Did the Note9 camera quality improve after the Pie one ui update?
photo/video quality? no. but you will notice a new layout...
I've had the note 9 before the update and I must say it's a solid phone and I loved the 1 st update and the updates to the camera including night mode
I'm on T-mobile and the September security/software update improved the image quality of pictures taken with the stock night mode camera. It now performs better than the GCam port.
