Wait you got a new card and it's having the same issue...?
How is the card formatted? I've never had this issue, and I use TWRP to backup and restore daily. I'm constantly blowing up my phone for testing, so I depend on it to backup and restore consistently...
I assume this issue is not present if you use the "internal" SD?
Yeah, new class 10 adata 16gb card formatted to fat 32. Internal works just fine, limiting on space tho.
I tried a clean wipe w rsd, needless to say that didn't work out. I don't know what else to try fixing it tho. You have any ideas?
