I am having some troubles with my android phone. It's a Nexus 5 running CyanogenMod 11.
I once installed Clean Master from the Google Play Store and decided (non long after) to uninstall it.
The problem I have is that CleanMaster seems to be still installed as I can sometimes see some popups claiming that "CM Game Booster" could free some RAM/space whatever or even that my android phone is too hot (which is wrong).
I used the app '/system/app mover' from F-DROID to see if something was installed but I couldn't find anything (from user and system apps) related to Clean Master.
The problem is I gave CleanMaster root access (for '15 minutes') when I installed it.
How can I uninstall CleanMaster ?
The strangest thing is that CleanMaster was installed 3 months ago, uninstalled 1 week later and I only noticed those popups last week. As the popups doesn't disappear untill I quit it (or press clean.. which I don't do) I'm quite sure the problem was not here before last week and nothing was installed last week or the week before..
