Unit 1 Assignment 3 Reliability Apple’s ( AAPL ) iPhone isn’t just the best-selling smartphone in the world , it’s also the most reliable. A new study conducted by the company behind the community based trouble-shooting resource FixYa on Friday issued its latest smartphone reliability study. The study used data from 722,558 combined problem reports combined with market share data from Stat Counter to assign a reliability score to leading smartphone vendor.

The iPhone, for instance, uses 24 times as much spectrum as an old-fashioned cell phone, and the iPad uses 122 times as much, according to the Federal FCC.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
