Unfortunately, for your sake, it is a WP8 device. She actually had the Lumia 810 and now has the 925, which are both WP8, and their was no problem with either.

I wish I could help instead of just shooting down theories. My Mom has a WP8 Lumia also, but she isn't one for smileys. However, the next time I speak with her I will ask her to help test.
