My air command in galaxy note 5 wont show up anymore?!

Help!
I have a samsung galaxy note 5 and I accidentally put the S pen backwards. It kinda stuck for a while but luckily it could slide out after I tilt the phone down.

But after that incident. For some reason the floating icon of the air command was still there even after I put the S-pen (correctly) back in. So I went to the settings and turned off the floating icon.
Butttt the floating icon wont show up anymore even after I detach the S-pen and after I turn on the floating icon again.
I cant even jot down notes when the screen is off!
I think I broke the S-pen what should I do:'(
