I´ve got a Galaxy S21 Ultra that I can´t do anything with when I attach it to a computer, I never ever get the question if I want to transfer any files it just charges.
I even tried in the Developer mode to choose file transfer as the preferd mode but still it just charge 😞
I´ve tried a number of cables but it doesn´t matter.
Anyone have any good ideas because I am running out of them. Perhaps I should turn back to my Huawei P30 Pro again because then it works like a charm.
