Get a replacement before the return time runs out. When I first got mine it did the same thing. But I kept doing the turn off and wait to cool. My return time expired. Then I had to follow all the steps recommended. Took about 2 weeks. Factory reset, Samsung support, ubreakitwefixit (which was 2 hour ride from my house and then wait 3 hours for them to work on. All they did was force updates. Got back home and over heated again. ) Report back to company after every step. They finally sent another phone but it was refurbished. I was totally upset because I paid so much to get a new phone, only to be given a used one. Plus having to reset and reload everything. Mine works great now. Just had to get past it being used. My daughter's worked great from day one.

The nomedia file is used in various folders such as operating system data folders and app folders so that when applications like gallery scan internal storage for media files they will see the nomedia file and ignore the folder and not display any media in them . Sometimes the nomedia file is missing from a folder and people report that gallery is displaying folders with images that they didn't add and have no idea where they came from.
Removing the nomedia file won't delete any of the photos and the app you're using should display them now. I would restart the phone after removing the nomedia file if the photos don't show up right away.
I have a copy of the nomedia in an empty folder just in case I need it for something.
