Best microSD cards for Galaxy S8 2022
Making space for more content with these microSD cards.
The Galaxy S8 offers 64GB of internal storage, which might be more than enough for some. But suppose your phone is close to capacity with all your music, video, or pictures. In that case, you should take advantage of Galaxy S8's expandable storage and grab a quality Galaxy S8 microSD card. Unfortunately, Samsung doesn't let you use your microSD for adoptable storage, which means you won't be able to use it as you do the phone's internal storage. Still, it's a great place to store your treasured photos and videos or side-load your favorite music, media, and games.

High capacity, low price
SanDisk is a respected brand for memory cards and storage products and cards like this show you why. The SanDisk Ultra 200GB is a Class 10 card with quick transfer speeds (up to 100MB/s).

Give your Galaxy S8 some extra breathing room with a microSD
Chances are you've owned your Samsung Galaxy S8 for a while now, and you're nearing storage capacity. So whether you're constantly deleting photos or apps to clear up space on your phone or want to load up the phone with your favorite media, there's really no better time to buy a microSD card for your Galaxy S8.
However, it's important to note that the popularity and small size of microSD make them a prime target for counterfeiters. So read the fine print. Our best advice is to try and stick with trusted brands from trusted sellers, always check the cards when they first arrive, and immediately file a claim to return or exchange the card if you suspect you might have purchased a fake.
The absolute best microSD card for Android you should get is the Samsung EVO Select 128GB, which is available for a great price that routinely drops even lower on sale. Samsung is a natural choice for a Samsung phone, but SanDisk also offers a pretty compelling option for both 200GB and 256GB cards.
