As more and more people use Vista, some old methods of accessing a mobile phone's webcam that worked under XP may not be applicable to Vista. Today, taking the N73 phone as an example, we will show you how to use the N73 as a webcam for QQ under the Vista system, saving a bit of money. I definitely want to share this experience with everyone, hoping it will be helpful to you. In order to help new users, I will try to make the process as detailed as possible.
