I think the problem here is the S3 and the Tab E run different versions of Android. The S3 had some options, especially for the controls, that seem to have gone away. A quick search of the Play Store doesn't show an easy solution.
I'm a Samsung guy myself and I feel your pain. The back button seems to disappear a second before I want to use it. I've gotten in the habit of touching the screen every few seconds to keep the buttons lit up.
