Google Play Store Version: NFS Most Wanted
Yes so I was browsing in the google Play Store and wanted to find out if any new updates to this spreading 5003 error problem. Looks like EA has listened and decided to host the 600mb file on Google Play's server for direct download. The in game store is working but no way to connect to an Origin account. It's a FireMonkey's Studio game.
They have also fixed NFS Most Wanted. I found it apparent that the game loading times have been reduced and the phone doesn't run half as hot as it used to running the game.
If you have purchased NFS Most Wanted on the Google Play Store go check and see if yours says Last Updated on December 6, 2017
In summary you should not need to download the game files directly from EA servers. The apk and obb files are hosted on Google Play Store.
Just back up the apk and obb and do not lose it!
