Operating System
Buying more storage for Samsung phones is possible through microSD cards (up to 1TB) on compatible models like the Galaxy S23 series, or by upgrading to a device with built-in storage if your phone lacks expansion. Always verify compatibility via Samsung’s specs or your device manual first.
Many Samsung models—especially mid-range and older series—include a microSD slot, letting you add storage without upgrading. 🔥 For example, the Galaxy A series often supports this feature, while newer flagships like the S23 Ultra don’t. I’ve found that using a high-speed UHS-II card (like Samsung’s EVO Select) makes a huge difference for 4K video storage, but apps installed on the SD card may run slower than those on internal storage.
If your phone lacks a slot, consider cloud storage (Google Drive, Samsung Cloud) as a temporary fix, though it’s slower and less reliable for large files. Always back up critical data before swapping cards—corruption can happen if you remove the card while apps are accessing it.

Which Samsung phones support MicroSD expansion?
Samsung's approach to storage expansion varies dramatically between its device lines. The key factor lies in whether a model includes a physical microSD slot—something you'll find primarily in mid-range and older flagship devices.
For example, the Galaxy S22+ and Galaxy A54 5G both support microSD cards up to 1TB, while newer models like the Galaxy S23 Ultra and Galaxy Z Fold 5 have eliminated this feature entirely. This shift reflects Samsung's focus on built-in storage solutions rather than expandable options.
The performance difference between storage types matters significantly for media-heavy users. Samsung phones with microSD slots support UHS-I and UHS-II speed class cards, with UHS-II offering transfer speeds up to 312MB/s—ideal for 4K video storage.
However, apps installed on the SD card may run slower than those on internal storage due to Android's limitations on SD card performance.
I've tested this with a Samsung EVO Select 256GB UHS-II card in a Galaxy S22+ and noticed noticeable lag when moving apps to the SD card compared to keeping them on internal storage.
Here's what you need to know about compatibility:
- Expandable models: Galaxy S22+, S22 FE, A54 5G, A73 5G, and most Galaxy M series devices
- Non-expandable models: Galaxy S23 series, Z Fold 5, Z Flip 5, and Note 20 Ultra
- Storage limits: Maximum 1TB microSD capacity, but actual usable space may be slightly less due to formatting overhead
The science behind this involves Android's storage architecture. When you insert a microSD card, your phone treats it as separate storage rather than an extension of internal memory. This means you can't install system apps on the SD card, and some apps may refuse to move there entirely.
The exFAT file system is recommended for cards larger than 32GB because it handles large files better than FAT32, which has a 4GB file size limit—a critical consideration for 4K video files or large game installations.
What most people don't realize is how this affects app performance. While you can move some apps to the SD card, Android's design prioritizes internal storage for app operations. This means apps on the SD card may launch slower and could even fail to update properly.
I've seen this firsthand with gaming apps on a Galaxy A54—some titles would crash when trying to install updates while the SD card was in use.
For media-heavy users, the choice becomes clear: if you need portable storage for large files, a microSD card is your best bet—but only if your device supports it.
The Galaxy S22+, for instance, handles a 512GB microSD card beautifully for photography storage, while the S23 Ultra users are stuck with whatever built-in storage they purchased. 💫
