A big issue hits every iPhone 4 owner this period: signal strength. Most of the experts(except Apple ones) claim that this is caused by the magnetic band. How this happens? We’ll give you some proofs.
Reports say that when you hold iPhone 4 in your left hand, you will experience signal loss problem. On the left side of the phone is a little space in the magnetic band and when this is covered the strength of the signal is weakened or lost.
Further more, a conversation between an Apple user and Steve Jobs was these days discussed and featured all over the Internet. The user told Steve that Apple should be ashamed by the signal performance of iPhone 4. Users mock about it, saying that it’s impossible to make a call without dropping. Steve replied arrogantly, telling the user to “calm down”, “relax”, this is happening only in weak signal areas and Apple is working to solve this small issue soon.
Last week, Apple released a letter explaining that this is just a software problem and will be fixed with a coming update.
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.
To fix this, we are adopting AT&T’s recently recommended formula for calculating how many bars to display for a given signal strength. The real signal strength remains the same, but the iPhone’s bars will report it far more accurately, providing users a much better indication of the reception they will get in a given area. We are also making bars 1, 2 and 3 a bit taller so they will be easier to see.
We will issue a free software update within a few weeks that incorporates the corrected formula. Since this mistake has been present since the original iPhone, this software update will also be available for the iPhone 3GS and iPhone 3G.
Here is a video from Youtube where you can see a demonstration of this signal issue during calls.
More than this, it seams that Apple wants to hire Antenna engineers. Here is the proof:
In the end is clearly that Apple have an antenna issue with iPhone 4, but the problem is they want to cover this into a software issue. We will continue to follow this subject and we expect Apple to solve it soon.
Apple Jobs, Apple
