Sometimes it's a good thing to take a step back and laugh at yourself. It's a humbling experience and may even open opportunities to show your customer base who you are in moments of weakness.
"Hey we messed up big time, here's the cause, here are the measures we took to prevent such things happening again. We also kindly ask everyone to consider the sensitivity of the issue regarding the affected customers" could be a good start.
Separately, IMO it's very much Streisand Effect here, as there's no way I'd've seen the GTA video without the takedown notice.
And the PR people in Samsung ... well, I'm not even sure they're having much input into what the company has done, because the whole handling of this has been horrible. They've suffered a terrible loss in brand equity, and it takes a lot longer to recover that than mere dollars.
As far as I'm concerned the Brand should "burn" for the way they've handled this and their customers.
