member with no rep selling valuable goods...don't know y you dont provide pics and proof of legit purchase.
no rep?
Ignore all these people with the flashy signatures, they're not genuinely interested in what you're selling. They just want to boost their post count to get paid for the campaign they're participating in. Some of these people would go as far as posting complete irrelevant nonsense just to get their post count up these days.
I will take a vouch copy to see if this guy is legit.
And I don't know what this is about. You have absolutely no rep and I don't see the seller offering any "vouch copies" for his phones.
Regarding the post a photo thing. Yes, it is true that a lot of people here would post a photo to show proof of ownership of whatever they're selling, but in this case, it is a phone and seller is willing to use escrow. Unless you're afraid it might arrive damaged or has scratches then I don't think a photo is necessary. I've sold things around here without posting photos, I think as long as seller accepts escrow then it should be fine.
Would you be willing to send first?
He's willing to escrow, not sure why he would want to send first in this situation.
