Worked for me. Though unable to save rich capture, video does not go above 1080p. However it is tons faster at loading.
One thing I did notice, is that in the photos app, when you are looking at the picture there is no quick edit in the app it was taken. Like when I take a picture with the classic app, it says, open with lumia camera classic. This is no longer there, just edit options with the pencil icon.
Interesting... I found it worse when I zoomed in as it was pixilated but the normal camera zooms in better. Maybe its because I don't have denim installed. I don't have the option for 4K recording but it says pics are now 16MP but I can't see the difference myself when I done a comparison test
Ignore my last comment. It finally fixed itself after taking a pic. It can now zoom in with less pixilation. I really like this now. Should I take a pic in pure 16MP or 16MP+J-PEG? bear in mind I wont be using it on my laptop.. Just looking at pics from my phone
