Wait for Face ID Improvements
It looks like Apple will make improvements to Face ID as well.
According to Weinbach, the company is preparing an upgraded system that lets you use wider angles when unlocking your phone.
This is the first time we've heard about this upgrade so take the news with a grain of salt.
That said, if you're unhappy with the current state of Face ID or simply want the best experience possible, think about waiting a few months.
iOS 13 will bring improvements to Face ID as well.
