Download a file browser, set it to view hidden files, and copy over downloaded content to the microSD card. Content cannot be played off the microSD card – you need to copy it over to the correct folder on your phone to play it. Merge your microSD card with your phone’s internal storage, tricking your Android into thinking the microSD card is an internal part of the smartphone. Remove and re-insert your microSD card, then tap Set Up once a notification pops up, and tap Use as internal storage. Once you’re prompted, select the option to migrate your data over to your new storage. If you use this method, never remove the card unless you feel like doing an entire phone reset.
