Apple has hinted for the second time that foldable iPhones could become a reality.
The company could be contemplating folding touchscreen technology and unlike the iPhone 6, it is designed to bend.
The US Patent and Trademark Office recently published Apple's patent application for "an electronic device [that] may have a flexible portion that allows the device to be folded", according to CNN.
Apple has been granted patents for foldable products since 2016.
Flip phones were popularised in the 1990s, but have experienced a sales uptick in recent years, especially in Asia.
Meanwhile, celebrities from Rihanna to Anna Wintour have been spotted with feature phones, rather than higher tech models.
The iPhone may not be the only device ready for a 90s makeover.
Samsung is expected to unveil a foldable Galaxy X and a new Galaxy S9, reports Forbes.
The company plans to use “bent areas” on the main display so it can curve 180 degrees around the top, bottom and sides of the smartphone.
Further reports have indicated that LG also has plans to release a phone with a foldable display.
