I purchased 9320 in Nov’12 worked well for first 10 months but after that the ringer stopped working suddenly. The service point here in Goa sent the handset to Bangalore for repairs under warranty.
It came back after 15 days (repaired ok). After that again after 6 months ( a month ago)suddenly the net stopped working. I went to Vodafone (as my connection is Voda).
They tried hard to resolve the issue at their end but could not. After that again they sent it to Bangalore by service point & now it has not yet come back after 1 month also.
