These solutions are unlikely to become part of the Find series, but we hope to see continuous innovation and breakthrough when using smart phones, and hope that oppo can lead this change.
The display on the back is nothing new-Meizu Pro 7 series has introduced a 2 "Super AMOLED screen, while the meter 1 1 Super Cup has reused the 1. 1" meter band 5 panel. Don't forget that there are two full-size monitors on both sides of the vivo NEX dual monitor, and each foldable mobile phone.
We think oppo can borrow the auxiliary display from the flip folding display (a small panel for notification, selfie and AOD). There is no information about whether these screens are touch-sensitive in the patents issued by WIPO.
These cameras+monitors all look cute, but there is a great chance that they are just to prevent competitors from using them. In the manufacturing field, this is nothing new, nor is it an accident. In an environment where any new design will attract a lot of imitations, oppo is just trying its best to protect itself from competition.
