There are a few lacks in Xiaomi Mi A2, and one of them is no Expandable Memory slot on it. It gives high-quality storage through Google Photos, but users can’t store their data through their phones.
Simply put, while 32GB of internal storage should be enough, consumers who require more storage have to pay extra for the 64GB or 128GB version. That’s an additional investment. It could not be very pleasant for Xiaomi’s target audience.
