I've searched and seen many posts on slow sd's, and separately many posts on sd corrupting pics and vids, and I seem to be observing both.
The sd card is a 95mbps Samsung (uhs-1 class 10 u3) , phone is an lg g6. Phone is fine (non rooted), and all apps were working fine. Then when I started pointing apps to the SD, I noticed transfers were extremely slow (I'm only getting between 4-10mbps up and down), and in some cases things were breaking like vids, pics, and off Spotify not loading, line map downloads failing.
Please help. Thanks!
I didn't find the right solution from the Internet.
