The mobile phone screen is broken. How to delete the message inside?

If the phone can't operate normally (such as screen damage, power failure, etc.). ), you need to back up the data in your mobile phone. I suggest you refer to the following:

1. If the mobile phone can be turned on normally, you can download Samsung Kies software /S change assistant from your computer to back up files such as address book (different models of mobile phones use different PC suites), or you can use other third-party mobile assistant software to make backup attempts.

2. If the mobile phone can't be turned on, please bring the purchase invoice and maintenance card, send the machine to the nearest Samsung service center, and the engineer will judge whether the data can be backed up after testing the machine on site.
