After making lots of enquiry at online & offline store finally got it, only a single peice was left with one of the retail samsung experience store. Most of the stores have left order with samsung & it's distributors but alas no availability so far. ...
Exactly only latest launched device's cases are available. I have S22 Ultra & it's original flip case which is tarnished now, I went to available fresh case for it, but alas nowhere to be found. @samsung what's your take on this
