I used to appreciate this app because it worked everytime for a couple of years. Just now it asked for permissions again wherein my phone notes at the setting "app not working correctly". After giving permission this app notes that 27 other apps open in background. After the usual advertisement that was OK with me since app was free and gave what I needed, I started as usual and it did nothing like before. I too I had to hit the back button all thru 27 apps info but it didn't close them. Ouch.

A few minutes ago I closed 83 apps using your app but when I again scan for running apps it shows 83 apps still running. Then what did your app do? From your quick response it is understood this app is useless.
