Smartphone makers are making bold leaps in making the foldable form factor a more mainstream one. While Samsung and Huawei have pooled in considerable resources to make this possible, others don’t appear to have the same ambitions. Fortunately, OPPO and its latest tri-fold smartphone concept will likely restore your faith when it comes to seeing unique handsets like this in the future, so here’s a first look at the company’s efforts.

OPPO has revealed that its latest tri-fold smartphone concept showcases a triple-hinge system, which is the first in the industry right now. When folded, the handset becomes quite compact, to the extent that it can easily be whipped in your pocket to be used later. When completely unfolded, the smartphone sports a 7-inch screen that’s considerably tall, giving more real estate to users and offering them more content to view.
