Don't Wait for a Foldable iPhone
Apple might be working on a foldable version of the iPhone, but there's no guarantee it releases one in 2020.
Apple rivals like Samsung and Huawei have released foldable devices. Samsung recently re-launched the Galaxy Fold and Huawei's Mate X has finally come to market. Samsung's also launched a new foldable device dubbed Galaxy Z Flip.
Nothing is confirmed, but there's a good chance Apple waits until 2021, or later, to deliver its own foldable device.
We've seen some patents hint at a foldable iPhone but this doesn't confirm anything. One analyst believes Apple will roll out a foldable iPhone in 2020 but we haven't seen any other credible sources point to a release in 2020.
Until that happens, you should operate on the assumption that a foldable iPhone is coming in 2021 or later, if it arrives at all.
