Apple Plans Update for iPhone Signal Strength Glitch
|
Apple Inc. said all of its iPhones, including its new iPhone 4, mistakenly inflate readings of their cellular signal strength, an uncharacteristic stumble for the consumer electronics giant.
The Cupertino, Calif., company said Friday in an open letter to iPhone 4 owners posted on its website that it had been using an incorrect method to determine the number of bars of cellular signal strength it displays on its devices. In several instances, iPhones mistakenly show better cellular reception than exists, the company said.
"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," the company wrote. Apple said the problem has been present since the original iPhone.
The investigation into the issue was touched off by user dissatisfaction over the iPhone 4's antenna. Adding that "gripping almost any mobile phone in certain ways will reduce its reception by 1 or more bars," Apple said iPhone 4 users appeared to be seeing a bigger drop than normal in antenna reception when they held their phones in a certain way because they were in low-reception areas to begin with. Apple said it would make a software update available to fix the bar display problem for the iPhone 4, iPhone 3GS and iPhone 3G within a few weeks.
