I used this app for years and I thought it was the best anti-virus app I had ever used. Now it never updates., gets stuck on same number for cash deletion all the time no auto scan and has adds for a paid subscription. Obviously it is not a working app anymore. I think I should get a refund for at least 2 years. It is too bad because it was such a great app once.

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.
