But there was also a question of degree. It's clear that different users experience the problem to different degrees. It's not so clear why that's the case.
Some explanations: Let's say we have a signal strength between 0 and 100, and the phone works properly if the strength is 50 or better. If you are in an area with signal strength 51, then the slightest signal loss will stop it from working. If you are in an area with signal string 95, then nothing can stop it. So if your home has signal strength 51, you will be complaining like mad, but if your home has signal strength 90, you won't see what the problem is.
One thing Apple did was changing the display for signal strength. Let's say it used to be 100 = 5 bars, 90 = 4 bars, ..., 50 = 0 bars (stops working). If your strength went from 5 bars to 4 bars, you complained. Now they show 60 = 5 bars, 58 = 4 bars, ..., 52 = 1 bar, 50 = 0 bars. If your strength went from 95 to 85, it still shows 5 bars. No complaints anymore.
And then it is very likely that the signal loss depended on how you held it. If a hand blocks the signal, then I would expect that people with big hands suffer more than people with small hands. And I think that most people want their phone to work, so if holding it one way stops it from working, they would hold it another way; instinctively without even noticing. Other people who want to find faults would do the exact opposite.
