我有两个Android手机：nexus s和t-mobile g2。我刚买了一套有内置麦克风的新耳机。 Nexus S似乎识别音频输入，但T-Mobile G2没有。这是一个硬件限制还是因为我在我的G2和Icecream三明治上运行了Android 2.3.6？
I have two Android phones: a Nexus S and a T-mobile G2. I just bought a new set of headphones that have a built-in microphone. The Nexus S seems to recognize audio input but the T-mobile G2 does not. Is it a hardware limitation or because I am running Android 2.3.6 on my G2 and Icecream Sandwich on my Nexus S?
Most likely it's a difference in the TRRS layout of the headset.
For example, I have two "similar" headsets, one that came with Samsung Galaxy S and another that came with Samsung Galaxy Tab 10.1. Even though they look similar to the naked eye, if I use the Galaxy S one with my Tab, I only get mono sound due to a minor difference in the TRRS layout.
Sometimes I can remedy this by pulling the jack a little out of the plug, but it's very tricky to keep it in the correct position.
Anyway, you should test the jack with different headsets to verify that there's no physical damage to the jack.
