My BB keyONE was instant as well. The only reason I got the S9+ was I was heading out for a couple of weeks vacation when the BB screen came off--like they all did. Costco was having a blowout sale on the S9 family (this was June, after a March launch--that's how Samsung rolls, look for incredible deals on the S20 family soon now) so I grabbed it--and loved it. Grabbed the 10+ at launch, and frankly, have wished I'd have kept my S9+.
I still have my BB. TCL fixed the screen, no problem.
So yeah, I'm being kind. Sammy knows how to do a good FPS. TCL made a superb system with the keyONE's spacebar. But Sammy released this thing that really isn't great for the purpose for which it was intended, a problem magnified by the fact that Sammy's face recognition isn't secure enough for Google/Samsung Pay and 1Password and the like.
