You can disable programs or apps that you don't use.
Or can not be uninstalled. To free up memory.
Google has a lot of apps on this that I have disabled.
And apps that you download (most) of them can be moved
to the internal "nand flash" "SD Card", storage drive (16gb),
well actually about 12gb. Since the Android OS and
it's support files takes some room in the 16gb area.
Most all of it, you just need to switch the app location from tablet to the SD card. You cannot do this with the pre-installed apps but you can with the those you install.
Now that I have this tablet, I am answering my own question, in case anyone else is wondering. Out of the 16GB of total storage, only 1 GB is allotted for apps, which includes space that the pre-installed apps take up. Some apps can be moved to the "internal SD" card, which is not the same as an SD card that you would insert, but only a few apps can be moved.
it came with a bunch of apps already loaded I removed majority of them. currently have 54 apps loaded which = 753 MB. and have 132MB left of internal storage. NAND Flash I have 12.91 GB of storage left. I can also get a mini SD card or a USB and add storage.
you will have to go into settings and move apps to sd card, that is where the rest of your storage space is.
It is set up really oddly. It has 1GB on board memory and then has an internal 16gig card that is labeled within the system as an "SD Card" so you have to move apps over to it in order to keep it running smoothly. I also disabled several of the installed apps and uninstalled their updates. All-in-all it's a great little tablet for the price and so far my daughter loves it!
close to 1 GB, the most apps we were able to download was 15. And you can not delete or uninstall the ones that come on it, so you are stuck with them.
