Phone camera advances fast, not the phone flashlight


I think the flashlight on mobile phone is not as useful as compact camera. They have following disavantage if taking people photo

- too close to the lense: you almost look at the flash when taking photo, and hence it hurts your eyes.

- the flash is slow, much light comes to your eyes and hence hurt your eyes again.

- flash is strong to hurt your eyes but weak to brighten object.

why do they put the flash closed to the lense? Why there's almost no improvement on flash function of the phone.

I prefer the flash could position away from the lense, better if it is pop-up flash.
