I just switched from a pixel 2. I had a Google Account and backed up all my Contacts. I didn't copy anything over to the Note 9. When I set up my Google Acct on the Note it then synched all Contacts, and Contact Groups. I knew it would synch the Contacts but what I didn't know was the Play Store under Installed had a record of all my installed Apps and under Play Store Library was listed every App I had ever used but not currently installed. All I had to do was click on the Apps to either Open or Install. A piece of cake.
