Toll to operate the GoPro 4 black

Toll to operate the GoPro 4 from behind, especially since the front display is very small and with the nested menu a bit strange to use. Attached are different cover for the normal and the divers housing with different water densities, with and without touch function. The time until the display is automatically turns off set. Off the LCD should also not consume more battery. However, what is annoying, is pulling the activation of the touch function after switching through and keep a red dot on the display. Unfortunately, I could find no option to disable it.
