I depends on device.uuid to control my users, Does UUID change when factory reset, in Phonegap android.
Update with new information:
On Android 8.0 (API level 26) and higher versions of the platform, a 64-bit number (expressed as a hexadecimal string), unique to each combination of app-signing key, user, and device. Values of ANDROID_ID are scoped by signing key and user. The value may change if a factory reset is performed on the device or if an APK signing key changes. For more information about how the platform handles ANDROID_ID in Android 8.0 (API level 26) and higher, see Android 8.0 Behavior Changes.
Note: For apps that were installed prior to updating the device to a version of Android 8.0 (API level 26) or higher, the value of ANDROID_ID changes if the app is uninstalled and then reinstalled after the OTA. To preserve values across uninstalls after an OTA to Android 8.0 or higher, developers can use Key/Value Backup.
Old answer
device.uuid on android it gets the native android.provider.Settings.Secure.ANDROID_ID
According to the docs
A 64-bit number (as a hex string) that is randomly generated when the user first sets up the device and should remain constant for the lifetime of the user's device. The value may change if a factory reset is performed on the device.
Note: When a device has multiple users (available on certain devices running Android 4.2 or higher), each user appears as a completely separate device, so the ANDROID_ID value is unique to each user.
So yes, if the user do a factory reset the value may change.
