Assuming this is for Android, the APK would no longer be signed and would cause all login attempts to fail.

Have a read about "SafetyNet Attestion API" for Android.

You could patch Android and run it in an emulator. Or patch Snap not to care. Not super familiar, but there should be a way. Client side security can only do so much.

You can't patch Snap to not care because the safetynet process is (roughly) like that: The App asks the Play libraries whether the phone is okay. This is verified (in part) on the Google servers, so the Snap servers can ask Google whether a call came from a non-tampered phone. The client can't do anything about it, except tricking google into believing the phone is not tampered with. Which is notoriously hard, because nobody knows how the process really works.
