Well it's small beer compared to some past retractions. My favourite is still their handling of the Galaxy S4 launch:
Customers: You advertise 16 GB but only 10 GB are available and I've filled it already
Samsung: Just move some apps to SD
Customers: There is no option to move apps to SD
Samsung: Just move some apps to SD
Customers: (more loudly, in increasing numbers) There is no option to move apps to SD!
Samsung: Issues a press release telling people who are short of storage to move apps to SD
Customers: What part of "there is no option to do that" don't you understand?!
National media: In tonight's consumer affairs programme we will report on Samsung answering complaints about lack of storage by telling customers to do something their phones cannot do...
Samsung: Oh, hang on, we've just realised that there's a bug that meant you couldn't move apps to SD. Let's fix that.
(It wasn't strictly a bug, but I'm sure they thought that made them look less incompetent than the full story would have).
It's not unique to Samsung either. I always loved the way that HTC would advertise specs on their UK site that weren't available in UK models, without even a disclaimer that those variants were only available in some countries.
