Is it possible to hide search field and "Call History" from mobile tab (salesforce1) menu for Communities?

When new Partner Community user created by Registration Handler he get newly created Role, that reports to Contact's Account's Owner's Role.
Is there any way to avoid it?

Hi - 

Here is my scenario.. I have logged into community using an partner community user 1 and in my vf page I am getting partner community user 2 by its id and getting the related contact to it...
Even though the partner community user 2 has a contact in SF, when I query for it, the rows returned are zero. 

Is it some security that needs to be enabled for partnery community user 1 profile(the one which I am logging into community)?
