Android 4.4 KitkAt logo wood - aa

Wednesday was a busy days for updates, with Android 4.4 KitKat rollouts to the Nexus 4 and the Verizon Moto X, and a bug squashing update for Google Nexus devices.

The update, which has already begun rolling out to some users as an OTA, brings the build number to KRT16S, from the KRT16O of the original KitKat build that rolled out last week. This update applies to the Nexus 7 (2012) WiFi, the Nexus 7 (2013) Wi-Fi, and the Nexus 10.

The Nexus 4 is now receiving its Android 4.4 update, which includes the bug fixes that Google applied to the devices it updated last week. According to the changelog, KRT16S fixes several bugs related to APN settings as well as a more serious bug that Google engineer Dan Morrill called a “stop-ship bug”. According to developer Al Sutton, the critical bug relates to encryption and “could have left encrypted devices undecryptable if the user entered the wrong password after an update”. It appears that Google wanted to fix this serious problem before rolling out the Nexus 4 KitKat update, hence the unusual delay.

If you can’t wait for the OTA to arrive on your device, here are the OTA zip files that you can apply yourself:
