The Galaxy S21 series of smartphones marks the end of Samsung's support for microSD cards. The new Galaxy S21s bring a lot of features, such as updated cameras, a more consistent 120Hz display, support for the S Pen on the Ultra, and so on. But the possibility of using a micro SD to expand storage is gone.
All three phones in the series – Galaxy S21, S21 + and S21 Ultra – they don’t have microSD expansion. The phones start with 128GB of internal storage and can go up to 512GB on the S21 Ultra or 256GB on the S21 and S21+.

The Galaxy S21 series, including the S21 Ultra, does not come with a micro SD card slot
Once you’ve used up that capacity, you’re at the mercy of cloud storage, just like iPhones. The change isn’t entirely surprising, since the Galaxy Z Fold2 and Z Flip also lacked micro SD card slots. But it’s still going to be a big one for many.
Removing the micro SD slot is a loss for the consumer
The removal of microSD card support probably won't be a deal-breaker for many potential buyers. However, it's yet another hardware feature that mid-range and entry-level phones will (likely) continue to offer for years to come, giving them a big advantage over more powerful devices. And that's on top of the Galaxy S line's high price tag.
The option to use microSD cards is still a great way to store large amounts of photos, movies, and music. It’s a great mobile solution because you can take your content with you wherever you go. Samsung is the largest manufacturer of Android devices and often serves as a model for other companies. It’s no surprise to see more brands follow suit. No recent phones from OnePlus or Google support SD cards, but most devices from LG, Sony, Motorola (except Edge+), and others still have SD slots.
As if removing the charger and earphones from these top-of-the-line devices weren't enough, now there's no storage expansion either. Who will be the next victim of minimalism?
