Hi Samsung, is there something that can be done to sign in to existing games when upgrading or getting a new phone. I don't like that I need to restart my favorite games and can't continue the level.
Sometimes Smart Switch will transfer App data, it depends on how it was connected on the old device. Typically to retain app data like game saves, etc. you would need to connect the app itself to an account. For example on my Note9, I use the Game called Emoji Blitz from Disney. I connect the app to both my Google Account and Facebook account so that now when I sign into the app on a different device, I use the Facebook or Google info and it automatically transfers in the save data.
