私は2つのAndroid携帯電話を持っています：Nexus SとT-Mobile G2。私はちょうど内蔵のマイクを持っている新しいヘッドフォンを購入しました。 Nexus Sは音声入力を認識しているようですが、T-Mobile G2はそうではありません。それはハードウェアの制限ですか、または私のG2とIcecream SandwichでAndroidを実行しているのか、私のNexus S？
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.
