LG VX-8600 / AX-8600
Set the outer display
You can keep the outer display on all the time if you want (taken from the VX 8100 forum).
Open the phone. Press OK. Press 0 (zero). The screen will display service code. Enter six 0's (six zeros). In the service menu, choose 2--Field tests. Scroll down to A (power save mode). Choose OFF.
This will keep the outer screen on all the time. I have no idea what it will do to battery life. I also don't know if it changes the settings for the inside screen.
I haven't the guts to play with all of the other menu functions, but if you do, post what you learn.
