The render is based on rumors and leaks, but not on the drawings
Renowned insider and designer Ben Geskin has published a couple of renderings of the Samsung Galaxy Note20 + smartphone. Geskin wrote that the novelty of the Korean giant might look like this, and in this case this is just an assumption.
The Samsung Galaxy Note20 + might look something like this
It, of course, is based on various fresh leaks, but still not on documents and drawings, as it sometimes happens. So overall, probably, Note20 + may indeed look exactly like that, but the details may differ in the end. For example, the arrangement of elements on the camera module, and the module itself may well be slightly larger.
For example, at the time, Geskin published a similar render of the Huawei P40 Pro, which turned out to be close to reality, but in the details there were still a number of differences.
