Delete sample BO reports on IPAD

Hi Gurus,

When i logon to  BO on  IPAD, iam seeing certain sample reports designed by SAP in the HOME Page.I want to delete them as users will get confused on seeing those sample reports(Sales Review,Sustainability,Retailer launchpad... for example).Can any one tell me how to delete those sample reports?

And when iam trying to connect to the server in IPAD using Connect button iam able to see "SAP Analytics Gallery" where i see some more sample reports..How to disable that option so that endusers doesnt  view the sample reports in "SAP Analytics Gallery"

1. MOBI client version: 4.4.12,Build 8 (205506)

2. BOE Version: 14.0.5 and Build Number-915

Thanks and Cheers!
