As a workaround, I have been forced to shut down phone and physically remove SD card from slot, reinsert card, then restart phone. You can check this link on how it works. [HOST]: SanDisk Ultra 64GB Micro SD tarjeta para teléfono Motorola funciona con Moto G Fast, Moto G Stylus, Moto G8 Power Lite (SDSQUARG-GN6MN). Impressão digital, Sim, na volta. Ampliável? (Slot SD), Sim, Slot para SD ou para segundo cartão SIM. Any SD Card classified as UHS-I should work fine. I tried using Eject function. Outros telefones com GB de armazenamento. Segurança. .
