Samsung has tackled one of the biggest criticisms of its original folding-screen smartphone by giving the new version a much bigger external display for use when it is closed.
The original Galaxy Fold's "cover screen" was a relatively small 4.6in, leading to claims it was fiddly to use.
By contrast, the Galaxy Z Fold 2's external screen is 6.2in - the same as the best-selling Galaxy S20.
Even so, one expert said its high price would mean sales remained limited.
But he noted it could act as a "halo", driving attention to other phones from the firm, including its new Galaxy Note handsets.
