Re: Search button backlight

You need to take tour device in for service.

Hey, did you solve your problem?

I have the exact same issue with my Lumia 930...
What I have noticed is that sometimes it has backlight and after some time - it doesn't... When I press aroud with my fingers (applying a little bit more force than my usual) the back light turns on for a while (sometimes) which makes me think it is a hardware issue.
Could someone who knows what is going on help us here? I really don't want to give it for repairs because that automatically means no phone for 30 days (at least where I am from) and if it's a software issue I can live with that for now but if it's hardware - I would need to live with no phone for a while...
