Why does my phone says searching periodically

[AC Question]

I have a galaxy note 4 and it keeps saying searching periodically, mainly at night. This just recently started a few days ago.

What does is say it is searching for? What screen are you in when it is searching for it?

Are you talking about searching for signal over Cell or WiFi, or doing a Google or other search for information that you have not asked for?
