Earlier there was Z font app from play store which had a great collection of appealing fonts for One ui but the Samsung fonts got removed due to copyright issues.

1. YOU MUST HAVE ANY VPN IN YOUR PHONE PRE INSTALLED, IF NOT DOWNLOAD SEED 4 ME or ANY OTHER VPN.
2. REMOVE YOUR ALL SIM CARDS FROM PHONE. (MOST IMPORTANT)
