How to change the font of mobile phone is unsuccessful.

If the phone can't modify the font style, we suggest that you:

1. Check whether the font style is supported: Settings-Display-Font Style-Change Attempt.

2. If you can't click the options under the font style, please back up the data (contacts, text messages, photos, etc. ) and try to restore the factory settings (Settings-Reset/Privacy-Restore Factory Settings).

3. If the downloaded third-party font software cannot be changed, it may be a software compatibility problem. You can download other software and try it.

If the problem still exists, it is recommended that you take the machine, purchase invoice and warranty card to the local Samsung after-sales service center for testing.
