Obviously the solution is to get someone to hold the phone for you or prop it up on something but I feel your frustration.
I had a problem last week with a vendor of a 3D Pen that was dead on arrival. They too wanted a video. It’s completely dead: what is there to see? Did they think I’m trying to get a replacement because I enjoy wasting my time, or did they just think I didn’t have enough intelligence to plug it in and push the “on” button? It’s almost insulting.
I ended up shooting their video only to find Amazon’s vendor messaging service wouldn’t let me post it. So I put it on YouTube and sent the link. The vendor claimed Amazon stripped the link. I broke the link up but the vendor said they couldn’t find the video (although it did get one view). Then they wanted pictures.
Meanwhile the Amazon return window is ticking down to 0. So on the last day I sent it back and ordered another one. Amazon refunded my money literally the afternoon I put it in the mail. Apparently they don’t wait for it to get back to their warehouse. They supply the refund as soon as their label gets scanned by the Post Office.
It’s for that reason that I prefer to buy stuff from Amazon.
Anyway, my issues aside, don’t give up on the printer. Keep pestering them. And for heaven’s sake, don’t throw the printer away or if you do, throw it my way
