Strange icon in my notification bar

[Android Central Question]

So, I have a galaxy s9+ and I think about 3-4 days ago I started to see a new icon pop up from time to time in my notification bar, next to the clock, but it stays there for a maximum of 1 second, and I never get to pull down the notification bar and see the description of it. Only one time I briefly saw it and it had the word "transfer" into it, but I didn't see more. The icon looks like a phone and on the left side it has some lines, similar to the Wi-Fi lines and on the right side it has 2 arrows similar to the mobile data arrows. Is there any site that explains all the icons of notifications? Or does anyone know what that icon means exactly and what could trigger it? Thanks at all! Have a great day!

Being on the left side it could also be an update or sync process ruining in the background.
