Apple: no reception problems, only an error in the display of the notches

iPhone 4 incorrectly calculates the number of bars displayed to signal the availability of the field: Cupertino is working on a software update that will solve the problem not only in iPhone 4 but also in iPhone 3GS and iPhone 3G. The explanation of the problem that is rumbling on sites dedicated to technology and not only finally arrives from Apple through an open letter addressed to all iPhone 4 users.

In the letter Cupertino declares to have returned to the test bench to test and verify the behavior of the iPhone 4 we are aware of the fact that most users and reviews claim that iPhone 4 offers better reception than the iPhone 3GS, while at the same time a large number of users write to us saying to lose 4 or five notches when I tighten the phone to cover the black strip in the lower left corner of the metal band. This is a drop far below normal and as a consequence of this iPhone has been accuased to have a constructive defect. According to what is read in the letter, the Apple engineers went to work discovering the real (says the message) reasons for the problem: we were shocked to learn – continues the letter – that the formula we use to calculate the way in which bars represent the totally wrong signal strength. For example iPhone 4 displays 4 bars when instead it should display only 2 ″. For this reason "Users who observe a fall of several bars when holding iPhone in a certain way are very likely to be in an area with a weak signal, but they cannot know it because we mistakenly display 4 or 5 bars". Apple reiterates that a slight loss of signal occurs not only for iPhone 4 but for any other phone that is held when the hand goes to cover or touch the antenna.

In the case of iPhone 4, the imprecise system of calculation and display of the bars has worried many users who notice a transition from the full field with 4 or 5 bars to 1 or even zero. "The sharp drop in bars – explains Apple – primarily due to the fact that the full field was not real". Cupertino announces that it is already working on the software update that will solve the problem not only in iPhone 4 but also in iPhone 3G and iPhone 3GS which use the same calculation and display system of the bars. The new procedure being implemented will follow the guidelines and calculation formulas for displaying the bars proposed by AT&T.

At the end of the letter, Apple reiterates that iPhone 4 offers better network performance than all previous iPhones, and finally apologizes to users. "For the vast majority of users who have not been bothered by this problem, the software update will only make the bars more accurate – finally addressing those who instead were more worried – For those who have had problems, we apologize for any anxiety that we may have caused. "

That the open letter from Apple and its apologies can really silence the controversy seems rather doubtful.

A large number of users, in fact, report sufficient reception to make a call and a persistent line when they do not touch the bar but the total disappearance of the signal when they put their hand in the wrong place by touching the antennas that are exposed and almost impossible not to disturb seen the design of the iPhone. It seems to be possible to conclude that their different arrangement, high or low that is the quality of the signal coming from the tower, would benefit the stability of the reception.

On the other hand, at least in our experience, the fact that if true that iPhone 4 in ideal conditions (not always easy to reproduce) has a better signal reception than iPhone 3G and 3GS, it is equally true that when the line is never there managed in no way to cause it to fall simply by touching a corner of the old models, where we are systematically able to do it with an iPhone 4.
