I have a phone running Android 5.1, and something strange is going on. There is an Android system file that is com.mplore.ads.popup , or at least says it is an Android system file. It is 6.63 MB. It says it is on the SD card with that greyed icon, yet I do not have a SD card in the phone. I just saw it a few minutes ago. One or two days ago, not there. Huh. Please help! Storage info available if you need it. Oh, yeah, I downloaded a ap from the Google Play Store called System Repair 2018 to see if I could free up storage with it four or five days ago, ran it seems day, had good ratings. Also a partial run. Help!
