Message: Hello,

I saw your review on samsung i640v and it was very helpful. I am no starting to experience some problems with my phone so I decided to send you an email asking for some help. I am using a vodafone version in Bulgaria it is completely unlicked, and it constantly looses sound. Sometimes I can dial numbers and there is sound on the phone and sometimes it losses it. I used your reset codes and it was ok for a day or two then it started again. Some help will be much appreciated.

Solve:I think its a hardware problem.But you can reset your phone for last try.If you have warranty then go to customer care center.
