Need more storage on your android phone? 

Some phone models allow you to increase storage with a microSD card. Not only does this let you store more media and apps on your phone, but it also offers a way to transfer large amounts of file data between your phone and other devices. Another advantage is that you can plug some Android phones into an external USB storage drive and browse its files. If your phone has a USB-C port, you can simply plug in a USB flash memory drive with a Type-C connection.
