I noticed my screen has multiple vertical lines especially when displaying a grey picture. The lines are very small but noticeable if you look at your screen very closely. Is this normal for OLED screen? Easiest way to test is hold down the power button until the grey screen comes up. I can see the lines on my PSV

I'm having some screen issues with my PSV. I notice several vertical lines on the screen when displaying grey/brownish colors. The lines disappear when displaying black/white/bright colors. Here is an image taken from my phone. You can see a line especially in the middle. Can anyone try changing their background image to the default brown and see if they also having the same problem???

So you're saying your PSV also got the same problem? I did some google search on other devices with OLED screen apparently the Galaxy Nexus (which uses the same type of screen) has the same problem when displaying grey images. Just want to know if this is a common problem or just my unit is retarded >_>

Have you tried restarting your system? Is it wifi or 3G version??

Maybe try , restore to default settings?
