A hybrid app built using cordova has a display issue on Iphone

The display of the app on Iphone included black borders on top and bottom of the UI. This loads perfectly fine on Ipad. This is a new update that we are posting and didnt see this issue in the previous releases. I am wondering if any of the build settings is causing this. Can any one throw ideas on what could cause this problem? or have a solution that someone already worked on the similar issue?
