OnePlus 7T (Pro): Will the smartphone come with a new back?

In December last year there was a leak on the OnePlus 7T from the renowned leaker "Ishan Agarwal", which shows a photo from an internal presentation of a OnePlus smartphone. Pete Lau, the CEO of OnePlus, can also be seen on this. At the time, many doubted the leak because it looked way too "posed" and too real.
This was reinforced when the first leaks of the OnePlus 7 and the Pro version appeared, which were very different from the device presented. As a result, the leak was overlooked and was labelled as a fake - even by OnePlus.
EXCLUSIVE! Here's your first look at an upcoming OnePlus Device I don't know much about. This image shows the device in proto type/designing stage and it is not final but this is probably how the device may end up looking. That's Pete (CEO of OP) in the img and the device itself. pic.twitter.com/Yau9EsgSDy

OnePlus 7T (Pro): Schematic of the back now known
Last night the insider posted Evan Blass on Twitter a picture showing the schematic of the device. This shows a round camera design, as has been the case with Motorola smartphones for a long time.
Was that device that we saw last year the OnePlus 7T? It seems so. It is already known when the OnePlus 7T will be presented. According to information from last week the show will be in India on September 26th and for us Europeans on October 10th. Then at the latest we will see whether this really is the upcoming smartphone.
