If anything the fact that Samsung admitted to the problem and swiftly notified customers and began the steps towards getting the replacement devices shipped so quickly has made me much more inclined to buy Samsung devices in the future.
No way would Apple, HTC or LG have done this. They would have denied, denied, denied.
I don't know about HTC or LG (I hope LG wouldn't be bad about such a thing), but Apple--absolutely. They're so wrapped up in themselves, they really think they can twist people into believing the world they want people to believe.
I say that being a Mac user since 1988. I never got into the iPhone ecosystem, though; it just seemed wrong. Of course, now I'm in the Google ecosystem, to some degree; however, I'm actively using the Microsoft stuff as well (OneNote, OneDrive) and am very happy with it and will continue with it. I try to keep Google at arm's length as much as possible. For example, I use Here instead of Google Maps, and I don't use Waze. That sort of thing.
My family is into the Apple stuff, so I've had some experience with it. For example, my father wanted a ringtone that I was using. I thought, this should be simple; I'll email it to him and save it as a ringtone. Quickly I realized that isn't how Apple does things at all, and when I discovered how hard and arcane it was to make a simple ringtone, I swore off the iPhone completely. I don't need the handholding, and I don't need the hassle of being prevented from doing such basic things as custom ringtones. Everything Apple does is aimed at making you go through their store and buy things. Um, no.
Anyway, yes, Samsung's response is a breath of fresh air. What would be better is if they offered a cheapo phone to use while you wait for your flagship device to be replaced. I know I would probably go out and buy something myself if I were in this position. I might anyway; this just brings to the forefront the idea of having a backup phone just in case, because you never know what might happen.
I just wish they would all settle down on SIM card size.
