I bought the QD a year and 2 mths ago. The phone has crashed twice, and the operating system still feels unstable. Its a funny feeling using the phone, especially if the usage is on the higher side, since the phone log constantly fails and the DTMF for automated response dialling fails to work. I have to constantly switch on and off the phone to reboot it!
I liked the look of the product at initial stages, but soon found that it is extremely user-unfriendly in terms of usage and taking calls. The phone is also on the heavier side, and hence taking long calls is also an issue.
I am very disappointed with this one Nokia product. I think that the Operating System needs significant improvement and far more stability. Nokia has always been my perferred choice given the user friendliness and standard features of the phone, but it really doesnt seem so in this case!!!
