A
Android Central Question
It's an answer actually. I removed a free virus scan that would also pop up randomly to ask me to scan for viruses. I couldn't find the ES File Explorer that everyone is speaking of that causes the pop up from the bottom corners of the common apps. Once I uninstalled this free virus scan the pop up from the bottom corner quit showing up. So it's also part of the free virus scan that's on our cell phones. I just recently got this new phone because mine had died so I assume maybe it's from the newer version or updated version for the Samsung Note 5. Hope this helps someone.
