Google today made the February security patch available to its Nexus and Pixel devices. First and foremost, the patch closes a number of security holes in the code that left all the handsets vulnerable to certain types of attacks. Google plugged up issues in the kernel, framework, system, and in select Qualcomm components. The update also provides a number of feature updates specifically for Pixel 2 devices. For example, it boosts Bluetooth call quality, WiFi uplink performance, and battery performance. It also improves the camera, Android Auto, app compatibility, mobile data, and audio switching, and provides stability fixes. Last, as already mentioned, the February patch turns on the Pixel Visual Core in the Pixel 2 and 2 XL for better photography. The update is now live and rolling out to devices.
