Not bad at all.

Make sure to find a proper font. Sometimes there might be issues while changing it. Check different fonts on https://upfonts.com/liberator-font/, but test them before adding them, so you won't have to redo everything.
It depends where you are going to change them. If it's a blog, you might end some issues. If it's a project, it should be easy.
Hopefully, I could help even a little bit, as far as I can see you received already all the necessary answers on this topic )))))))

The same

Eu estava procurando as mesmas opções para alterar minhas fontes no celular, mas não é tão fácil mudar para que eu possa escrever no bloco de notas e enviá-lo para o texto do telefone mais tarde, mas ser um escritor em https://olatcc.com.br/comprar_tcc, então eu gosto de fazer muitas coisas, especialmente para escrever conteúdo, contos e fantasia para ser mais criativo

At work we use old style Samsungs, GT-S5611V.

You can change the font size when reading texts - using the volume keys.

But can anyone tell me how to change the font size when writing texts please?

Much appreciated.
