Last year, Apple launched the iPhone 4 on the market and very soon it was subject to a series of criticisms due to problems with signal loss when the bottom left part of the device was covered with a hand. Apple found two solutions for this problem: mounting a Bumper case and changing the algorithm that calculates the signal strength. Apple then claimed that the algorithm for calculating the signal strength was wrong in iOS 4 and that is why users complain about the fact that the signal is easily lost so that in iOS 4.0.1 it implemented a new system for calculating the signal strength.
..Apple's design of the [Signal Strength Meter] drastically and surreptitiously inflated reporting of excellent reception and under-reported instances of poorer reception,” the complaint states. "The Meter thus conveniently promoted a positive, if not euphoric customer reaction to the iPhone, which inures to Apple's benefit at the expense of Plaintiff and other purchasers.
Now it looks like that formula for calculating signal strength it is used in an American court against the Apple company. A man filed a lawsuit in which he claims that the formula designed by Apple displays more signal bars than it should, giving users the impression that the device has a stronger signal than it actually has. The man who sued Apple is not asking the company to solve problems with the formula that calculates the signal strength, but is asking for damages because an iPhone with such a problem cannot be resold at a good price.
The idea behind the process is bad, but maybe through its media coverage, Apple will solve the problem.
