Did you ever find a solution nikolawannabe, as I currently have the same issue with the current release. Does anyone know a solution to this issue ?
I'm still seeing this issue. Using Sencha Touch v1.1.0 ... have one text input field on a page. When viewed with Nexus One running Android v2.3.4 the virtual keyboard overlays the form field and obscures it from view.
I find this is only a problem but only in some cases - I am trying to find out what it is that is causing this but I have found that turning on -webkit-backface-visibility and using an actionsheet is useful
