Samsung Galaxy Tab 3 says "Storage Space Running Out"...Help! My Samsung Galaxy Tab 3, says: Storage Space Running Out; Some Functions May Not Work.
I purchased a 32 GB SDHC card to see if it would help.  I just opened up the SD card and inserted it. It did not Help. Was that wrong? Can somebody please tell me what i'm doing wrong?
Your tablet is probably saving all your apps and files to your internal storage. You can start saving apps to your SD card or move all your large files onto your SD card manually.

Setting your apps to download to your SD card


Open the My Files app
Navigate to your SD card, and create a folder called Apps
Tap on the icon with four horizontal lines on the top right
Tap Settings
Under Select Directories, tap Set Home Directory
Select the Apps folder you just created on your SD card


Your tablet will now save apps to your SD card in the future.

You can also create more folders on your SD card and move all the bulky files (music, videos etc) that are on your internal storage to your SD card. You will have to do this manually.
