Bixby Button

Does everyone else have to double tap the Bixyby button to get it to work? Mine has to be double tapped for bixby to show. won't work with just a single tap. Just wondering if this is normal or if i should warranty it. Not remapped or anything.
i remember the day i got it (unless im misstaken) i was able to tap the button once and it would show then i got an update now it takes double tap. could have been what the update was for i guess so you didn't always accidently tap it and have it...
