Hi! 
What can app developers actually see and how are they identifying me?
The MAC-adress, the IMEI, the device ID?
How can I prevent them from identifying me? The only way that I know, is changing the MAC, IMEI, and device ID.
For example: I download an app called XY. It knows my phone.
Now I uninstall XY, and install it again, but I dont want that it already knows my phone(A). I mean I want that the app XY thinks that I'm a other mobile phone(B). It dont matters that the app knows that I'm using a 1+1. It matters that the app knows that I'm using another 1+1. And how can I get back, so that the app XY thinks that I'm again using my phone(A)?
Or the question expressed differently, how can I have 2 ''different'' phones in one mobile? For example I could buy another 1+1. But I want to have to two different identities in one phone. Is that possible?
How can I do that? Its nothing illegal that I'm trying to do
Thank you very much, and best regards from germany!
Happy new year!
