Howdy, thank you for asking us your question about the Samsung Galaxy Tab A11+. Smart Switch is a convenient app that lets you quickly transfer files from your old phone to a new Galaxy phone or tablet. However, not all content can be backed up and transferred with Smart Switch. Here are the files that are excluded from a backup: * Contacts: Contacts saved on the SIM card, social networks (Facebook, Twitter, etc.), Google accounts, and work email accounts are excluded. * Calendar: Appointments synced with external accounts, such as Google, and calendar stickers are excluded. * App data: Data saved in private storage cannot be backed up. * Email: Social Hub and Premium accounts (Push email) are excluded. * Live wallpapers and themes: Live wallpapers and themes are excluded. You can reinstall these from the Galaxy Store. Feel free to check out, "Content that can be transferred with Smart Switch" if you would like to learn more about Smart Switch. Then, reach out to Support afterward if you'd like further assistance. Thank you for being a steadfast Samsung customer. - Debra
