I bought Nokia 3230 in March 2005 for around 12, 400/- and since that day it keeps hanging while receiving calls, playing games and listening to mp3 songs.Some times after removing MMC and replacing is again it requires reboot hence the concept of hot swap is foolish in this model. The mobile become badly slow even with 256MB MMC.
Batter back is poor and reception quality is not so good. FM and MP3 sound quality is poor than Rs5000 mobile phones. Sound is not clearly audible with the inbuilt speaker and more over it is Mono hence cannot enjoy stereo track without headset.
Camera quality and screen resolution is not so good. Keys are hard to play racing games and if playing with joy stick there are chances of breaking.
Had lots of issues while connecting phone to the PC and also its operating system easily gets affected by viruses and phone stops working abruptly.
