Problem After ICS 4.0.4 update .............

[#1]

After 4.0.4 update, a big problem appeared...

whenever the screen is ON, and i leave it idle till the light fades, then it goes OFF.
if i press ANY key instantly after it goes OFF, it goes back ON ... that does not happen

, it turns back ON to a BLANK BLACK screen

no whatever i do it stays BLACK...

PS>

i'm not an average user, i have 3 other android phones >>>
