Doesn't really matter what the core issue is. If they can fix it via software, they're going to. The alternative is replacing hardware .... but with what ? Clearly Apple didn't do enough testing of the hardware's behavior in cold temperatures. They'd have to come up with an improved design, test it, then manufacture it. That's a 6+ month process.
What do u mean it doesn’t matter what core issue is? Of course it does?
If it is hardware and this isn’t a real fix with software lots of cold climate folks are gonna be hurting with their purchase
