Hi everybody

Whenever I use the power save mode on my nokia 6230i (v 3.50) and the digital clock screensaver appears, the display will be messed up after some time: it will show some black and white stripes, as it does for a brief moment when you turn it on (the waiting interval for this to happen seems to be random). I have to switch off the phone and turn it back on to get a normal display. Now I have power save mode off, but I would like to use it normally
Is this a known issue? Or do I have a faulty phone?
I would really appreciate some help on this. Thanks!
