I recently bought a Google ChromeCast with Google TV. I have a 128 GB USB 3.0 which I have formatted as Internal Storage to expand it and install new apps, but when I go to a file explorer (I have tried with x-plorer, file commander, solid explorer) this USB doesn't show, only the internal storage that comes with the CCwGTV. Can anyone tell me what to do?
You need to move the data from the internal storage to the one that you are using now, go to settings -> storage, select the new USB and click on move data.
