Instead, the S21 series relies on internal storage. However, with the Galaxy S21 series, the company changed its stance and no longer supports microSD cards. SD cards used to be one of the biggest selling points of smartphones from Samsung. The Galaxy s20 can take a micro SD memory card with a capacity up to 1TB. Some types of SD memory cards have a ‘A1’ rating, which means they can store more data than other types of cards. The Samsung Note 20 does not have an SD card slot.
