The
Nexus 9 (codenamed
Volantis or
Flounder) is a
tablet computer co-developed by
Google and
HTC that runs the
Android operating system. It is the fourth tablet in the
Google Nexus series, a family of Android consumer devices marketed by Google and built by an
OEM partner. The device is available in two storage sizes, 16 GB for US$399 and 32 GB for US$479. Along with the
Nexus 6 mobile phone and
Nexus Player digital media device, the Nexus 9 launched with
5.0 Lollipop, which offered several new features, notably a modified visual appearance, and the complete replacement of the
Dalvik virtual machine with
ART. Google has included an additional step to "Enable OEM unlock" before users can unlock the Nexus 9
bootloader.
