PeopleStrip is a component of your Samsung Galaxy S6 and it's part of the operating system. The application has all the permissions above because it's used to handle contacts and the operations available for contacts. You will have to keep it installed on your phone. Additionally, to clear it from any errors, go to Settings > Apps > All tab > PeopleStrip. Tap on it then tap on Clear Data and Clear Cache. You can Force Stop it as well, but reboot the phone afterwards.
