That's brilliant! Thank you. I have just received my new A21s today and could not work out how to move anything to the SD card. I had downloaded just one photo, from my Google Photos in the cloud and have now moved it to the SD card, so thanks again.
Major disappointment on this OS limitation. Guess I should have done a better job researching before buying the A21s...I guess I'll try to get on with without the feature and 32gb, but will probably return the phone to Amazon before the return window closes.
You can move apps, files, images, and videos from your internal storage to an SD card using the Samsung Smart Switch app. You can also use this app to transfer files to different devices.
remember, not all apps can be moved to SD cards, example of these are Google, Facebook, etc... this is because the app itself does not let it to
to move an app:
Settings → Apps → tap the desired app → Storage → Move/Save to SD card
for managing files, we can use Files by Google app so we can swing any files back and forth to SD card/internal storage
