According to a report from a Spanish newspaper, Nokia just announced a cell phone research which lasted for four years that the character of human can be analyzed by the habits of people to use cell phone. This research suggests that the missed calls in women's cell phones are more than that in men's, because the habits of women to use cell phones are different from men's. Usually, men like to put their cell phones in the right trouser pocket, and can answer the calling by feeling there are vibrations. Therefore, taking out the cell phone to answer the calling is only a thing for men to spend several seconds. Instead, 61% of women are used to putting their cell phones in handbags, and pay no attention to it at most cases, and even do not know whether the cell phone rings. Although some women hear the calling in time, they often can’t find it before the call is hung up.

Also, according to the cell phone research report, there is an age difference in cell phone using habit. If you are used to carrying the cell phone at the waist, you will probably is a mature men. Besides, the habits can be different due to the different states and cities. In Tokyo, people often change a cell phone only in a few months, and only 3% of people get used to using a cell-phone case. However, Koreans are used to taking care cell phones carefully.
