Can't you take the battery out or does newer Samsung phones have them builtin like Apple? If you can, it seems like that should of been an allowed option since it can't catch on fire unless in use from my understanding. I wonder what happens if your on vacation or a business trip, and can't take your phone back home with you. Can you just go to any store and get a refund? "The phones also cannot be shipped as air cargo." I wonder how the returned phones will get back to Samsung, I figured the stores would probably have to ship them back to their HQ or wherever
