Quase todas as perguntas sobre problema com o cartão SD têm resposta "Formatar o cartão SD pelo seu telefone". Então, qual é a diferença quando formato cartão SD por PC ou por telefone? (sistema de arquivos é FAT32)
Almost every question about problem with sd card have answer "format sd card by your phone". So what is the difference when I format sd card by PC or by phone? (file system is fat32)
I suppose the biggest reason why people make such recommendation is because an end user could easily end up formatting the card with an incompatible filesystem, like NTFS.
This in turn will cause further confusion to the user and additional forum posts.
It is safer to just ask them to format the card using the phone's interface.
