I am using nokia 3110 c cell phone since last one year. Every feature of it is working fine. But I am experiencing one problem in this. that Vibrator is not working in the phone. Whenever I keep my cell phone on vibration mode nothing happens it remains silent without any vibration.I tried different profile and reset factory settings and other option as well but none of them worked .Can anyone help me in this? whether it is software or hardware problem?
