I'm sorry about the issue. After you have downloaded / installed the Kindle app on your Samsung phone, then open the Kindle app, then sign in with the email address (the email address she's been using to purchase books) associated with her Amazon account and with her Amazon account password, then you will get her books.
; (Note: If you had already signed in with your own Amazon account, then in the Kindle app on your phone, go to menu / settings, then go to the option Account (or registration option), then select the option Deregister, and confirm (or you can uninstall the Kindle app then reinstall it). Then sign in with her Amazon account.)
- You can also read her kindle books on your computer at the Amazon website below:
, at the above website, sign in with the email address associated with her Amazon account and with her Amazon account password.
- Note: If she has forgotten her Amazon account password, she can reset it at the Amazon website below:
