Reception Woes, Screen Discoloration, Glass Issues Plague iPhone 4

Despite an outpouring of rave reviews for the iPhone 4, a number of issues including problems with reception, discolored screens and easily breakable glass may give some would-be owners pause.

You waited in line fourteen hours. Committed to another two years with AT&T. Charged the $300 on your MasterCard. Now the iPhone 4 is finally yours.

But you didn’t plan on actually using that magnificent chunk of metal and glass, did you?

As it turns out, Apple’s next Wunderphone might actually work a lot better on the pedestals in Apple stores than in real life. According to a flood of first-hand reports from new owners, merely holding the metal band around the iPhone 4 can cause signal to plummet, the bottom of the screen often suffers from inexplicable yellow blotches, and the tough “Gorilla Glass” that Apple talked so highly of isn’t nearly as resilient as the company claims.

In the first of many videos documenting the most severe problem, one new iPhone user shows his phone sitting pretty with four bars of signal, until he picks it up and wraps his fingers around the metal band, at which point it drops to zero. Setting it down, they zoom back to where they were.

An isolated incident, the iPhone faithful will insist. But Gizmodo’s call for reader confirmation yielded well over a dozen responses – many with video or pictures – of the same issue.

Touching both the left and bottom sides of the case seems to be causing the drop, and cases seem to prevent it, suggesting the problem comes from bridging electrical connections with the hand, and not RF interference from it.

Other users report yellow discoloration at the bottom of their screens, and in some cases, whitish dots. Although less commonly reported than the reception issue, a number of high-resolution images of the problem on several different phones seem to suggest there’s something to the claim.

Finally, a number of unlucky folks who have already tested the phone’s durability through accidents report extremely fragile glass that has scratched easily or broken from allegedly minor drops.

So far, Apple has yet to make any official statement on any of the issues, although one Gizmodo reader with reception issues claims Apple tech support told him to “get a bumper.”

  2. Rick Mcp at 11:43pm 6th August 2010 I've had an AT&T tilt (HTC), swapped it out for an HTC FUZE and finally went to the iphone. Why? Because i could NEVER, NEVER, NEVER use those HTC phones on the internet. They just didn't work. It would take forever to connect and then it would stay connected for about 2 minutes and after loading one or two pages it would drop out. I have probably spent close to $1000 on phones before the iphone. The Iphone was the very first phone i purchased that did what it said it would do. Straight out of the box. Same with the iphone 4. I love it. Does it live up to all the hype? Not in my book. The facetime is neat, but seriously??? When are you both around wifi and want to video chat? Travelling and in a hotel maybe. Put facetime over 3g and I'll be impressed. I hope it's coming. But overall, I'd take the iphone 4 over any other phone on the market (and I've seen a few of the androids, incredilbes, etc here at work).
  3. Rick Mcp. at 11:43pm 6th August 2010 I have the iphone 4. One of the lucky ones that preordered and got it a day before launch. I love it. Signal loss??? yes, I tested it once I read all the stories. I saw it with my own eyes, the signal did just what people are saying. The other problems? Haven't seen them. Iphone or HTC???
  4. Paul Johnson at 3:42pm 11th July 2010 My guess is that this is people who are trying to drive and text anyhow....who doesn't run with some tricked out cover for their cool new toy? I have NEVER had an issue with the screen glass strength. If you are a gorilla and cannot handle something without banging it on the ground and on everything around you....get your knuckles off the ground and stand upright....it is the year 2010!
  5. Alex at 1:24am 10th July 2010 Load of rubbish about the signal, I'm holding one right now and I just tried holding my phone like that video and not even one bar dropped, and who holds their phone like that anyway, looks like a Vulcan death grip or something, these people just have nothing better to do, and as for the glass I bet that happened through miss treatment or stupidity, great phone, glad I own one :)
  6. 카라멜 커피 at 11:48pm 26th June 2010 I guess I'm one of the few who doesnt have the problems and is enjoying their new iPhone 4? Still, I hope they get these issues sorted out.
  7. Roboto at 4:05pm 25th June 2010 If this were any Microsoft product you would see an entirely different response from the media and the online 'user' community. I guess there are more Apple share holders out there then I had estimated. Apple is growing to be as big as Microsoft and with that comes the unavoidable glitches and challenges a company faces when they are truly mass producing products. This is not surprising. What is surprising is the undying customer loyalty Apple enjoys no matter what issues their latest product exhibits. Again, if Microsoft or even LG for that matter had to tell their customers to hold a device a certain way for it to function, Steve Balmer would be tar'd and feathered and LG would be under investigation by the federal government much like a modern day John DeLorean. All I can say is well done Steve Jobs, you like PT Barnum have once again proved - there is a sucker born every minute.

