That would be everyone. Is there anyone who actually LIKES the FPS placement? No one that I have ever talked to.
We can put up with it perhaps, smudge the camera lens when we miss touching it 10 times a day, have trouble reaching it because it is so far up on the back, and maybe even get used to it there.
But it's a mistake, it's in a terrible location, people don't like it, and they are saying so. It's something people do (unlocking their phones) dozens of time a day. So for something you don't like, that is a lot of uses over the lifetime of a phone to have to deal with. If you are OK with it, that's cool of course ..
