My daughter has a Samsun Android tablet that has ran out of space so I purchased an sd card. The card is mounting and I reformatted it from the Android device but the device is still claiming to be full when she tries to install new apps. I tried this site http://www.howtogeek.com/242937/how-to-set-up-a-new-sd-card-in-android-for-extra-storage/ but that app never popped up when I inserted the sd card into the Samsung's slot. Any ideas on how I can give her extra app storate space for her tablet? Thanks.
