Use of the Citrix ICA client on mobile devices that have VGA resolution or larger, or companion devices such as the Celio Redfly changes the game a bit when using the Citrix ICA client to connect to full Win32 applications delivered by Citrix Xenapp. The increased resolution can leverage some configuration changes on the ICA client to get more optimal usage. Below are some tweaks that you can do to get a more “Nirvana” like experience with such devices. This setting was used in the demo blog entries previously posted.
Most Win32 applications are usable at a VGA 640×480 resolution, so I recommend running ICA in full screen mode on mobile devices that support VGA resolution. This allows the user to get rid of the program bar at the top of the screen and the navigation tool bar at the bottom of the ICA client. Comparison pictures below (Note: screen clarity is degraded in the below screen shots, native screen is clear). Caution, when you run in full screen mode, you will not have access to the local keyboard button, thus if you device does not have a QWERTY keyboard, you should have a Bluetooth keyboard connected.

To set the Full Screen option, simply follow the steps below. Note that this is a global option and all of the apps you launch will come up in Full Screen mode.
In the Programs area, start “ICA Client”:
This should launch the ICA Client UI into your browser.
Select “Edit Global Settings” from this screen:
Select “Edit Preferences” on the next page:
Scroll down to the “Enable Full Screen” check box and select it:
Scroll down to the bottom and select the “Save” button:
So if you have a mobile device that supports VGA 640×480 resolution or higher, you might try the above settings to get a better user experience. Also, if you need to access another application on the mobile device while running a XenApp or XenDesktop session in Full Screen mode, you can always hit the Windows button on your device to pull up the devices start menu as shown below.
