On my new LG fangs I can nod read the front control panel. The screen is too dark to see the letters clearly. Is there a way to have the control panel lighted?

You cannot adjust the brightness of the control panel on the LG LSEL6335F. The control panel does not have a backlight, which makes it difficult to see the functions, especially in low light.
