Android deployed its recent patch for their phones. This patch holds significant updates, that involve KRACK (Key Reinstallation Attack) and also some fixes for the newly released Pixel 2 phones!
Surprisingly, Google actually released three updates for November. There is the main update that involves the normal bug fixes and performance updates. The second patch is in relation to the Qualcomm bug that left users vulnerable to Wi-Fi breaches.
The Qualcomm bug comes second to the Krack update. Earlier this year a weakness was found in the WPA2 Protocol that put thousands of people in a vulnerable position, allowing them to be hacked through most all Wi-Fi points. Krack is all about that new vulnerability in the WPA2, those most vulnerable however would be the Linux and Android 6.0+ devices, this is because their system can be tricked into installing an all-zero encryption key.
The 2017-11-06 patch that addresses KRACK issues affects versions ranging from Android 8.0 Oreo and all the way back to 5.0.2 Lollipop. As for Google’s Pixel and Nexus, the patches thus far released are only up to 2017-11-05, so the KRACK update has not hit those customers yet, but it is presumed they will receive the 2017-11-06 update sometime closer to December.
Along with bug fixes and security reinforcement, Google is now adding functional updates in the mix. When the Google Pixel was released, the XL variation received a lot of criticism due to the screen brightness and burn of the battery that occurred passively. To help diminish these concerns, Google updated the phone with new functionalities. The first would be a new dimming navigation bar, that dims the navigation bar when it is not in use, while also changing to white while in some applications. The patch also lowers the max brightness.
Another complaint was the colors of the display were dull. It seems Google anticipated this possibility and had installed a “Vivid color” check box in the settings menu. However this saturation wasn’t enough for some customers so Google released a new “colors” option that gives three options for saturation, ranging from natural, to saturated, to boosted. Supposedly there have been reports of clicking noises while on the phone with the Pixel, but Google states the November patch fixes that as well.
