I contacted samsung on the camera issue with snapchat, of it being too zoomed in. They said it is not a phone issue but an app issue. Snapchat itself does not use its camera through your phone, it uses its own camera. Snapchat needs to update and fix the camera issue on these bigger phones. Not only samsung phones have this problem but also the iphone xr has the same problem. Snapchat needs to adapt its camera functions with the bigger screen phones. I emailed snapchat already ...no response yet... best we can do is keep reporting the issue to snapchat on their contact email or other contacts..
