Sticker on back

[theobject]

First time with a Galaxy. Received mine today and am trying to figure out what this little white sticker is.

Any idea?

Thanks!

Guessing it had factory use or its for warranty. I took mine off..

Anyone know what it does? My S5 wouldn't pick it up (too small, too light)
