In One UI 6, Samsung's default font (One UI Sans?) only applies to Samsung's stock apps. In all other apps, such as WhatsApp and YouTube, the font defaults to Roboto. However, if you apply a font downloaded from Samsung's server or installed through Mono or ZFont, the font applies system-wide.
Does that issue with the default font still exist in One UI 7? Can beta users update me?
We also request you kindly share the beta log file. Also, share video clips and images for better understanding. This will help us to investigate further and resolve this issue.
