One of my side volume key is not functioning.. Cannot increase the volume of the phone.. Search through the web but cannot find any solution..
Anyone have any idea how to fix it ?

Press harder for many times but it still doesnt work.. Only one key..

Maybe is something to do with the hardware.. Will send to a shop and have a check..

Thanks for the comments..

I have having a rather large problem with my N85. Whenever I try to make a call or answer one, the phone shuts off. I know my service is still good as my SIM card works in other phones, I have tried a factory reset, a hard reset, and reinstalling the software several times and none of it fixed the problem. I didn't drop on it on sit on it or anything like that. It started happening while I was using the phone as a USB modem for my computer, but all of my resets should have fixed it if that was the problem. Any ideas or just straight to Nokia repair?

*Update: I was just able to make a call, but my phone shut off the instant I hung up...odd. Texting still works too as well as the net.
