Eu tenho o Moto G - Android 4.4.4. Eu emparelhei meu telefone e queria transferir os arquivos do telefone para o laptop (Ubuntu 14.04). Mas não é capaz de fazer isso.
Embora eu consiga navegar pelos arquivos via Bluetooth e poder acessar fotos e reproduzir vídeos no Laptop (que estão no meu telefone)

Parece que a política de firewall / segurança impedindo a permissão RW, primeiro verifique as regras de firewall do Ubuntu, habilite ou permita seu acesso não ao dispositivo, confie tanto no dispositivo quanto na conexão segura. Verifique também as configurações do telefone celular.
Lembre-se: as regras de firewall padrão sempre não são uma boa ideia. Se assumirmos que o hardware está funcionando, verifique a segurança e o conjunto de políticas em ambos os dispositivos.
