Snapchat Design Improvement Idea

A little Snapchat improvement idea:

I was trying to point out some current Snapchat design fails I personally don't like and when I was playing around with the new background I just asked myself: What about to use phone's camera as app background? It can be turned on the whole time so I can just place the content on it for the other screens like conversations, contacts or settings.

There is just lower opacity and blur on it so if there is very bright background the content will be still visible. But personally every time I browse Snapchat I'm actually holding my phone in one hand and walking so the phone's camera is pointing to the ground.
