I try to use 64GB and 128GB SD card on my Vivo V3 but device still shown “SD card busy” .. That i have mount SD card or got do something with my phone??
According to specs, it should handle up to 256gb using SIM 2 slot. Make sure the SD card is preformatted to FAT32 or ExFat. You can do this using a computer or the Settings –> Storage option on the phone.
The smartphone is reading or writing on the memory card. And it is taking time, hence it shows SD card is busy.
