Hello, I have not used my Note PRO 12.2 for almost year as I switched to iPhone. Now, I need to use it again due to its large screen size and S-Pen. When I quickly scrolled through the photos in the Camera app, I saw grid of grey boxes and they were slowly replaced by the photos/videos I took. Is there a way to speed up the preview? If so, will the increased performance be noticeable? I am using a SanDisk Ultra 64GB Micro S XC I card. Thanks
