Earlier quoted context omitted.
It would be nice to have full LIDAR based 3D scanning on phones, one for better imaging and two to provide datasets for 2D to 3D LLMs.
You have to admit that is an extremely niche requirement.
It improves general camera performance by having an accurate depth scan. Things like portrait mode and object recognition benefit.
The Measure app is quietly one of the most amazing apps in existence. You can get an accurate measurement of anything anytime! The lidar sensor makes it far more accurate and less finnicky than on the non-Pro phones.
Obviously on its own it’s not worth an upgrade but it’s a great sensor to have on a phone.
