I have this internal android app for the phones. The company has it's own custom management for all the devices. Hole thing is working based on the imei , as a unique key to identify each phone.
As you know from Android 10, the imei identifier is not accessible anymore. I have read a bunch of post and articles, but none seems to satisfy my needs, as I need an unique identifier, that lasts also after factory reset, reboot, uninstall and so on.
Please any suggestions, are welcomed.
