I pre-ordered the S21 Ultra 512 GB in Phantom Titanium with the understanding that it wasn't expected to be delivered until March 2nd. Samsung emailed me over the weekend saying my order has been delayed for more than 30 days. I'm afraid this is the first step for them to cancel my pre-order. I will be patient and wait as long as I eventually receive my order. Has this ever happened to anyone before and you still received your full order? I would love to hear that I have nothing to worry about.
