Verizon iPhone Also Haunted By the Death Grip 191

Posted by samzenpus from the here-we-go-again dept.
adeelarshad82 writes "Turns out that the Verizon iPhone 4 is also plagued with the same problem as the AT&T version, the 'Death Grip.' This isn't completely surprising since Apple has made no significant changes in the antenna design to warrant a permanent fix. As a result, the 'Death grip' causes a drop in 3G data performance as well as the Wi-Fi performance. What's strange is that the Death Grip gives inconsistent results which is why analysts don't view this as a big problem for Apple, chalking up the news as 'bloggers looking for something to write about.' Analysts also argue that Apple sold millions of AT&T iPhone 4's last year and despite the media-furor, consumers did not line up at Apple Stores demanding refunds."

    You know, there's a saying about doing the same thing over and expecting a different result...

    • The only ones who were expecting different results were the bloggers who just happen to be people you can type really really loudly on the internwebs.

      For most people it didn't matter as they were covered or had decent coverage by AT&T. Personally I find it more telling that Verizon has plans to throttle heavy user before launch. While I don't expect a big difference in service it just might happen in a few markets.

        My workplace bought iPhone 4's for everyone who needed to be on call. When I first got mine, I tried to duplicate the issue and wasn't able to. Neither were my co-workers. Completely covering the phone antenna with my hands may have resulted in a one bar drop. We have O.K. AT&T coverage, but not great. This was much ado about nothing.

        • you do realize they updated the way the phone calculates the number of bars displayed. Many experts noted that its difficult to actually measure the phone's actual reception, since its impossible to know if the phone is lying to you or not.

          Try it whilst on a call in an area where reception isn't strong...if the call drops, then the issue remains.

          It applies to most phones, but the iphone 4 seems to be affected more easily, due to the antenna placement.

          In any case, it is not the first phone to use big bits of the casing as an antenna. A lot of Nokia E series use the battery cover as an antenna so if your hands are wet you can see similar drops as well.

          Both have had to use bumpers on their phones to be able to use them as and when they want.

      The CDMA iPhone actually does have an antenna change, which most of these "OMG VERIZON DEATH GRIP IPHONE" hacks are ignoring. There are two antennas (as is standard in CDMA), one on each side of the phone. To block most of these (and actually drop a call) you have to squeeze pretty hard (and possibly put the phone in a lead box). Getting the bars to decrease and getting a call to end are two entirely different things.

        Two antennas aren't going to solve the death grip, and CDMA antennas are not much different than 3G/GSM antennas. (And the iPhone always had two antenna halves, one on either side). Antenna length is almost always dictated by frequency in use, and the CDMA bands are pretty close to the 3G bands such that the same antennas can be used for both.

        Death grip was caused by human fingers bridging a gap between the 3G antenna and the WIFI antenna, and it could happen with a single finger touching the gap. No actual "Grip" required. The problem was solved with free bumpers, and users learning to avoid touching the gap. See this wired article: http://www.wired.com/gadgetlab/2010/07/iphone-its-the-antenna-stupid/ [wired.com]

        Apple pushed the myth of the death grip, to try to divert attention from their design flaw. It was never about the grip. It was only about bridging that gap. The free bumpers eliminated the problem.

        If the Verizon phones lack that gap, then any signal decrease caused by holding it is the same as you see on any other cell phone but don't confuse that the antennagate on the original iphone 4.

        • I thought all this was very well known up front. I read articles months ago about how they did not address the "death grip" issue at all. And according to what I read, the ONLY changes made were a CDMA specific antenna and corresponding chipset/drivers. Assuming that's true, how could anyone possibly be surprised that the same issue persists. After all, I've not read anything which supports Apple even attempted to remediate the issue.

          Its basically the same 'ol device with the same 'ol flaws.

            It would be commercial suicide to fix the death grip problem because it would mean admitting that it exists. Apple's official line is that there is no problem, but as a gesture of goodwill they gave everyone a free rubber bumper anyway.

            If a 4.1 version came out with a fix all existing customers would have a legitimate argument for getting a free upgrade. Not sure about the US but in the UK design defects have to be put right for the typical lifetime of the product, which for a phone is 5 or 6 years.

