[AC Question]

My Galaxy Tab 3 automatically updated itself to Android 4.4.2 today, and I immediately lost several major elements of functionality I need from the device. Is there a way to go back?

(That's the whole question. I desperately want the previous, WORKING versions of what I had. Here are the details. Why would they DO this?? Or am I doing something wrong?)

Three functional downgrades seen so far:

(1) I use the Gallery to show 1000s of photos, stored on a microSD card always left in the tablet. The previous version stored the thumbnails somewhere, so that when Gallery opened a folder it showed all the thumbnails instantly, making browsing easy. The new version doesn't; when I open a folder, it takes almost 0.3 seconds to construct each thumbnail on the screen, unacceptable for multiple folders with ~3000 photos each, and the NEXT time I open the same folder, the same thing happens, so it's not even storing the thumbnails for future use.

(2) Google Maps, which previously would store one complete offline map for a limited area, has had this feature seriously downgraded. With the new version that downloaded itself right after Kit Kat, you can save multiple named maps, BUT when you open a saved map offline and zoom in, there are almost no street names (except a few big ones), only street outlines.

(3) My Files: When I go up or down a folder level into the SD card, it used to be almost instantaneous. Now it takes 30-40 seconds each time, which is ridiculous. Even when I want to close My Files I have to go to "Active Applications" and force it closed instead of using the back button.

Yes there is
Using some software called ODIN and the correct Firmware from Sammobile
But you will have to do a Factory Wipe after as your rolling back
