Are there still tribes and indians in the world who live remotely from any modern civilization?

There are some tribes (If you're talking about Indians from India) who are protected from exposure from modern civilization. I've seen some rare footage on tv of some tribe that exists in Andaman and nicobar islands or Lakshwadeep islands (near India) who don't even wear clothes and look completely ancient. The Government has restricted people from going there and influencing their lifestyle. If anybody does try and go there to film them, it would be illegal and he/she would have to face legal consequences.
