This is the new letter from Apple about the issue of it’s dropping calls and how you grip the phone.
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.
So, this basically means that the software in iPhone which shows the bars has been faking it and showing additional bars which can be interpreted as good signal strength. And this lead to so much confusion among iPhone users – because their calls dropped even when there were more bars – putting the blame on AT&T.
All the 3 generations of iPhone have been basically cheating people when it comes to showing signal strength. If Apple is stunned by this, then what about the users?
