Have you tried posting this question on the Citrix Receiver for Android forum as well?
Is this just the standard on board browser or someting else? What version of Android?
Citrix also has a demo cloud : http://citrixcloud.net/
May help in seeing if it is a backend or device confiuguration issue.
You may want to browse around the forum mentioned. I see several comments like:
that are talking between a hotfix as well as how you have the .ICA connection configured (desktop, app, desired resolution etc). Not sure if these are relevant, old, etc - but may be another path to explore.
