I have used TV anywhere on my Samsung Galaxy Tab 4. The latest update wouldn't install - it says ..."can't be installed on USB storage or SD card. Error code 18. But I am not trying to install on USB or SD. I removed the original installation but still get the same error message when trying to reinstall. Can the Virgin people please look at this issue.
Sorry to hear that TV Anywhere is unable to install on your Samsung Galaxy Tab 4.
This does sound like the app is trying to install on an SD Card rather than the internal memory. Do you know if there is an SD card placed within the Tablet? If so remove this and if there is any data stored on the tablet from trying to install the app, remove this also, then try to re-install the app to see if that will work.
