Apple opens up about iPhone 4 reception problems

Following complaint after complaint regarding the iPhone 4’s reception issues, Apple has finally opened up and started giving some real answers. It turns out it is a software issue.

Rather than placing the blame on the fourth-gen iPhone’s exterior antenna design, Apple is offering up an unexpected explanation: the signal bars don’t accurately reflect signal strength.

Upon investigation, we were stunned to find that the formula we use to calculate how many bars of signal strength to display is totally wrong. Our formula, in many instances, mistakenly displays 2 more bars than it should for a given signal strength. For example, we sometimes display 4 bars when we should be displaying as few as 2 bars. Users observing a drop of several bars when they grip their iPhone in a certain way are most likely in an area with very weak signal strength, but they don’t know it because we are erroneously displaying 4 or 5 bars. Their big drop in bars is because their high bars were never real in the first place.

A software update will be issued “within a few weeks,” so for many of you still waiting for your iPhone 4 to arrive (or you’re still in line outside your local Apple or AT&T location), this might not even trouble you.

Does this mean that users can go back to holding the iPhone 4 with their left hands? It should, although Apple still asserts that “gripping almost any mobile phone in certain ways will reduce its reception by 1 or more bars.” This might be true, but that doesn’t excuse the error in the first place.

    @FADS_z InFomercial Marketing at it's finest: I mean this reasoning is like telling people that bought a new car, that oh we severely managed to under calculate the vehicles actual speed for all these years. So when you see that you're doing 20mph, you're actually exceeding 50mph speed limit. So we've recalculated it so you think you're going faster than you really are! ....psssst don't believe it when you drop a call. It's either a figment of your imagination or the other person's service provider! ....aren't we just sooooo.... special?

  • Not just reception problem, but perception problems plague Apple
    @i2fun@...

    There are connectivity issues with most phones, but most makers (a) don't put it where you would want to hold it; (b) don't charge as much as an iPhone; (c) don't deny it publicly by the CEO in terse notes which is just asking for trouble.

    Perception is that Apple views itself as always right and customers as the source of the problem.

    Here is a great "jab at Jobs" and at other infamous CEOs article if anyone is interested:

  • Fascinating is a word I use for the unexpected.
    In this case, I should think "interesting" would suffice.

    It is allways interesting to watch the Apple loyalists defend Apple's defects due to inadequate engineering and testing on another entity.

    And, apparently, tech issues. Case in point, the supposed iPhone 4 receptions issues, which, from an engineering perspective, is a non-issue. One does not need to be an Apple loyalist to see this, or to understand that Apple's antenna design is superior to the standard internal antenna for any number of reasons.
    This is NOT a case of inadequate engineering, it is case of the media manufacturing a tempest in a tea pot.

    And no, I do not have an iPhone, or an iPod, and have no intention at this time of getting either.

    I still don't think they are being honest. I have had real dropped calls in areas where my 3GS worked fine. I get full bars on my iPad 3G and my old 3GS when I walk outside, but I get dropped calls while outside calling AT&T about my fluctuating signal strength.

    I can just see you now, walking around outside with all the Apple products dangling from you trying to test reception. Sure glad I don't have that problem with my Android, no dropped call ever.

    Android phones don't have a perfect batting record here either; the G1 has been plagued with WiFi unreliability problems for a long time. The customer service staff at T-Mobile tried to blame it all on customer's overcharging their batteries!

    But it should be obvious by now: the iPhone4 problem is a hardware problem. Something is wrong with the design of the antenna and the antenna system's ground.

    Now they may be able to compensate for the flaw somewhat with a software patch, but a real fix would have to be in hardware.

    I would have to agree.

    This is a hardware issue that Apple has tried to mask with a software visual patch back with the 3G and 3GS. The design for the 4 antenna just exacerbates the signal issue to the point the software "fix" cannot longer mask it.

    This is just the first shot from Apple knowing they have an issue and trying to d_r_a_w_ this out to minimize sale impact and hoping that consumer "memory" - notoriosly a short one; will gloss past this.

  • Design Flaw in Their Rush to Make it Beautiful Rather Than of Functional!
    @stewball_z I think something had to have driven them to go against the grain and design the antenna so different that they're not admitting it's a coverup. I think they tried to design around some Antenna and 3G patents they're being sued on. Nokia has at least 1 lawsuit based on antenna circuits or software patent!

    Afterall who in their right mind designs an external dipole antenna that you have to grip to hold it? Lemon Phone!!!

    @i2fun@... ok, sure, no on wants an external antenna... so 1990s. But how about dual antennas, diversity if not full MIMO. Like, oh I dunno, those in smartphones in devices from real radio and cellphone companies. You have to wonder about the first, maybe even the second such device from a PC/PMP company like Apple. But they NEVER have managed to get an iPhone that works nearly as well as a phone as any old "free" Nokia soap-bar phone. And it's not as if Apple lacks the cash to hire a real RF guy for this.

    I really expected, after three fails, they'd have made the iPhone 4 one of the best actual phones out there. But now there are people even claiming it's worse than the 3GS. My Droid might not be as "sexy" to some as the iPhone 4, but it has never dropped a call. That's not just Verizon here, Motorola knows their RF.... in some of their designs, that's all they got right.

    And sure, you can claim voice is so 1980s... but the same antenna(s) is/are used for data.

    "btw... they could no doubt throw 100 or so patents at Apple and win 50 of them and kill them easily."

    Care to name some of these patents, or are you just going to spout meaningless generalities with no citation or backup, as is your wont?

    " But unlike Apple they just aren't into the whole idea that you have to kill your competition to survive"

    You seem to know as little about Nokia as you know about China. Nokia's history in patent courts is, shall we say, prolific.

    Your ignorance is particularly amusing considering Nokia firing the first shot in the patent war:
