This year's Samsung Galaxy Note is already thought to launch with a range of novel or updated features. They include a punch-hole camera (but in the midline of the device this time), at least 3 rear cameras and a Pro variant. Now, it is possible that it can add advanced depth-sensing and tools based on it to that list.
The OEM has reportedly trademarked something called Make & Play 3D with the European Intellectual Property Office. The documentation that goes with this apparent new filing describes it as in the category of "Time-of-flight (TOF) optical sensors for smartphones; Spatial, depth, and distance sensors for smartphones (and) 3D scanning sensors for smartphones".
This is not, admittedly, a huge amount to go on; however, the new trademark's name has overtones of a feature or function that allows the user to manipulate 3D images, possibly for the purposes of augmented or virtual reality. Should this document prove valid, this trademark has been submitted by the same legal proxy who was also involved in the trademarking of Samsung's Neuro Game Booster, which turned out to be AI-powered software to enhance gaming.
Therefore, it seems new Samsung phones may come with an app or service that makes using a TOF camera more fun. It sounds like a compelling bell or whistle for a flagship with, say, an S Pen. Furthermore, considering the Galaxy S10 5G also has such a camera, it could also be ported to this device - should it be genuine, of course.
