The OnePlus 5T doesn't officially exist yet, but you can still pre-order it for $549 in China

After a recent leak that revealed and almost confirmed the specifications of the upcoming OnePlus 5T, almost all the details have now been listed on a Chinese e-commerce website, which surprisingly also has the flagship smartphone on pre-order at $549.[caption id="attachment_4061687" align="alignleft" width="380"] Image credit: OnePlus[/caption]Chinese e-commerce retailer Oppomart, seems to be confident enough that the OnePlus 5T exists (despite no indicator by the brand yet), so much so, that it has actually listed the yet to be announced device on its website. It's possible that the retailer has access to information that nobody else has.However, the listing highlights that while customers will be able to pre-order the 5T now, the estimated delivery date is set for the "end of November, 2017".The website only has images of the front of the smartphone, revealing the 6-inch 18:9 display, which seems good enough, since most of the changes on the 5T are expected to be only around the front face.[caption id="attachment_4176925" align="alignnone" width="1280"] The OnePlus 5T product listing at Oppomart[/caption]Peeking into the listed specifications, it reveals a 6-inch display sporting a Quad HD resolution (this should ideally be a quad HD+ unit, because of the taller ratio), the usual Qualcomm Snapdragon 835, 6 GB/8 GB RAM options and 64 GB /128 GB internal storage options. The primary camera remains at 20 MP + 16 MP dual cameras at the rear with the respective f/2.6 and f/1.6 aperture.Oddly, the earlier Geekbench leak by GizmoChina revealed a model tagged as the A5010 with similar specifications, Android Oreo 8.0 but a full HD+ display. Twitter tipster Evan Blass also confirmed that OnePlus is indeed working on a new model with an 18:9 display, that is set for release by November end.
