There have been plenty of phones and tablets with 3D camera systems. It's just not something that most consumers really want or need, so it tends not to become mainstream.
It still comes up every now and then. The iPhone 15 has a computational 3D camera thing it can do, but I've seen virtually no buzz about the feature.
No I mean true 3d by taking 2 pictures an eye length apart. Not ml based (or otherwise) depth sensor stuff.
I had a phone that took 3D pictures with a true stereoscopic camera and had a 3D display all the way back in 2011, an LG Optimus 3D. It was really neat, but 100% a gimmick because you could only share them with other people who also had the same phone or a 3D TV/monitor, and photos took up 2x as much space. You could still obviously share/view them in 2D, but it kind of defeated the point.
The one really neat feature was that it could "convert" games into 3D, which worked pretty well and was a pretty cool effect overall.
That was back when 3d TV's were still a thing, though, so not crazy
I hate that LG left the market. A LOT of innovation came from them, including a lot of quircky (and often cool) features. They experimented a lot which didn't always work out, but often it did work out great and it made their phones a lot more exciting then most other brands. Because of this a lot of features that are now the industry standard, like having a wide-angled camera lens, were popularized by LG. And yet, somehow, most people don't know this and always saw it as a lesser brand.
The iPhone 15's system will use two lenses and two sensors. It hasn't been launched on the software side, but is expected in the next few months using the existing hardware.
And it doesn't need to be an eye length apart: the parallax between two lenses can create an accurate 3D image. Apple's AR/VR system will also give a way to view/share the actual captured video, assuming it gets some level of adoption.
