Apple on Antenna Issues
This letter was signed “Apple”, not “Steve”. Funny how that works, and concerning that AT&T’s network may be even worse in some places than we’ve been led to believe all this time. But hey, as long as the bars get taller, we’re in good shape.
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.
We are [adopting AT&T’s formula and] also making bars 1, 2 and 3 a bit taller so they will be easier to see.
