Memory contains images

The Wi-Fi connection requires installing a Wireless Mobile Utility to the smart device prior to use. And the Utility must be On.
Compatible OSs: iOS 6.0 or later, Android 2.3 or later

The Wi-Fi connection will be disabled if:

• The battery charge is low
• A memory card is not inserted
• An Eye-Fi card is inserted

You can consult the user manual for further troubleshooting at:
Nikon COOLPIX S9400 S9500 Reference manual Nikon Knowledgebase

Page 27 of the user manual says:
Lower the flash by gently pushing it down. When not taking pictures, lower the flash.
The manual is online with Nikon USA. but here is the picture of that page. See bottom of the page.

Call Nikon they can fix it they ask you to send it to them and they tekk you how much you send it and they fix and mail it back it shouldnt cost that much nothing is broke.

Your camera uses a different filing system than the other camera...they are not interchangeable.

You may refer to this camera photo recovery guide that helped me before
Recover images from digital Camera

I think you may have deleted the folders from your memory card.  The camera could be looking for the folder to put the photo into, and this error comes up instead of one about the folder.

Are you able to access the images using a card reader on your computer ?

Thanks! I'll give that a shot.

Try Reformatting the card in the camera . Then come back
