It's hard to say what the problem might be or even if it's related to software or hardware.
Let's start with a battery pull. If it's a software problem, the battery pull should resolve it. Remove your battery while your phone is powered on then replace it. Please note that if it's related to a hardware issue, we'll be unable to help you here. You would then have to call Etisalat for resolution.
Let us know if that helps you.
