Samsung started marketing their ISOCELL Vizion 33D camera in 2020 with 640 x 480 resolution. So it's likely we'll see better ToF resolution announced in some phones in the next year or two.
Thank you! Actually, my understanding when I started this project was that I would get a 640 x 480 image (IMX516 sensor). However, I could only get a 320 x 240 image from the sensor through the Android API, so that was a bit of an oddity.
Great project btw!
