Same issue here. Can't belive 512GB version has 8GB RAM and still having such an issue. I always have over 3GB RAM available. I was told to clear Camera data but it's only 188KB and how could it affect the camera performance?
Just recently moved from iPhone and this is a really major disappointment as camera is the most used function for me.
I only seem to have a lag issue with my front facing camera. It usually takes pictures immediately, but the framerate is really slow which leads to a lot of my pictures being blurry. The only way I can get it to focus somewhat decently is to hold my phone extremely still for about 4-5 seconds. But even after that it doesn't seem to take as clear of pictures when it rarely works properly.
Can't believe there is still no fix. Been wanting to upgrade my s9plus to note 9 512gb for the extra space, but now starting to look like I will have to go to another phone. The 64gb storage on the s9 is killing me always running out of space. Hopefully they wont make the same mistake with the s10.
Wondering if the silver and black versions of the note 9 have the same problem?? do they also use the sony sensor in the US?
