What's the best smartphone with SD card support?

Episode 1281 (1:13:35)

Steven from San Diego, CA
Samsung Galaxy Note 4

Steven has an old Nokia phone that he's been using for awhile, but now Sprint is going to stop supporting it. He was looking at phones that have SD cards, but can he connect to an external drive via USB? Leo says not really. There are phones that can use SD cards up to 200GB, though.

He could go with a small Samsung Galaxy Tab. It would be like a giant smartphone with a 3G connection. The Galaxy Note IV is ideal because it has a removable SD card and battery, so he can then swap out the battery when he's running low on power. Or, he could get the Samsung Galaxy S7. It's not cheap at $800, but it will get the job done.
