The most common issue folks run into is not inserting the SD card fully BEFORE connecting a card reader to their phone. The phone does not typically read the SD card if it is pulled/replaced while the card reader is already connected to the phone or tablet.
- Always push the SD card in fully BEFORE connecting to your phone. The SD card should push and "click" into place. It is ejected by pushing it again to "click" out. If it is not fully clicked into place before connecting to your phone it won't get picked up.
- If you already connected the reader to your phone and then clicked the SD Card into place, this won't work either. The SD card needs to be fully clicked into place, and THEN connect the reader to your phone.
If the above steps are properly followed, just be sure the app "ES File Explorer" is already open on your screen, then connect the reader with the SD card already "clicked" into place fully, and "USB" should appear in the ES File Explorer app. Now dive into "USB Storage" and find your files here.
