄露的隐私数据包括Wi-Fi路由器MAC地址（平均每小时84.2次）、硬件指纹和SIM卡序列号哈希（每小时48.0次）、Google Photos同步令牌（28.5次/小时）、搜索建议查询（22.1次/小时）和推送通知心跳包（每小时14.8次）1。

A research team at PraveenTechWorld conducted a comprehensive 72-hour network packet capture analysis on Google Pixel 8 smartphones in their locked, idle state, documenting substantial background communication with Google's servers 1. The study found that a single unattended Android device transmitted an average of 348 background packets per hour to Google services, accumulating over 8,300 transmissions within a 24-hour period 1. Testing three factory-unlocked Pixel 8 devices (128GB each) with no user interaction across 259,200 seconds, the researchers employed enterprise-grade pfSense firewall hardware and Wireshark packet capture software to monitor outbound traffic externally 1.
The captured data revealed transmission of multiple categories of sensitive information 1. Wi-Fi router MAC addresses were transmitted most frequently at 84.2 times per hour, followed by hardware fingerprints and SIM card serial number hashes at 48.0 times per hour, push notification heartbeat packets at 14.8 times per hour, Google Photos synchronization tokens at 28.5 times per hour, and search suggestions queries at 22.1 times per hour 1.
