If I install an app, uninstall it, finally install it again at a later time, how the app can detect if it was installed on this device earlier? What are the device unique id's that it can detect?
- Android device ID: I changed it with device ID changer (now removed from play store, can't give link).
- google advertising ID: changed that too
- didn't login into the app with any accounts earlier used.
What other ways the app an app can use to detect if it was installed earlier on the device. I do give internet access to the app.
No IMEI, I'm using a tablet.
