If you don’t want an account linked with your Galaxy phone or tablet any longer, you can remove it. Just be aware that if you remove an account, you will not have access to any of the data in the account unless you re-add it.
This isn’t necessary. To use Android, you must first establish a Google Account on your phone. Setting up a Samsung account is more complicated and includes additional facilities. They both have similar functions, such as backing up data like Contacts, Calendars, Apps, and so on.
Samsung accounts offer a variety of perks, including keeping Samsung apps synchronized across your Samsung devices, access to Samsung Pay, news and discounts, and the Find My Mobile service for tracking your phone.
Users without a Samsung account will just be able to download and update apps from the Google Play Store if they’re comfortable with logging in with a Google account instead.
After you’ve set up a Samsung account, you may use all of Samsung’s features without having to create or log in to any additional accounts. You must establish a Google Account on every Android phone. Your Samsung Account is unlike Google Accounts, and it includes capabilities that aren’t available anywhere else.
