This has absolutely nothing to do with bugs on the site or forum. Moved.

Send it back to the manufacturer to get it fixed. Has it come in any contact with water? Because if it did, you're supposed to wait about 4-5 days before turning it back on, so it can dry. Do it before then, the circuit will fry.

if its been in water or anything else its likely to be a little corroded. Sometimes rinsing it out with meths and sticking it in the hot water cupboard overnight will clear it up. If not it may be a software/firmware fault in the phone (i know my erricson W950i had that problem once) just take it back to where you bought it from and ask them.
