Apple is reportedly testing a prototype of the foldable iPhone Flip, paving the way for its next battle with Samsung.

Bloomberg reports that Apple has begun initial testing of an iPhone with a foldable display. At this time, Apple is only testing a 6.7-inch display and has not created a prototype of a fully foldable iPhone. This is according to sources within Apple who asked not to be named.

This is not the first time Apple has been rumored to be working on a foldable iPhone. Earlier this month, Taiwanese website United Daily News reported that Apple had commissioned Chinese manufacturer Foxconn to prototype a foldable shell.

At this time, it is unclear what kind of foldable Apple has in the works: will it fold vertically like the Motorola Razr 5G or horizontally like the Galaxy Z Fold 2?

According to Bloomberg's sources, the current prototype has a visible hinge like the Microsoft Surface Duo.

Ultimately, it is unclear if or when Apple will unveil the iPhone Flip. Apple is rarely the first to jump on the latest technology trends, instead waiting for other manufacturers to test their ideas on the market before plucking the ideas that work best.

The Covid-19 epidemic has also hampered Apple's development. In California, engineers meet only a few times a week in limited numbers to prevent the spread of the virus. Development is left to Apple engineers in China. It also means that the chances of a foldable iPhone being released in 2021 are virtually nil.

However, rumors are circulating regarding an update to the iPhone this year. Currently, the rumor calls it the iPhone 13. It is expected to have a smaller notch and a 120 Hz display. It may also be portless, an idea that goes against all conventions. But Apple and convention rarely go hand in hand.
