On my 9550 goodle maps 4.0.2 works well except one issue that seems small but is quite annoying if you use google maps for routing, etc.. Before (3.2.1) whenever you were moving, the back light stayed on by design. Now (for me) the backlight goes off and stays off, even while I have it plugged in to my charger or if I press the blue dot to "recalibrate" My location. I'm still running 5.0.0.320 (due to a compatibility issue with the RSA SecureID software). Is anybody else seeing this problem, is there a fix?