  9. mikegem at 4:52am 25th June 2010 The reception issues are not a surprise. The iPhone 4 has three antennas. These are slots, or spatial discontinuities in the metal band around the phone. It's been known for a long time that empty spaces in a conductor (aka, "slots") can radiate RF signals and receive them just the same as the more traditional metallic antenna elements. However - if you cover up a slot antenna with an electrical conductor and/or a lossy dielectric material, the radiated RF will be either reflected back to the transmitter (if covered by a good conductor) or absorbed by the covering material (if the material is "lossy" or absorbent in the RF sense). The human body is both electrically conductive (full of ionic liquids, or electrolytes) and RF-lossy (called a high loss tangent, which is part of what makes microwaves able to heat stuff). So when you put your hand over the slot antennas of your iPhone 4, you absorb outgoing transmitted RF and you block incoming RF signals. And this is consistent with the observation reported by many that a case helps alleviate the problem. Most cases are nonconductive and are non-lossy, or RF-transparent. So they create a small gap between the slot antenna and your hand through which outgoing and incoming RF signals can pass. This is pretty basic, simple stuff for RF design engineers. Anybody who designs phones for a living w/should have spotted this.
    1. jade at 11:15am 3rd July 2010 I'm not an RF design engineer, but I would go for this explaination. Apple people must consider a solution for this, instead of just suggesting the use of bumper case.
    2. D2Einc at 4:03pm 27th December 2010 I have worked with electronics for most of my life. And to top it all, I just bought an iPhone 4 today. Despite what some people have to say about the "Lack of signal" that the new antenna design might get, when it works at it's full potential, it's signal strength can easily dwarf many other styles of phones. Many AT&T stores even recommend that when you buy the iPhone 4 that you buy a "bumper" for it, not only because of the signal issues, but because of the fact that the metal band on the phone can cause minor electrical damage to the internal components if anything acidic or chemically toxic gets into the gaps of the antennas (usually transfered from your hands). There are alot of reasons to get a bumper case: to eliminate hand to phone transfers, the signal issue, to help the phone grip on an uneven surface (the glass back helps it to slide effortlessly), and at times just because it looks good to some people. It's not always a bad thing to end up having to buy an accessory for your phone, especially when it's not exactly like it is going to break your account. We will be getting all of the eventual updates, same as everyone else, then most everyone will be on a level playing field. Besides, every phone on the market has it's own particular problems when it is first released, especially if it is modeled for the most part after it's prototype. If you are going to buy a phone for the perks, then you must also be prepared for it's faults.
  10. Mike at 6:44pm 24th June 2010 We're holding one right now and we don't get a signal loss even when wrapping our hands around it. Obviously, we're not going to test the glass, but, duh, buy a shell. Screen looks money. We'll keep testing, but so far, we can reproduce the signal loss shown in this video.
    1. ianbell330 at 6:46pm 24th June 2010 Can you post a video on YouTube and link? I just read that its the iOS 4 not the new iPhone 4 that is the problem, and that people with older phones and the new OS are reporting signal loss.
  11. @JerrickChew at 5:47pm 24th June 2010 HTC desire :)
    1. asdf at 10:15pm 25th June 2010 HTC Desire..... how long before this one becomes outdated? 2 more months maybe?
      1. Sub at 11:17am 29th June 2010 It will become outdated just as fast as the Iphone4.
  12. @JerrickChew at 5:43pm 24th June 2010 Paying so much for all this? Over-rated once again... Yawns... So much for the hype
    1. ianbell330 at 5:46pm 24th June 2010 So which phone do you have? Just curious....
  13. ianbell330 at 5:27pm 24th June 2010 No matter how in-depth Apple's testing is, consumers will always find the real problems in a product. The reception issue is a big deal, the rest sounds like isolated cases.
    1. mike at 7:15pm 5th July 2010 The reception problem really isnt that big of an issue. For a brand new phone, complete redesign of anything out in the market, it is a very easy fix. People just need to suck up the fact that they have the 'firsts' of the phone and buy a case/ bumper for it.
