I purchased a nokia handset 3110, just 2 days back. I dnt know what’s the problem with its speaker. Smtimes even if the volume is increased to full I am not able to listen to the next person.i m sure there is no problem of network. I also went to nokia care they suggested me to replace the set. Then I went to the dealer from whom I purchased the set. First of all his behaviour was very rude and he said me to come next day.m not sure whether he will change my handset or not… what should I do??
