我已经开始注意到我正在测试的一个设备上出现问题，按住电源按钮不会显示允许我关闭设备的对话框。
当我按住电源按钮时，这会被反复发送到日志输出中，这似乎是尽可能快的速度：
10-27 11:07:31.853: INFO/InputDispatcher(149): Delivering key to current input target: keycode: 26, scancode: 116, action: 0, channel '408013a8 com.android.launcher/com.android.launcher2.Launcher (server)'

一旦我释放电源按钮，这些日志垃圾就会停止，屏幕会关闭，但设备处于睡眠模式（好像我根本没有按下电源，只是按下并释放）
这不是100％一致，但我没有注意到任何导致它的模式或原因/结果。
还有其他人遇到过类似的东西吗？
