Yes it does, and literally any usb stick by a name brand will be fine, so look for the likes of sandisk, Samsung, Kingston, integral. You get any of those brands and you'll be sorted, they each have tons of different models, all shapes and sizes and styles, so which one you choose depends on how you use it, and personal preferences.
Grat choice, purchased my tab7 over a month ago. Still contemplating whether I purchased a s7 or s7+. Generally enjoying the tablet more than my previous i-pad , which I had for year's. Got it a 512gb SD CARD hope it takes formation.
Well after having the Galaxy Tab S3 since its official release, the tablet is still working fine, obviously the battery needs replacing, but I thought that S7 will be the best option since I was planning on buying either a laptop or a better tablet. So I'm really happy with that 🙂
