My concern is with my Tab A6 Samsung 2016 which I purchased sometime ago. I unfortunately discovered I can't use my sd card as the default memory. My frustration now is I can barely use it for the purpose I bought it--I guess I expected so much from this crappy tablet. My question to samsung and to anyone that cares to read is why in the world should samsung make such a useless tablet without sufficient storage memory? Is there any possibility of setting the sd card as the default storage memory? And for goodness sakes what we're the developers thinking of???
