Traditionally, Android permissions were granted during application installation and lifetime. With Mashmallow came work-time permits, and Android 11 assumes that the permissions do not extend slightly. What else, is it possible? stop it so the permissions expire.
Third-party developer preview of Android 11 includes the option to automatically deny app permissions if it's been a while since you've used it
Permission with expiry date
The developer preview of Android 11 lets us see where Android's future lies in security and approval. Increase user control about app permissions, to the extent that they can be modified so that the permissions are automatically generated.
A particular option is called Automatically clear permissions and doesn't work automatically, at least in the developer preview. To edit them you must go to the application information, in that section Permissions
As shown in the window, this option will disable the app permissions in the background you haven't used it in a few months. Google does not specify exactly how much the request was granted to Grace or when a warning will be displayed that app permissions have been disabled for this reason.
The purpose is clear. Protect the programs you have installed once and forget about it Use resources from your mobile phone or they may get information about your cell phone usage, when you don't use it often. It's its way, a mode similar to the specific battery installations of certain products, which prevents some applications from starting automatically by their use.
