That's funny because it worked on my old s3 too. The code thing annoys me when I'm using a different computer. It takes roughly an hour for the code to be sent.
I tried typing it multiple times. I even turned off the auto caps on my phone. It worked on my s3 about 2 days ago. Could it be a problem with new phones?
Is anyone having a problem using gateway while on a phone? I'm on my note 4 and when I try to enter my password it says that it's incorrect but when I go on my computer it goes through just fine.
