Stop automatically reading contacts and sending sms messages without express permission.
It is very sleazy to "harvest" or contacts and down then with text messages. You never asked express permission to do this. It should only be something you offer to opt into for specific contacts.
i installed XPrivacy as suggested. It stops abuse

After 4 years using Waze I have not seen the behaviour you describe. Are you sure it is about Waze? It could be another app you may have installed.
