Dear iPhone users 4
The launch of the iPhone 4 was the launch of the most successful product in Apple's history. The iPhone 4 was considered by critics worldwide as the best smartphone ever created and users have told us how much they appreciated it. Therefore we were surprised to read reports indicating problems of reception and we immediately decided to investigate this matter. Here's what we learned.
To begin, simply take a mobile phone in a certain way is likely to reduce the reception of one or more bars. This applies to the iPhone 4, iPhone 3G, as well as many phones Droid, Nokia and RIM. But some users have reported that the iPhone 4 lost up to 4 or 5 bars when he was given by covering the thin black band located in the lower left corner of the metal strip. This decrease is much larger than normal and, therefore, some have accused the iPhone 4 to present a design flaw in the antenna.
At the same time, we continue to read articles and receive hundreds of emails from users indicating that the reception of the iPhone 4 is better than the iPhone 3G. They say they are delighted. And it confirms our own experience and our tests. So why all this?
We have discovered the cause of this significant loss of rods: it is both simple and surprising.
During our investigation, we realized with horror that the formula we use to calculate the number of bars of signal strength to be displayed is completely wrong. In many cases, our formula incorrectly displays two bars longer than it should for a given signal strength. For example, we show four bars, so that sometimes we should display in two. It is very likely that users noting a decline of more bars when they hold their iPhone in a sense, is indeed located in an area of weak signal strength, but they are unaware because we wrongly displaying four or five bars. The decrease in the number of bars, therefore, comes from the fact that the number of bars displayed at the start is not realistic.
To remedy this, we are adopting the formula recommended recently by AT & T to calculate the number of bars to display for a given signal strength. The intensity of the signal remains the same, but the bars of the iPhone will now report a much more accurate, which will provide users a much better indication of the level of reception they will receive in a given location. We will also enlarge slightly bars 1, 2 and 3, to make them more visible.
We publish in a few weeks a free software update that will integrate the formula and corrected. Because this error is present since the first iPhone, this software update will be available for the iPhone 3G and 3G.
We went back to the lab and have everything re-tested. The results are identical: the wireless performance of the iPhone 4 are the best we have ever issued. For the vast majority of users who have not been bothered by this problem, this software update will only make the display more accurate bars. To all those who have been affected, we extend our apologies for any inconvenience this problem has caused.
Reminder: If you are not completely satisfied, you can return your iPhone not damaged in any Apple Store or return it to the Apple Store online within 30 days from the date of purchase and benefit from a full refund.
We hope you enjoy as much as we iPhone 4.
We appreciate your patience and your support.
