So many apps upon installation request you permission to access sensitive information to track you, such as:
Wifi connection info
Identity (Device ID, device model and other stuff)
Call history
Files

So using a VPN is not sufficient, they can track you by just checking the identity and/or your call history (it is unlikely that 2 different people made a call to the same numbers at the same day/time).
About files, probably they have access to the whole file system, right?

How can i hide or fake that info ?

For the Wifi connection, maybe a VPN is enough but i am not sure.


What about the last two?

I don't think that info can easily be faked to avoid being tracked, but a lot of people simply don't understand the app permissions. If you're in a security sensitive position or something that requires excess protections, then feel free to ignore this. It's just that all these permissions aren't setting you up for being tracked by the developer.

For example, your Wi-Fi connection info in the list. Some apps allow you to set to only use Wi-Fi and not mobile data. So those would need to know when you're on Wi-Fi to work. This article goes into more depth about permissions and how to be smart about scrutinizing them.
