The iPhone X brought a massive design upgrade to the iPhone series, which means this list can't be complete without at least one iPhone X clone. The success of this design led to the manufacturing of many smartphones inspired by the same design, among which is the OWWO X. The OWWO X was released in 2018 and looks exactly like an iPhone X, including a full-screen display and facial recognition, both of which are key features that set the X apart from other iPhones.
