I'm having the same issue, Samsung Galaxy Tab A. I found a setting to move "stuff" to the sd card, not sure what stuff that will be but will hopefully free up some space on the device. Go to settings, then applications, then under application settings choose internet then advanced then finally default storage and will have a drop down with 2 choices: my device and sd card. Of course choose sd card. Not sure how much info will go to sd I assume anything I search on the internet, cookies, etc. I am going to go into my local Best Buy, there's a Samsung kiosk there! I had someone there set the same setting on my Note 4 and have no idea what he did. Good luck everyone! I hope this works
