GYROSCOPE 更新到 2.3.5 后不工作

Question

我的代码以前在 2.2 上可以工作，我可以得到陀螺仪数据，但是在更新到 2.3 之后，它就不再工作了。我还尝试了银河播放器，以确保这不是我手机的硬件问题。它也不适用于那个。有什么建议么？代码如下：

我什至向谷歌报告了一个错误，这是他们的回应：

这些不是 Google 设备，因此您必须与三星联系

Answer 1

我不确定这是否有帮助，但这似乎与您的问题有关：陀螺仪无法闪烁 rom。您可以查看 (Galaxy S2 - Gyro & Compass not working) 并尝试运行建议的测试。

Answer 2

似乎只是三星的问题。向 Google 提出问题并没有帮助；他们把我推荐给三星。
