Non-techie here. I have a Samsung Galaxy J7 Pro and installed the Anybooks app which is now discontinued. Since I had downloaded 1 GB of books, I need to migrate the app and data to a new phone.
The Anybooks app stores user data in the cache. I have tried APK backup apps and Samsung Smart Switch, but only the APK is backed up without the crucial user data.
How can I back up the app and data?
