Many have been excited about the release of the iPhone 4, only to find that their phone drops several signal bars when gripping the phone by the lower left-hand corner.
Apple replied to these complaints by stating that the formula they use to calculate how many bars of signal strength to display is totally wrong. Their formula, in many instances, mistakenly displays two more bars than it should for a given signal strength.
The company also stated that gripping any mobile phone will result in some loss of intensity of its antenna performance, with certain places being worse than others depending on the placement of the antennas.
The solution to this? Easy! Apple says to simply hold the phone a different way, and use an iPhone case or cover, which in most cases will restore some signal strength to the phone. Other suggestions have included: resetting the phone, resetting network settings, removing the SIM card and re-placing it, docking the phone or attaching a USB cable and attaching scotch tape to the SIM card hence applying more pressure.
Whilst this problem was prevalent in the US and the UK, surprisingly on the whole Australian users have found no such problems. One reporter from The Advertiser tested the phone out and found he could only reduce the signal bars by one or two at the most. He tested it with a number of SIM cards around various locations and still the antenna problem did not surface.
What this means is that in Australia you have greater freedome in selecting an iPhone 4 case of your liking with little or no risk of experiencing signal issues.
