Not an expert, but this is what I have done on various devices (even an older LG phone). I made sure neither the game app or Facebook app is installed. I also made sure there's no data of those apps and a good reboot always help. Then install the mod apk. Will need to use signed version at this time. If you still stuck at loading screen, try to clear data/cache of the app to force the game to download the assets as well. If this does not help, I would suggest looking at BlueStacks and play on PC as an alternative. Hope this helps.
