Re: Samsung tablet storage

The issue you are experiencing turns out to be very common amongst Samsung tablet users. There are a few issues.
One issue is that you can't assign the external storage MicroSD card to be "internal storage", at least not out of the box. If you could, then apps that you download would be stored on that SD card and run from there.
I believe you can manually move them across from internal storage to external storage but some apps will likely be designed to run from internal.
You can circumvent that whole issue by putting a different operating system on the device. Marshmallow seems to be the one recommended.
A larger issue is that Samsung Galaxy tablets have a "cache" issue. This is likely where your missing storage capacity has gone. Apps leave "stuff" in the cache and you have to therefore routinely clear it out. If you don't you'll eventually run into trouble.
I found the instructions below which show how to clear out the entire Cache partitiion. I can't vouch for the safety or effectiveness. Here they are:
To wipe the cache partition, follow these steps:
1 Press and hold the Power/Lock key, tap Power off, and then tap OK to turn off the tablet.
2 Press and hold the Power/Lock key and Up Volume key at the same time.
3 Release the Power/lock key when the Samsung logo appears.
4 Release the Up Volume keys when the Android image appears.
5 When the menu appears, press the Down Volume key to select Wipe cache partition.
6 Press the Power/Lock key.
Doing the above will not touch your installed apps or personal data
Once the message, “Cache wipe complete” appears on the screen below the menu, Press the Power/Lock key to select Reboot system now.
I read also that you can download an app that provides a simple 1 click solution to clearing the cache. There was a user out there however who had gotten into a catch 22 situation. His device (and cache) was so full that he couldn't download any further apps. So he couldn't download that actual app he needed to be able to clear the cache!
So in summary the solutions appear to be:
1. Manually move apps over to your SD card
2. Clear the cache partition
(or clear individual apps cache)
3. Install Marshmallow on the device so you can set the SD card to be effectively the internal storage
