My blue-tooth wouldn't work well with many of my devices, as a matter of fact not at all with most of them. 8.1 fixed the issue with that for me. I would like to see an update to the camera. I have a Lumia 950 and that is the best camera that there is for photos. I am hoping the Nokai 8 will camera will get updated. Or at least maybe the Nokia 9 will have a very good camera.
I had switched from Windows system to Android system.
Waited for many months for Nokia to launch phone with Zeiss lens, and finally I purchased Nokia 8 also due to this feature, which is already on my Lumia 730.
In Lumia 730 the camera is producing decent images.
HMD/Nokia kindly update the validated camera app as going through the forums I have found users are eagerly waiting for this updation for Nokia 8.
