Question about Camera quality on snapchat?
the glass on the back of the latest iPhone has much better quality than a Samsung camera
That's normal. Most apps' cameras are not as good as the main iOS stock camera app. Down to things like resolution. So its usually recommended to use the stock camera app & import images to whatever app you need to, if you really care about the quality that much.

Snapchat compresses the image to save data.
