Mobile phone companies

Dear mobile phone companies,

you're improving your phones all the time.
You're giving us more graphic power, more CPU power, more battery power.
I am very grateful for all these features.
But now, I have found something which would make a bigger difference than the enhancements listed above.
I don't know if you've already seen it. But there is some sort of rear view cameras for BMW cars, so you can park safely.

That's what it looks like.
I want the same thing, but not for parking. I want to have a background on my mobile phone that's always visible, showing me what the camera sees when I'm using it.
So why do I want that?
I want it, because it looks so damn stupid to walk into cars / street signs / dogs / excrements of dogs / people just because you were using your phone to text someone.

This would make the big difference.

Pretty pretty pretty please with cream on top.
