I don't understand the Samsung spider cell phone commercial?

Is the woman screaming because she wanted the phone so bad that she was surprised that her husband or bf put it on the table?

Seen here.

Or is it because of the spider, that looked too real? I can’t tell if she’s screaming because of joy or fear.

I don’t quite understand the deal with this commercial.
