Samsung Galaxy S8+ "SM-G955FD"
Android 9 One UI v1.0 (updated to the latest patch)

what I did :
1-Used SP path changer "SPPC3.0.1" and changed "Titanic_NEU_StreetPilot_v2.37_signed.apk" path to "storage/emulated/0/Garmin"

2-Moved the new resulted file to phone internal stoarge.

3-Extracted "Garmin" folder from "TitanicOriginal-Garmin_NEU" and manualy moved it to internal stoarge in "Android\data\com.garmin.android.apps.gmobilext\files"

4-Install streetpilot using the new file

5-Activated phone GPS

Finding:

a-after installation is completed I used "Open" to start sp and it did run very nice
b-Closing and starting SP no issue so far (SP telling me there is no maps to be loaded)
c-Restart it Phone.
d-Closing and starting SP no issue so far (SP telling me there is no maps to be loaded)

e-Moved my needed files "gmapprom.img","gmapbmap.img",gmap3d.img" and JCV folder to garmin folder.
f-SP crash immediately and hide in the background but by pressing on its icon from the top dropdown twice or more it will run just fine
g-Closing and Restarting it behave as in step "f"

Iam not sure but the map loading process is failing and forcing it to crash and run in the background.

I have tested many releases by "Titanic" and this one is by far the best so I think we are getting close to simple smooth happy StreetPilot
