Where have I ever said it wasn't a true upgrade? No please, quote me where I've said that it isn't an upgrade... I've even said it would have been nice to have it, if only for future proofing!I'd argue that Alexa is further along, at least when it comes to 3rd party integration. You're also forgetting that with BT 5 you can connect to two devices so you could also wear something with your Sp02 levels if that's really important to you. I think at this point, you're just really grasping at anything to justify BT 5 not being a true upgrade to 4.2
I think you're just starting to troll because I have pointed out that assistants can't YET do as much as you want them to, so I will wish you good luck and if you're that upset about not having BT5 then why not go for the S8 or Xperia XZ Premium?
Have a nice day! ?
