So I have something similar(I have an iphone 8, not a 7, but same camera). I found one that worked somewhat(it doesn't work great https://www.amazon.com/V-8-Protector-Tempered-Protection-Modified/dp/B08127THXF/ref=sr_1_8?keywords=fake+camera+iphone+7+to+11&qid=1580351743&sr=8-8). What I did with it was I got an iPhone 11 Pro case from tumblecases.com(I really think they make beautiful cases) and then I put it on. However, I will say that it didn't work great with camera(looked a little off, but I don't really use camera so much so don't care) .
