Microsoft didn’t mentioned clearly which devices are going to support Rich Capture support. While we do saw this is present on latest phones like Lumia 640/640XL and high end phones too. As we are deeply looking on windows 10 mobile we found that Lumia 630 now also supports the rich capture. We are not sure from which build this feature has came but noticed this in current build.
We will do some test and see how the camera performs.
Stay tuned to @WindowsLatest to get all the information that you want.
