I can back you up on that. I bought my S20 Ultra through a carrier here in the UK. My partner took delivery of the package and didn't realise the phone was actually loose. Having fallen out of the cardboard box but still contained within the plastic bag! Thankfully, and miraculously, the phone wasn't damaged at all.
I vowed from that day on that I would save up for my next handset and visit a Samsung store to buy it from.
