OnePlus 3 render may be a decoy
Apparently, the same tactic is done by OnePlus’ sister company Vivo to drum up interest ahead of a release. Then there’s the issue of OnePlus removing features like laser autofocus and dual-tone flash, and adopting a HTC-like design.
The render does indicate that NFC is back, and that the front fingerprint reader and USB Type-C port remain. There’s no certainty that this will be the case with the final product, but it seems more likely that OnePlus would omit something that it will have than advertise something that it won’t.
