My previous rating was a 4.5 This WAS a good-great app for keeping my phone safe & uncluttered with apps running in the background and deleting junk files. The most helpful function (for me) WAS the hot button that sped up various apps that I use (especially games). When I installed Nox Security on my upgraded phone (same model, more current year), that hot button was nowhere to be found. 🤬 Aaargh! Please bring the speed-up hot button.

I used to really like this app. But now it doesn't do what it used to do. Like, I have 61 open apps and now it only closes one at a time from within the app it's self on the Force Stop Button. Then you have to go back to the Nox app and do it again for the next app. Then also it doesn't keep them closed. When you check it again they are all running again. It used to be my only security and cleaner, now I'm uninstalling it.

too many ads! You think a security app would be ad free. Seems counterintuitive to me. Can't get through one scan without seeing too adds!
