The Android OS and its vast collection of apps allow the tablet to be a big-screen version of smartphones. The DeX computing platform, meanwhile, adds some productivity features, such as desktop-like user interface with a taskbar, windows, multitasking, etc. The DeX supports 20 windows at a time. These windows support conventional actions like file drag and drop, minimise for taskbar, maximise to cover the entire screen, etc. There is also an option to manually resize the windows.

Powering the tablet is a huge 7,040 mAh battery good enough for watching a full-length feature film in fullHD resolution with brightness and audio set to maximum, playing graphic-intensive games for an hour, streaming music for a couple of hours, and browsing the internet and social media profiles a few times in a day.
