"Left handed death-grip"? Ah those damn left-handed idiots, always screwing stuff up for everybody else. ;)
I'm right-handed and I pretty much always hold my phone in my left as that leaves my dominant hand for doing anything useful: navigating apps, mousing, one-hand typing, fumbling through pockets, opening doors, etc. Why tie up my dominant hand just to hold something?
I am left handed btw.
