Re: Bullshit
I suspect agile methodologies on a completely new hadware design don't quite cut the mustard - it's quite difficult and expensive to iterate forwards.
In which case, the next step once "development" has been completed is testing. I suspect they're going to be quite careful of putting this into the field until rigorous testing has been completed - they don't want to get burnt (literally and metaphorically) as they did before with the Note 7, particularly as this is likely to be part of a flagship product
