100% - The handset has most likely been opened up and messed around with and as you said once it starts to give trouble, it will always give trouble. Bottom line is the phone was 2 weeks old, not 2 years or even 2 months. I am going to insist on a new handset. I will never be happy with that phone knowing full well it is trouble. I guarantee it would be a matter of weeks before I have to send the darn thing back for something else.
