After two new KitKat builds were spotted online, with one of them apparently running on a Nexus 5 version, Myce has discovered new firmware versions that suggest the Android 4.4.3 update is imminent. A KTU83 version running on a Hammerhead device – the codename for the Nexus 5 – and identified as Android 4.4.3 has been discovered by the publication. Meanwhile, a KTU79 KitKat version for a Nexus 7 tablet has also been spotted on Google’s Chrome bug tracking board.

The codenames reveal that these two KitKat builds are quite fresh, having been created on March 24th and March 21st, respectively. Google has previously revealed that it plans to address a camera bug in the Nexus 5 in an upcoming update, but from the looks of it, more Nexus devices will be getting the Android 4.4.3 update in the near future. It’s not clear what the update will have to offer other than bug fixes and improvements.

Google is reportedly going to unveil Android 4.5 alongside new Nexus hardware later this summer. Images showing the KTU83 and KTU79 KitKat sightings follow below.
