In all fairness, my right thumb is 0,5" shorter due to surgery a long time ago. The scar takes away some feeling, add to that I always preferred my left ear for making calls. The hearing is probably slightly better on that side, which in turn could be caused by my lazy left eye I was born with.
And I'm not kidding about that.
But since I use my dominant hand for writing, I also use it for typing on my phones.
And I suspect Samsung made a mistake with that in placing the fp scanner suited for people holding it in their right hand. Which will most likely be left-handed people, which in turn is about 20 percent of the world population. Or was it 10?
I see some using it one handed, and most others one hand holding and other hand typing/ two handed holding and typing.
