我最近将Samsung S3（T-Mobile）更新为Android 4.1的OTA更新。自更新以来，手机屏幕向下电（手动或计时器）后，重新打开屏幕关闭运行应用程序。我不知道这是否是带有Android 4.1的一些新的默认行为，或者如果这是T-Mobile自定义（"功能" ）或错误（带有Android或T-Mobile的自定义）。
我没有发现有关此行为的信息，也没有任何设置解决该行为。你的手机做了什么？当我重新启动屏幕时，我更愿意使用该应用程序运行。当我丢失推出当前应用程序的其他应用程序时，我特别讨厌它。
注意：升级后我没有擦除数据，设备上没有安装任务杀手。
谢谢，
I recently updated my Samsung S3 (T-Mobile) with the OTA update to Android 4.1. Ever since the update, after the phone screen powers down (manually or on timer), turning the screen back on closes the running app. I don't know if this is some new default behavior with Android 4.1, or if this is a T-Mobile customization ("feature"), or a bug (with Android or T-Mobile's customization).
I can find no information on this behavior, nor any setting addressing it. What do your phones do? I prefer having the app running when I power the screen back on. I especially hate it when I lose the backstack of other apps that launched the current application.
Note: I did not wipe data after upgrade, and no task killers are installed on the device.
Thanks ahead,
