I went into the Kingston (UK) Apple store yesterday, tried all their display iPhones and not one showed the problem of signal degradation.

Hmm, is this just a problem with production units and not display/review units?

There are four people (including me) who have iPhone 4 here where I work in Swindon and none of us have this issue.

If anything the signal is better on this than the 3GS. I am loving it, best thing yet.

Would you say, maybe, that it was "hysterical?"
Not sure what you mean, regardless it seems like this issue isn't affecting everyone, but enough users to draw attention from Apple. Let's hope Jobs is right, and that there is no issue.

No problem here but I'd be pissed if it happened to me. Apple needs to give out 1.7 million bumpers (ain't gonna happen).

This has got to be the worst poll ever... Really? What do you hope to learn by this?

You probably could get a job with the Global Warming people.... :p

For me, the problem is location sensitive. When I'm at school, I can't reproduce the problem... at home it happens every time. (I start out at 5 bars in both places) I have no idea why this would be, but the results have been consistent over two days now.

For what it's worth, in 12 years of owning cell phones (9 years Verizon, 3 AT&T), regardless of the phone, sometimes you see a good signal, try to make a call, and you got nothin'. Sure, a signal indicator is nice, but the only thing that really matters: will my call go through and not disconnect?

A signal indicator, in my 12 years of experience, has never been able to reliably answer that question. Yeah, it's gonna affect the liklihood, but sometimes cell service just don't work, and the indicator, regardless of what it shows, won't change that.

So, I would think the better question is: does holding iPhone 4 in a certain way reliably prevent calls from connecting or cause them to drop?

Its on now, I love Family Guy.

anyway, at work today London Lloyds TSB, the fat girl in black with the 'I've just been laid all sleepy voice' who has an IP4 but doesn't know how to adjust the volume...well I picked her phone up with my left hand and sure enough the bars started dropping!...my 3g in the same position, rock solid 5 bars, like its on viagra...

"giggitygig!"

Ok how many of you here actually have had your iphone4 signal degraded till "NO SERVICE" when held in that "way"?

And how many of you came to ur own conclusion after viewing the video from gizmodo...


the truth is, you probably lose 1 or 2 bars that's ALL. and it will return back to normal after a few seconds.. it's very normal.


The video you guys seen has been put up by some guys with their own selfish agenda... u guys heard of a device that distort signal? use frequently at theaters and cinemas to prevent phones from getting signals.

trust me... it's a NON ISSUE.

I've never seen the Gizmodo video, and I noticed it because it would and will drop any call I was on if I picked up the phone at home, something no previous iPhone has done before. The dropping bars are there, yes, but they are a symptom of the problem, not the problem itself.

ok bob.. i am making a wild guess here.. you are probably the unlucky one.. i think u got a lemon... and it has nothing to do with the way u hold ur iphone or the exposed antenna design thingie.

No it very much is the exposed antenna - cover it with electrical tape and the problem goes away.

Just got an reply email from steve jobs about it.... he said "You don't need a case. The iPhone 4 works just fine." I have tried submitting it but I have never done it before.... Mar or may not have done it right.

Well if you are serious than we're screwed - if Jobs won't admit the problem its not going to get fixed.

Anyplace where I get 3 bars or less of cellular signal with the cell phone untouched. Subtract more than 3 bars in a barely sweaty "grip of death" and I get the no service message.

There are several places near me where I get less than 3 bars. Heck, there are (or used to be?) places near Apple's Infinite Loop HQ where I only got 3 bars of 3G last year. They could have tested by taking some short walks in nice sunny CA weather.

And 5 bars could mean anywhere from barely 5 bars to getting a signal more than 10,000 times stronger than needed for 5 bars (40 dBm higher signal power), so it's real hard to tell (even if the signal drops out even by a factor of 1000X) in strong signal areas when your cell phone is showing 5 bars.

nop you are wrong I love my iphone and hop that it will work good I realy want to keep it.
but when I open the phone it start with 3 to 4 bars as I put it in my hand it start to loos the bars until no service.
sorry I wish it was not the case.

oh one more think this is happning in my home, and bythe way my blackberry bold 9000 has full 5 bars at the same rome no mater haw I am holding it.

This is a software issue. iPhone 3GS with iOS 4.0 has the same issue.
Strange i don't have the issue with iOS4 on my 3GS, Swisscom Provider, but i must say, while my iPhone 3GS is almost 1 year old,i do see a boost in battery power over iOS3, i mean my battery lasts longer on iOS4...

yes, remember when you had to remember to exit certain programs before turning off the screen or when you'd come back the battery would be significantly drained? Now with iOS 4 that doesn't happened. Left my GPS program as the forward program when I left the car yesterday - went to use the iPhone 30 minutes later and the battery was still saying 100% with the GPS sitting there still open.

When I hold the phone comfortably in my left hand, I experience signal loss when I am at home in Queens, but no problems when I am at work in Manhattan.

I think the reason this is affecting some people and not others is not a case of location, but a case of the person using it. I get signal loss on my UK iPhone 4 so I went back to the store and they had no idea what I was on about, they said their demo phone was fine. I try their demo phone, signal gone within 30 seconds. The store manager then went on to try my one I'd been experiencing the issue with, nothing happened.

I think this is caused dependant on how conductive you happen to be, does anyone scientific have any idea if humans can be more or less conductive than one another?

My thoughts exactly. I highly doubt that the issue is related to location, inconsistencies in the hardware, or even variations in static electricity from person to person like some have suggested. I think Kuro is exactly right (sorry if this has already been discussed somewhere else). I'm a biomedical/electrical engineer and I deal with this type of electrical interface all the time. There are HUGE variations in skin conductivity from person to person. For example, if a person has dry, calloused skin, their skin is likely to be a far worse conductor than someone with soft, moist skin and should cause less of a problem. There are many, many variables that would have an effect on the conductivity, so it's not at all surprising that the problem seems intermittent.

In addition, the human body is an excellent conductor of any kind of electrical noise. I'm no antenna expert, but to have such a direct electrical connection between the phone antenna and such a noisy source seems silly.

I'm curious to see if the problem caused by bridging the two antennae is lessened by turning off all other radios (wifi, bluetooth, GPS). I would think that would at least help to eliminate some interference.

It seems like more of a hardware problem to me, but it will be interesting to see if Apple can work some magic and come up with a quick software fix. I hope they do, because I'm holding off on getting mine until this is resolved...
