There is this odd file that reappears in my storage under downloads even after I delete it. It is called s76fg978fds6g3. The icon for it is like a blank piece of paper and when I try to open it it says "unable to find application to perform this action." I have deleted it 3 times and it keeps coming back. Not much of a phone expert and searching up the file name on Google hasn't helped either. Just need some more information.
