Forgot pin code, don't even remember setting one up

[Delongeone21]

Hello, I cannot remember the wallert pin, I have tried everything to recover the xml file in /data/data/com.mycelium.wallet/shared_prefs/settings.xml but my phone is not rooted so I cannot access the folder. Does the app have a default? If not would it be possible for me to get a debugable version of the app so I can view the xml file in android studio device explorer? I don't even remember setting a pin up.
