    Apple blames faulty formula for iPhone 4 problems

    In response to mounting reports that the iPhone 4 offers subpar call reception, Apple Inc. today said that an algorithm used in its new smartphone is flawed and promised to update its iOS 4 operating system in the next few weeks.

    Users called the company's inaccurate algorithm explanation "hooey" and worse on Apple's support forum.

    Apple blamed the faulty formula for problems users have encountered with the iPhone's signal strength, which has been said to quickly plummet when the phone is held in certain ways.

    "We were stunned to find that the formula we use to calculate how many bars of signal strength to display is totally wrong," Apple said in a statement issued Friday morning. "Our formula, in many instances, mistakenly displays two more bars than it should for a given signal strength. For example, we sometimes display four bars when we should be displaying as few as two bars."


    Essentially, Apple said that the bogus indicator misleads iPhone 4 users into thinking they have a stronger signal than they really do, and then when they hold their phones in certain ways, the signal diminishes quickly and unexpectedly.

    "Users observing a drop of several bars when they grip their iPhone in a certain way are most likely in an area with very weak signal strength, but they don't know it because we are erroneously displaying four or five bars. Their big drop in bars is because their high bars were never real in the first place," the statement continued.

    Apple said it would issue a software update that will replace the flawed algorithm in a "few weeks." The defective formula has been part of the iPhone's firmware since the original 2007 iPhone, Apple said, so the fix will also apply to the older iPhone 3G and 3GS.

    Complaints about call and data signal-strength problems in the new iPhone 4 surfaced within hours of the smartphone's launch last week. By the next day, Apple was acknowledging that holding the iPhone 4 can diminish the signal but offered only generic advice, telling users to "avoid gripping it in the lower left corner" or "use one of the many available cases."

    Apple's explanation today didn't address reports by many users that the iPhone 4 dropped calls when they held it a certain way.

    On Apple's support forum, most people were skeptical that the upcoming software fix would really solve the problems they have with their iPhones.
