Only a minimal options for Dell Venue 8

[sschoudhury]

HI
  I want to access my Tablet running android 4.4.2 fully using team viewer. However only a very few options are available namely Apps, Processes and settings . Even that also is severely restricted. Apps and processes have only uninstall and stop options respectively. Settings shows only available Wi-Fi list. How to access the full remote screen of my tablet.
