When i boot my phone I have access to write on sd card. Take pic save it, pc transfers, voive rec and more all no prob to sd if its just after boot up. Dont use phone for a while and access is blocked, transferred files get lost into LOST.DIR on sd card. If I use fike manager I set the root of my sd card for permission but still no access to write to or delete data.

Phone is rooted sm-G360H android 5.0.2

Any help to solve appreciated
