The foldable phone market continues to skyrocket, with more than 7 million flip and fold units sold in 2021 alone.
That's an increase of over 260% from the 1.9 million models shipped in 2020, according to a new report from telecom market intelligence firm International Data Corporation, which projects that around 27.6 million flip phones will be sold in 2025 at a total estimated market value of $29 billion.
By 2025, fold and flip phone market share could more than triple, according to IDC, representing 1.7% of all mobile phones.
IDC places the model's rapid growth squarely at the feet of Samsung, which released the crowd-pleasingin August and is expected to drop the later this year.
Though the Korean tech giant hasn't released hard sales figures for its foldable phones, it says sales of its foldables quadrupled in 2021.
Foldables are still a small part of the market -- just 0.5% of the phone market in 2021, according to IDC -- but Samsung is managing to peel consumers away from Apple and other competitors.
According to information from its trade-in programs and other retail data, Samsung has seen a 150% increase in customers who switched from other smartphone brands to one of its foldables, compared with those who switched from its Galaxy Note 20, AndroidCentral reported, and a 140% increase compared with those who switched from the Galaxy S21.
Samsung's latest launches shattered the two biggest roadblocks to the uptake of foldables, said IDC research director Nabila Popal: "rocket-high average selling price and concerns around durability."
"With their latest devices, Fold 3 and Flip 3, around the $1,000 price point -- and massive improvements in durability -- they showed the world that there is a healthy, even if still small, demand for foldables," Popal told CNET. "In just one quarter, they helped triple the worldwide volume. To me, that is a successful launch."
The largest chunk of foldables, about 35%, are in the US market, she added. "There were really strong promotions and trade-in offers with the major operators in the US which really helped."
Samsung didn't immediately respond to a request for comment.
