I had a problem with the N8 from the first day I bought it, it just switches off and then ON with a blank white screen.
and recently when it does that It's difficult to switch it on again. I press the power button for about 8s and it vibrates three times, but when I switch it on again it shows the white screen. I've been trying to switch the phone on for about 30 minutes and its irritating. I really wish I could change this phone. It has also become really slow with all the games i've installed. I am not impressed at all.
@fisika, Have you installed any theme recently? If so then the theme might be unsupported.
Try removing your memory card if the theme is installed in memory card.
i hold the power button but it only shows the white screen and turns off with the mwnu button still lighting.. how'd you turn on the phone??? plsss help
