I upgraded my existing phone from whatever the storage by adding a 64GB micro SD card, I've ordered a new phone which already has 64BG storage, ( Motorola G8) it's probably a daft question, but if I put in the 64GBMicro SD card, will it give me 128GB, which will probably be enough storage for me, ( Apparently the G8 can be expanded to 512GB) or will it cancel out the existing storage and leave me with 64GB? Pardon my ignorance.
