View Full Version : iPhone 4 Antenna Problem is Caused By a Design Flaw

I don't think this is going to be fixed by a firmware update...

but rather a piece of masking tape. :thumbup:

Apparently this was predicted by an antenna engineer somewhere in europe prior to release.
Also apparently Apple will be releasing an update that will somewhat minimize the issue or at least thats the rumor

they should just give everyone some invisible shield type thing or a silicone glove thing. that should get rid of the issue.

BGR appears to have nabbed a document being distributed by Apple corporate to AppleCare reps tasked with handling iPhone 4 customers miffed with the antenna performance fiasco -- and for the time being, the recommendations are focusing on managing expectations, not fixing the problem. In a nutshell, reps are being instructed to pass on a more politically correct version of Steve's email by telling customers that they should "avoid covering the black strip in the lower-left corner of the metal band." Interestingly, they agree that bumpers might fix the problem, but they're emphatic in saying that they "ARE NOT appeasing customers with free bumpers – DON'T promise a free bumper to customers." And yes, that statement is complete with caps and bold in the source document, so they mean business, it would seem. If it's any consolation, Apple says that "the iPhone 4's wireless performance is the best [they] have ever shipped," but let's be honest: for those zapping their calls into the afterlife every time they brush their phone the wrong way, it's not much consolation at all.
freakin annoying company..

When this story first started making the rounds, I was shaking my head a bit as people were reporting on the "number of bars" being shown. What was driving me even more crazy is how people would say "my 3GS gets 3 bars, and my iPhone 4 gets 1" (every phone displays bars differently).
It looks like some of the Anandtech guys decided to drill down into this issue a little more than most, and found a way to get the iPhone 4 to display actual signal strength (in dB). By doing so, they discovered a few interesting things:
- Cupping the phone tightly resulted in up to a 24dB signal drop (with 20dB being an average for gripping the wrong part of the phone)
- The amount of signal represented by the bars is logarithmic; the difference between 1 bar and 2 bars is much smaller than from 4 to 5 bars. For those who said they never saw their signal indicator budge from 5 bars when gripping the phone, that's why. 5 bars means a signal between -91 and -51dB.
- While there is less attenuation, both the iPhone 3GS and the Google Nexus One do suffer from it depending on how the device is held. Again, this is using actual signal numbers, rather than bars.
- On a good note, the iPhone 4 IS better at maintaining a weak signal than the iPhone 3GS.
You can read more from this page from the Anandtech Article (http://www.anandtech.com/show/3794/the-iphone-4-review/2).
So yes, Apple's planned software update will probably just tweak how much signal is represented by the bars (to "hide" the problem). The only real solution is the bumpers or some sort of insulative coating as the Anandtech editors suggest.

it's funny now they're saying it's software and they're changing the antenna rating to conform to standard practice...
i guess falsely making your phone look like it has more reception than it actually does is a bad thing... lol.
