I'm not seeing anything but boxes with numbers inside for all of these smilies.
I've actually thought of starting a thread about the addition to every post that amount to nothing more than free advertising and an annoyance. It would be ridiculous for all of the rest of us to start adding the same useless information, although the software and device sellers would be happy.

I can't see the smiles in your post but boxes as you describe. I don't think anyone is attempting to advertise anything in particular, the thread is about tapatalk which is a mobile application which allows access to forums when we're not able to access a PC. I'm guessing that whether smiles display properly is dependent upon the device used and the appropriate keyboard saved onto the device.
It's obviously a pointless exercise using emoji icons if only a few can see them, thanks for pointing this out.
