Itís clear that having a second display is a cool feature, though not everyone is convinced itís worth it. Right now its best feature is that it enables a great selfie camera while keeping the main display notch-free.
For some, the coolness factor is worth the extra cost of a second AMOLED panel. More practically-minded people did not agree and were concerned about the second display having an impact on battery life (it wonít as we found out in our review).
Practical or not, the NEX phones have established vivo as a leader in innovative designs. Remember that it was pushing in-display fingerprint readers before anyone else. And now it has a different solution to placing a selfie camera on a full-screen phone Ė donít. But thatís the topic for our next poll.
I would rather have a bezel at the top. But i don't do selfies and if i had this phone i would just slap a case on it and never see that second screen again.
The only thing I would use it for is if I bust the front screen I get a backup on the rear.
Phones with a kindle-style reading screen on the back are far more practical (e.g. yotaphone, Hisense A2 Pro)
