gobbe is there some way to.make them think its an old iphone or smt ??
Since apps built to run on Android can't run on iOS, it would be quite infeasible to trick an Android app into thinking it's running on iOS.
More generally, apps have access to lots of information that makes it feasible to guess which device model is being run on, and there are many features an app could use to guess which Android variant with high probability. Any app using the Android attestation system would have a good chance of detecting spoofing.
