Is there some Android app, which could be installed while enabling a password - that blocks ability to bring up Dialler, Addressbook/Contacts, Messaging application screen, but still allows incoming calls to be answered ?
The idea is to provide the phone to someone who is not authorized to make outgoing calls using this phone, but should be able to answer calls made to this phone.
If similar restrictions can be put on messaging, that'd be great, but if not -- it is something that I could live with.
The password is to something that'd be known by me, but not by the person who will usually be using the phone.
Would be best if this doesn't require rooting the phone, but in worst-case, I'm willing to root the phone.
