Two patterns here contradict each other:
- This thread is relatively small with 21 pages compared to 267 about the battery problem. Even a thread about factory unlocking has twice as many pages as this one.
- Yet, most of us with the Echo issue have experienced the same issue with the replacement phones.
Statistically, there's something very wrong here. A small percentage of customers are reporting this issue, yet almost all of those that do get replacement phones with the exact same problem.
In other words, if this particular hardware/software issue is so wide-spread that most replacement phones also have the same problem, then this should be a much bigger problem amongst customers! ... this thread would have been 5-10 times longer.
I'll admit not all customers use their wired headphones extensively but surely 30-40% would have noticed by now. It's also easy to imagine that support staff are told not to admit the scale of an issue to customers, but what if this really isn't such a common complaint?
The only environmental constant seems to be the headphones themselves. However, I've experienced the issue myself even when using an 2 year old pair that's never given any problems on my 3GS for two years.
Maybe we have faulty headphones that are actually damaging the headsets on first use. It would explain why the replacement handsets have the same issue ... because the headphones aren't replaced at the same time. Once the handset is damaged, the problem also occurs with other headphones.
Has any of you been given a replacement handset that DOESN'T have this issue ... even when using the original headphones supplied with the faulty handset?
