I purchased new Samsung Galaxy S4 phones for my wife and me. We wanted to be able to take pictures and family event videos without constantly worrying about not having space on the phones. The cameras on the Galaxy S4 are wonderful, but that means bigger files too. These &#34;SanDisk Ultra 64 GB MicroSDXC Class 10 UHS-1 Memory Card&#34; are fast and we have not even begun to fill them up.
