Nokia has so many classic and best models. N-gage QD is a one of them. It has so many facilities but it has some small problems also like its Size & weight is first problem. It is too much heavy not easy to pick up it any where. Another is its battery problem it’s battery backup is very low and it’s memory card problem is also main. It has its different type of memory card. Nokia cell phones have same memory card we can use easily one to another but N-gage QD don’t allow this. Some others are its software problems like sound card problems, video gallery, Bluetooth & Hardware problem like rubber problem, screen problems etc. So we can say that Nokia N-gage QD has some problems.
