Shutdown - A Root App to Immediately Shutdown Your Phone
Shutdown is a simple root app designed to immediately turn off your phone using the "reboot -p" command. This app offers a straightforward user interface that prompts you to confirm before initiating the shutdown process. However, it is important to note that Shutdown ONLY works with rooted Android phones.
As the app does not unmount your filesystems (just a sync call is made), there is a possibility of data loss. Therefore, the developer, Stefan Simroth, does not provide any warranty and advises users to proceed at their own risk. If you use this app on a non-rooted phone, it will either hang or do nothing. It is also important to note that Shutdown is not compatible with HTC phones.
Overall, Shutdown is a useful app for those who want to quickly shut down their rooted Android phones without having to go through the usual process. However, users must be aware of the risks involved and use the app at their own discretion.
