According to reports, Oppo's product manager humorously mentioned that numerous working prototypes are tucked away in his office drawer, showcasing the company's commitment to innovation despite the challenges.

The primary reason behind Oppo's hesitation to release these devices for sale is the cost. While competitors like Huawei and Samsung are progressing with their own tri-fold offerings, the manufacturing expenses are staggering. As a result, the retail prices would be equally high, making them out of reach for many potential customers.

Here are the current voting results:

By keeping these tri-fold prototypes under wraps, Oppo is strategically waiting for the costs of materials, such as flexible screens and intricate hinges, to decrease. This approach will enable them to introduce a product that is accessible to the average consumer, rather than a niche luxury item. With any luck, we can expect a more affordably priced tri-fold smartphone in the near future, which would significantly disrupt the market.
