Case to better hold Tab S 10.5 in Portrait form? topic

I really like the Tab S 10.5, but my main only real gripe (aside from the speakers and bloatware) is that its not easy to hold it in portrait mode. One of the long sides has the volume buttons, which somewhat get in my way when I grip that side, and the other side has the capacitive buttons in the middle

Does anyone use a case that makes it easy to hold it in portrait mode?

Thanks!
