通过在0914的版本复现。
1、在PowerManagerService中isBeingKeptAwakeLocked中添加调试log，发现有wakelock导致屏幕无法进入休眠/屏保
2、通过dumpsys power 发现UndimDetectorWakeLock持有wakelock 未释放
SCREEN_BRIGHT_WAKE_LOCK 'UndimDetectorWakeLock' ON_AFTER_RELEASE ACQ=-7m55s884ms (uid=1000 pid=1015)
3、定位到ScreenUndimDetector类对wakelock进行了处理
09-14 15:46:29.770 1069 1069 D ScreenUndimDetector: User undim, counter=1 (required=2), timeElapsedSinceFirstUndim=1913493 (max=300000)
09-14 15:46:58.835 1069 1069 D ScreenUndimDetector: Screen policy transition: 3 -> 2
09-14 15:47:03.034 1069 1069 D ScreenUndimDetector: Screen policy transition: 2 -> 3
09-14 15:47:03.034 1069 1069 D ScreenUndimDetector: User undim, counter=2 (required=2), timeElapsedSinceFirstUndim=33265 (max=300000)
09-14 15:47:03.034 1069 1069 D ScreenUndimDetector: Resetting the undim detector
09-14 15:47:03.034 1069 1069 D ScreenUndimDetector: Acquiring a wake lock for 600000
调试日志看出ScreenUndimDetector的作用是：进入灭屏时后被手动唤醒，连续两次，这个时候就会触发唤醒保持的功能持续10分钟，这10分钟内将不会灭屏，直到10分钟后。闲置待机的功能才会重新生效。
因此这是AOSP原生的逻辑，对比了android 12和android 13，这个android 13有此代码，android 12 r3并没有此代码。可以判定这应该是Android12 高版本上新加的feature。
QA：这个逻辑是否默认关闭？或者维持现状？

经过讨论目前方案：关闭此功能，默认关闭
#6 Updated by CD- FW-石豪 almost 3 years ago
【根本原因】AOSP 原生逻辑，连续2次主动唤醒屏幕，下一次休眠将在10分钟之后
【修改方案】默认关闭该功能
【验证版本】01.00.X101_20220914_private_userdebug
【修复版本】0915日之后的版本
