You can switch between Horizon Client and other apps without losing a remote desktop or application connection.
In a WiFi network, by default Horizon Client runs in the background indefinitely. In a 3G network, Horizon Client suspends data transmission when you switch to another app. Data transmission resumes when you switch back to Horizon Client.
The Horizon Client icon appears in the status bar when the app is running in the background and there is a connection to a remote desktop. To switch back to Horizon Client, tap the icon in the status bar.
