iPhone 4 Hell: A Personal Tale of iPhone 4 Woes
Apple's unprecedented move to hold a press conference regarding the iPhone 4's antenna issues underscores the power of the masses--and the fact that the phone has serious problems. I know about the iPhone 4's flaws firsthand. Here's what went wrong with mine.

As I write this, I'm on my third iPhone 4 replacement so far. Yes, that means I've had a total of four phones in the three weeks the phone has been on the market. As responsive and friendly as the folks at the Apple Store have been through this, I really didn't need to get to know them so well. At this point, I've spent as much on cab fares to and from the Apple Store as I would have on a couple of bumpers in different colors.

I could write off one bad phone as a fluke--but three is extreme, and indicates that something more may be in play. I've come to expect better from a company like Apple. I reached out to Apple for a comment, but I've received no response at this writing.

Consumer complaints about the iPhone 4 include poor reception, dropped calls, a faulty proximity sensor, software crashes, and more. With Consumer Reports' widely publicized withdrawal of its support for the iPhone 4 earlier this week, the clamor reached a fever pitch: Consumers wanted Apple to do something more tangible than simply blame its software for mistakenly calculating signal strength and announce a software update to fix how the signal-strength bars display.

I experienced some of the oddities on my very first phone call: During the call, the touchscreen kept activating when I didn't expect it. This problem inadvertently invoked the iPhone 4 video-call feature, FaceTime. Little did I know that it would be a regular occurrence over the next month. My first iPhone 4 also froze up several times, with the touchscreen failing to respond.

Replacement Time

The next day, the San Francisco Apple Store cheerfully swapped the device out for a fresh, shrink-wrapped model. And I lived with that phone and its wonky behavior for the next three weeks. I eventually cried uncle and scheduled an appointment with the Genius Bar.

This iPhone 4's symptoms were many, even though I never synced the phone with iTunes and I purposefully downloaded only a handful of apps (ESPN FIFA World Cup, Scrabble, eBay, Pandora, Hulu Plus, and AIM). First off, the proximity sensor--which detects your face's location vis-à-vis the touchscreen--made cheek-dialing the norm. The sensor simply would not behave, and one time it even let my cheek create a new contact on my phone.

Other oddities persisted; for instance, one photo refused to transfer to my PC due to an error detected in the phone, and the alarm clock scheduled itself. I also had plenty of failed calls, none of which I could directly attribute to the so-called death grip, even though my phone, like others, showed the bars dropping when I held it just so. But what pushed me to action was the repeated crashing of the mission-critical phone app.

Immediately, the Genius Bar doctor was able to detect that the proximity sensor had a problem, noting that it "lagged" when she tested it. That lagging behavior could account for the improper screen activations, the tech added, noting that she had seen more phones come back with a proximity-sensor issue than for any dropped calls due to the well-publicized antenna design problem.

Proximity-Sensor Problems

When I asked the tech what could cause this, she said it could be due to the sensor's cable not being seated properly. Another possibility: a faulty sensor part.

That was the first acknowledgment I'd heard about the proximity-sensor problem, let alone a potential explanation. And either possibility, I was told, was grounds for my getting another replacement phone. However, when the tech ran Apple's Behavior Scan diagnostic software, we learned even more about my phone's wonky behavior.

Among the 219 phone calls I made with this handset, I had 20 modem resets. The tech told me that a modem reset explains the failed or dropped calls, as the signal gets lost during the reset. While that alone was not a red flag, the tech noted that was an unusually high number of resets.

To elaborate, the iPhone 4 has an Infineon chipset that serves as the cellular voice and data chipset for all 2G and 3G service. "If in fact that device is resetting," says Ken Biba, chief technology officer of Novarum, a 3G and 4G wireless design and testing consultancy, "it would cause a dropped call. And if it needs to be reset, that suggests it is not performing well in some manner." Biba further notes that with the iPhone 3GS, Apple was aggressively managing power consumption, and in the past the Infineon chipset might have been a factor on the dropped calls in some markets with AT&T. Whether that's the case with the iPhone 4 remains to be seen.

On my iPhone 4, I also experienced low memory, which the tech told me was directly responsible for my phone app's freezing up. Hearing the low-memory diagnosis was odd, considering that I had opened only 22 apps at some point or another, and those apps were still accessible in the multitasking pop-up for fast app switching. Sound like a lot? I had installed just six apps, in contrast to the dozens that most iPhone users have. The only app that truly ran in the background, perhaps, was Pandora--which I'd made a point of manually closing out of earlier in the week--so I'm not sure it's a suspect to consider for the phone app's freezing up.

That the diagnosis called out the number of apps was odd unto itself. At WWDC, I had heard that there was no limit to the number of apps, and that iOS 4 would manage the apps for the user, purging apps before the device would run out of memory. Presumably, that would include purging apps before the device reached a low enough level of memory to crash basic applications like the phone app, right? Oops, apparently not.
