RESTRICT AUTOMERGE Fix phishing attacks over Bluetooth due to unclear warning message

Before this CL, there is a possible phishing attack allowing a malicious
BT device to acquire permissions based on insufficient information
presented to the user in the consent dialog. This could lead to local
escalation of privilege with no additional execution privileges needed.
User interaction is needed for exploitation.

This CL add more prompts presented for users to avoid phishing attacks.

Merge Conflict Notes:
There were a number of entries in strings.xml that did not exist on this
branch. However, as the CL only adds new entries rather than modifying
old ones this should not cause a problem. There were no merge conflicts
in the java files.
