I can't copy/delete/move any files from my phone, not even with my laptop

[AC Question]

I tried to backup some photos with an app called wondershare dr.fone, and thing has gone bad, I think the app tried to root but failed, and I unplugged my mobile (s5) from the laptop, hours later I noticed that the gallery doesn't save new messages from what'sapp, doesn't save photos from the camera app, and I can't copy, move or delete any file from the gallery, not even from one album to another, and I can't even upload them or copy them to my laptop. HELP.
