The foldable-glass Galaxy Z flip, which resembles a large makeup compact, folds and expands to look like most smartphones.
It features foldable glass and comes in purple, gold and black.
This is Samsung's second attempt at a foldable smartphone. Last year it launched larger foldable phone with a plastic screen that was largely panned and quickly pulled off the market.
This phone, which goes on sale starting Friday, starts at a purchase price of nearly $1,400.
