I got this 512GB s10+ one day ago. Happy: The phone are well packaged, and the seller, "Pro Wireless", use sealed plastic bag for all items. The items include wired AKG ear buds (thanks for seller's kindness), charger, type-c cable, usb 3 female to type-c adapter, and type-c to type-c adapter. Fireware model is G975USQS2ASGB. After a short setup, it seems it is full functional phone and worked out with AT&T as well. I did not see any problem with battery. It comes with around 50%. It can be charged to 100%. I did not test how long it will last in the run. Not so good: There are one small screen crack on the left corner. Since it is very small, it does not impact screen function. There are one significant scratch and many obvious scratch on the screen. All of them do not impact screen function as well. I believe ex-owner did not use screen protector and case to protect this expensive baby. That's why the price costs $200+ less than a new one. Regards to features and specification of S10+, I am ok with it, but I feel the price is bit of high. High end cell phone price was pushed into $1000+ and all functions aimed to be the replacement and invasion of personal life. Only history in the future can say.
