For context, back in 2010 when the iPhone 4 came out, people noticed you could grip the phone in a certain way and the signal bars would plummet from 5 to, like, 2. A few weeks later, they published a letter (https://www.apple.com/newsroom/2010/07/02Letter-from-Apple-Regarding-iPhone-4/) admitting fault, blaming a bad formula. The letter was shared around and clowned upon (https://daringfireball.net/2010/07/translation_iphone_4) but nobody really looked into what the formula between 4.0 and the patch in 4.0.1 I was a stupid eight-year-old at the time, but now I’m a stupid adult with access to a disassembler.

@samhenrigold@hachyderm.io don’t forget the free bumper (or not holding it wrong)

@samhenrigold@hachyderm.io so we have to deal with people taking speaker calls in public while holding their phones "that" way to this day... not even because there was any practical drop in reception, but because the UI was not deceiving enough? 😵💫

@samhenrigold@hachyderm.io Very interesting, nice work. The fix actually makes sense from a user perspective. The thresholds should be different according to technology (GSM, 3G, and today 4G, 5G). -122 dBm does not make sense for a GSM phone when sensitivity should be around -104 or 108 dBm. For instance, -99 dBm for 5 bars in GSM is wrong. -80 dBm is correct. Even for 3G or CDMA the new values are better representation for the user.

@samhenrigold@hachyderm.io I just watched this video yesterday. In combination with your thread, it seems that "Antennagate" was actually a combination of hardware and software issues. https://youtu.be/RppnQ28BsiE
