Too many ads. It's constantly alerting me that my cpu is overheating. Can you imagine having an alert pop up every 30 minutes? So annoying. My cpu really can't be overheating all day every day. My phone doesn't even feel hot. When I cool it down it doesn't seem to help the issue. There always seems to be junk that the app needs to get rid of when I just recently did a scan to clean it. This app seems fake, like it doesn't do anything. The entire app seems like a lie.

There's something weird going on with this app! Lately, when I get a pop-up telling me I need to perform a certain action (ie "boost memory), as soon as I tap the button to perform the designated function, the music from an add starts playing in the background, and enters what is known in computer terms as, "an endless loop", or in the pre-mp3 days, it would be called, "a broken record." The only way to put a stop to that now obnoxious music is to RESTART my phone!!!!

This helps me get a head start. It really helps protecting my phone in case if there's malicious stuff going on my phone. If I see one, I could clean it to make sure my phone don't get hacked or completely destroyed. But not sure if there's any bugs or crashes in this because there's other security apps that have bugs and crashes in them, well some. But at least this app still work properly though, even though I just have to make sure that this app doesn't have bugs in it, that's all I have.
