We have reached a point where it is safe to say that foldable smartphones are nothing new. Companies like Samsung, Xiaomi, and Motorola have already reached there. However, OPPO is the one company that has been staying in the dark, but that is finally over as the company has finally announced its answer to the foldable devices available in the market. The phone is called OPPO Find N, and it took OPPO several years to reach where they are.

The announcement is coming from Pete Lau, co-founder, and CEO of OnePlus and chief product officer at OPPO. Lau revealed through a blog post that OPPo Find N took four years to develop, the prototype was ready to back in April 2018, but the company managed to keep it a secret.
