Google‘s Android Security Patch for April has started to roll out for Pixel and Nexus devices. The update promises fix for a range of problems affecting the older, as well as newer Pixel devices. The security patch features updates ranging from general performance to battery, and Wi-Fi.
The fixes are for the Nexus 5X, Nexus 6P, Pixel, and Pixel 2 smartphones. In terms of the performance-related updates, the Pixel 2 and Pixel 2 XL get Assisted Dialing support, reduced delays when opening ‘specific apps’, and less battery drain after modem issues. As 9to5 Google reports, the update also improves handover from VoLTE to VoWi-Fi during emergency calls, fingerprint and keyboard latency, and magnetic sensor performance.
The update for the Pixel 2 is 76MB in size, and brings stability and performance improvements to the device. Updates common to all Pixel devices include improved modem stability and connectivity/performance on certain carrier networks, including better in-call performance.
All Pixel phones will also receive better microphone and video performance in Google Camera. The devices also receive performance enhancements for the lock screen, speaker during calls, and Instant Apps. The Settings app icons are also updated, along with fixes for call forwarding issues. Improvements have also been added to Logging, UI, Stability, Certification, Developer, GPS, and Audio.
Most of these fixes come from Qualcomm, out of which one is a critical fix for Broadcom components. The fix resolves the issue, which could potentially allow an attacker to execute arbitrary code remotely and gain privileged access. Another patch in the system prevents attackers from using exploits outside of Broadcom hardware to perform the same attack. Some fixes for the Android runtime and system framework prevent attackers from bypassing user interaction requirements to gain privileged access to a remote device, Android Headline reports.

The April security patch is being rolled out gradually and OTA is expected to be circulated within the next few weeks. However, if you want to have an early hands-on, you can do so manually. You will require a PC with ADB and fastboot set up. You can then choose to either user ADB to sideload the OTA zip file or flash the applicable image with the fastboot flash-all command. If you use the factory image method, you will have to unlock the device for flashing.
