Everyone are into smartphones these days.GOne are the days of phones like Nokia 1100.Phones are used for more than making/recieving calls and sms.I have a few frnds who have been using phones since 1997 and who own either an iphine/BB/android now.They say the call quality was more better in the regular phones.they mean to say that in available signal if a smart phone is head to head against a normal phone ,the normal phone would deliver a better effeciency.Just wanted to know if an of our own wizards here felt that way..frankly speaking i dont agree with their opinion,but i dont own a smartphone.Please throw some light with ur own observations here.
