Apple PR : iPhone 4 reception issue is a software problem, solution is coming in few weeks

by admin on July 2, 2010

Apple just issued a communication on the problems of antenna iPhone 4. Officially, Apple attributes the problem to an error in the baseband code that calculates the exact number of bars. Specifically, the iPhone 4 shows two bars above the display of the signal than it should. Apple will soon release an upgrade for the iPhone 3G, iPhone 3GS and iPhone 4 will correct the problem based on the formula of AT & T.iphone-4

Upon investigation, we were stunned to find that the formula we use to calculate how many bars of signal strength to display is totally wrong. Our formula, in many instances, mistakenly displays 2 more bars than it should for a given signal strength. For example, we sometimes display 4 bars when we should be displaying as few as 2 bars. 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 4 or 5 bars. Their big drop in bars is because their high bars were never real in the first place.

To fix this, we are adopting AT & T’s recently recommended formula for calculating how many bars to display for a given signal strength. The real signal strength remains the same, but the iPhone’s bars will report it far more accurately, providing users a much better indication of the reception they will get in a given area. We are also making bars 1, 2 and 3 a bit taller so they will be easier to see.

We will issue a free software update within a few weeks that incorporates the corrected formula. Since this mistake has been present since the original iPhone, this software update will also be available for the iPhone 3GS and iPhone 3G.
