I have the entune software install on my Nexus 7 2013 LTE (don't ask me how, lets just say google entune apk) and just updated the KitKat Android 4.4. Surprisingly the app still launches albeit with issues like keyboard not being suppressed and user data not saved. It looks like the problem may be Nexus 5 specific. Is anyone on this forum using a MotoX or Nexus 4 that has KitKat (the only 2 other phone that has been updated)?
