While Samsung initially had a head start over other manufacturers in the foldable smartphone race, reported delays gave other companies plenty of time to catch up. Samsung had said earlier that it will unveil its foldable smartphone next month. Normally devices are released within months of their unveiling, but the case is entirely different here.

A foldable smartphone is unlike any other. Samsung has to consider a lot of things whilst ensuring the phone is durable before bringing it to the market. The unit that the South Korean giant will demo at the Samsung Developer Conference next month is likely to be a working prototype as Samsung is reportedly still undecided about certain aspects of the design of the phone. That is why it is unlikely that the device will be commercialized anytime soon.
