I love that this whole thing was a non-fix to a non-issue. The fix didn’t change any signal strength issues. It just changed the UI a bit.

A cosmetic fix to a cosmetic issue. Still a fix and still an issue :) Some might even say UX is more important than the underlying tech!

philipallstar•4mo ago

Only if you define UX as including all the really hard stuff that goes into engineering the device, and not just the externalities. A car that looks nice but doesn't go isn't as important as a car that goes but doesn't look nice.

cut3•4mo ago

of course, why wouldnt you intclude all the experience

philipallstar•4mo ago

Because the people doing UX are generally just UI people who want to claim credit for all the hard stuff as well. So they have no ability to change any of the experience other than redesigning the cosmetics.

jebarker•4mo ago

I remember this episode but not the details. Why was it a non-issue if holding the phone did cause the signal strength to drop? Is it just the case that the drop was too small to affect call quality/stability?

danhau•4mo ago

I don‘t remember it at all, but based on the post it sounds like it was just a UI quirk that made the signal loss look much worse than it really was.

I‘m guessing gripping any phone will drop signal strength, but the iPhone made itself look worse.

lern_too_spel•4mo ago

That's exactly the opposite of what the post says. It says that holding the phone wrong caused the signal strength to drop precipitously, but the UI still showed that the signal was strong.

danhau•4mo ago

Ok, then I guess Apple changed the UI to more reflect reality?

jml7c5•4mo ago

No, it was a real hardware issue, too. Applying a thin layer of kapton tape would reduce the drop by 8 dB.

This wasn't a non issue. You touched the phone in the wrong places and you would drop off an existing call.

Most people solved this by indeed not "holding it wrong" or getting cases (I don't know if the cases worked, but there was a whole industry built around advertising cases that solved this problem).

jerlam•4mo ago

Apple's interim fix was to give all the owners a case.

pipe01•4mo ago

AFAIK the cases worked because they prevented the hand from making electrical contact with the metal parts

Steve Jobs solves iPhone 4 reception problems: 'don't hold it that way'

That's weird, "don't hold it that way" is 22 bytes, not 20 bytes.

Apple changed the antenna design in the iPhone 4 Verizon variant, and in the 4S to really resolve the issue.

That fixed the actual problem in hardware - the software fix just made things look better.

jerlam•4mo ago

It probably didn't help that AT&T service was poor during this time, as they were the only iPhone carrier in the US, their backend was quite unreliable as everyone was discovering streaming video.

All my iPhones, not just the 4, regularly dropped calls with AT&T until I switched to Verizon.

> the software fix just made things look better

The software fix made things look worse. The "bug" was that the number of bars was misleadingly high.

willidiots•4mo ago

To TFA's point - "Bars" are relative and relatively meaningless - [SS]RSRP, RSRQ and SINR are your real numeric signal strength / quality measurements.

Not sure about Apple, but on Android, individual carriers can set the number-to-bars thresholds. Two otherwise-identical signals could be represented as a different number of bars depending on your particular carrier: https://source.android.com/docs/core/connect/signal-strength

addicted•4mo ago

There are 2 problems to this.

1. I seriously doubt Apple was accidentally displaying more bars on the phone. If it was a "bars" issue then it was almost certainly done deliberately to make the iPhone reception look better than what it was.

2. It wasn't just bars. I had this phone and you would literally drop off calls by holding the phone differently when you hadn't done anything else. There was a genuine problem with the phone that I don't think was ever resolved other than people getting used to holding the phone differently like Steve Jobs told us to.

I lost my iPhone and switched to a hand me down from my parents which was a generation older and the service was significantly better.

Author of this thread here, thanks for sharing! This was the first time I publicly went into assembly code so I was a little nervous about screwing up a detail but glad it’s getting a warm reception.
