Google announced on September 17 that it will auto reset app permissions for unused apps starting from Android 6 and above devices.

Auto-resetting app permissions were introduced in Android 11 as part of a continually expanding Android feature set aiming to automatically limit apps you don't use. When you don't use an app for a set period of time, Android will automatically strip the app of any permissions it has been granted, limiting it from tracking you in the background or accessing data. It's a nice feature for less tech-savvy people who aren't interested in manually organizing the inner workings of their phones. If you open the app again, it can ask for all of those permissions again.

Releasing the feature to Android 6 and up means that it will reach billions of users. Even Google's 18-month-old chart shows Android 6 at 84.9 percent of devices. Users will get the feature starting this December via a Google Play Services update, with the rollout finishing sometime in Q1 2022. Once you have the update, "the system will start to automatically reset the permissions of unused apps a few weeks after the feature launches on a device," Google says.
