According to the findings of a new survey by the Pew Internet & American Life Project, majority of cellphone users still experience the most infuriating problem linked to mobile handsets --- dropped calls.

Going by the statistics shared by Pew in its "Mobile Phone Problems" report, as many as 72 percent respondents in the survey said that they still experience dropped calls occasionally; with as many as 12 percent of the cellphone users saying that they experience the problem at least once every day, and 32 percent revealing that they suffer dropped calls several times a week.

Other than highlighting the fact that dropped calls still continue to frustrate cellphone users no end, the Pew report - authored by Pew Internet Project researchers Jan Lauren Boyles and Lee Rainie - also revealed that, among the other annoying things faced by the users include unwanted marketing or sales communications and slow download speeds.

While 69 percent of the survey respondents said that they receive unwanted marketing communication occasionally; 25 percent said that it happened a few times every week. So far as download speeds are concerned, over two-third of the 55 percent cellphone users who use their handset for accessing the Internet said that they were hit with "slow download speeds."

Nonetheless, noting that cellphone users are fast getting accustomed to the immediacy their devices provide, Boyles said: "As mobile owners become fond of just-in-time access to others and as their expectations about getting real-time information rise, they depend on the cell phone's technical reliability."
