Digital Trends - If you’ve ever cursed at your mobile operator for providing less-than-stellar service—or no service at all—wherever you happen to be at every instant of every day…you’re not alone. A new survey commissioned by Empirix (and conducted by Harris Interactive) finds that fully 86 percent of U.S. smartphone users experienced problems tapping into multimedia application on their mobile devices, with three quarters of U.S. smartphone owners report having connectivity problems while trying to perform other smartphone activities like Internet searches, downloading data, using apps or social networking services, or accessing media. Furthermore, 20 percent of U.S. and German smartphone users reported “always” or “often” having problems using data-related smartphone functions, with that percentage increasing to 30 percent in the United Kingdom.
