I brought Nokia 101 mobile phone 12 days ago. It is GSM phone with dual sim card facility. It has mp3 player with upto 16 GB micro SD support. My problem is my phone is restarted automatically after few minute. I took phone at Nokia service center and they flash firmware and give it back to me. After 1 day I notice same problem in my phone. I donít understand what the problem is because after flashing same problem is occurred. I talk to my retailer about this problem and ask him to replace the handset but he refuse to do these. Anyone know what problem is this and how to solve it?