        • Bridging the gap with your finger partially detunes the antenna; since your skin is not a perfect conductor, the charge carriers moving in the antenna effectively go through a "tunnelling" effect at the gap. This is probablistic in nature, meaning that a proportion of such carriers will continue to behave as though the antenna was at its normal length. What you would see by analysing the received frequencies is that the normal frequencies would be diminished but not obliterated when the gap is bridged. I

        • Correct, the "death grip" everyone is confused with is present on nearly all handsets... It's only the short-circuit due to the external antennas on the original iPhone4 that was new.

          And the actual deathgrip issue (without the short circuit) is actually quite mild on the iPhone 4, as far as I can tell. The only people doing better in that department are Motorola (couldn't get my old Milestone to drop further than 2dB, no matter how I held it), while HTC are more or less the worst offenders (My Desire's sign

        • Thanks for buying into Apples marketing, yes you are correct al phones will drop signal when you block most of it in a "Death Grip". You don't need to actually hold an iPhone 4 to cause this problem, because Apple placed the wifi and phone antenna's on the outside you can bridge them with your little finger.

        OS X Lion is introducing full screen apps for the first time on OS X, where the entire UI changes (ie, Dock goes away, top menu bar goes away) so it the app that is full screen has full focus. I expect then the green button will do that (perhaps as a toggle - small, large, fullscreen).

That doesn't mean it can't also have flaws (hello, Finder, hello dotfile littering on non-Mac filesystems, hello eternal loop of drive-spin-up-spin-down if you insert an unreadable DVD, among other things).

      It's not just branding, Apple in general makes stuff of very high quality and with a lot of effort in usability design. I've used many computers, laptops, mp3 players and mobile phones over the years. I bought and iPod in 2005, a Macbook Pro in 2007 and an iPhone in 2009. Before that my exposure to Apple had been limited to a couple of times at an aunt who owned one for DTP work. I have used nearly all flavours of Windows and Linux, over 50 different mobile phones (job related), over a dozen PDAs (Palm, WinCE PocketPC, WinMob). Only some stuff from IBM (now Lenovo) comes close in build quality.

      I'm not saying it never breaks or doesn't have design flaws sometimes, but in general it's a joy to use Apple products. The interfaces are very intuitive, consistent and a real effort has been made to minimize the effort you have to do to get to your goal. Sometimes at the expense of choice and features. The best example is still that when the iMac came out, it had just USB and Firewire, no Serial or Parallel ports, PS/2 or floppy drive. At the time they were laughed at, peripherals would never use USB and the floppy was essential. I think time proved that they were right.

      Since I started buying Apple, my "gadget hunger" has greatly diminished. The only thing I am considering is an iPad and I since bought a NAS for backup purposes. None of the other things I used to look at hold any interest to me any more, it just doesn't compete. The Apple stuff might be a bit on the expensive side, but because it has high end specs when new, they last very long, especially because Apple keeps providing software updates. My 4 year old Macbook is still fine, it's only got updated to OSX 10.6 from 10.4 for 29 euros. All the updates to my iPhone 3GS have been free. Between those two devices there isn't a single thing that I can't do, but want to do.

      I know that I'm sounding a bit like a fanboy, and maybe I am, but that's especially because I have used so many other devices from other manufacturers and none have given me as few reasons to want to throw it out the window as the Apple products I have.

  • I read the headline and thread summary to this story and the next thing I know I wake up with keycap impressions on my forehead and a puddle of drool on my wrist rest.

    This story is a powerful sedative! I'm bookmarking this baby!

  • I bought a new phone last November. At first, when my old contract was winding down, I was looking forward to getting an iphone. But after all the bad press, I decided to go with an android.

    Apple may have sold millions of iPhone 4s. But, maybe, Apple could have sold millions more?

  • Who in the hell uses a iphone to make phone calls anyhow? I have been carrying mine for nearly three years and have enjoyed every minute of it. If it where not for the fact that I need a older device to test my software on I would have gladly upgraded already. I have never had any call problems and I would not hesitate for a single second to buy the new one.

  • I still have /. on my RSS feeds because sometimes they link to some interesting scientific & engineering subjects. Once in a while, like today, I dive into the comments just to see how things are coming along (when extremely bored I've even left a comment). But it's still the same. Utterly childish, like 4th grade boys on the playground duking it out over who has the loudest mouth. Step back and look it over. See yourself?
