I'm currently using Android with (QV v11SR2) NTLM and Default login page option selection without any issue. Please double check your service account that used to start the QV services, especially if you're using domain account for authentication purpose.
What is your version of QV ? as I do not have the issue with the above setting and performing logon on both Android and Apple devices. Our concern is the size of the report is too small to be viewed on those devices.
Does the QV AP show you any message ?
Meanwhile, are you using Domain Account to perform the logon ?
so I understand from you that the account that is running the QlikView services should be a local administrator, belongs to local QlikView Administrators group and belongs to Domain Administrators group no?
