5 ★ I wish it would stay active is there any way to make it work all the time with out having to go to it bc I can literally turn my phone off and when I turn it back on everything is open for anyone to get to
4 ★ I download this app on every phone I have. I love that I get intruder selfies emailed to me. This app helps keep my phone from lagging & over heating. & also protects what is important to me. It checks for hidden apps that you wouldn't know was there otherwise. Checks for viruses. Boosts your phone.. However, I don't like the ads & the pop ups that let me know it's been automatically scanned when it hasn't, just so I'll scan it. Over all it is a good app to have on your phone.
5 ★ A threat was found in a scan, all I had to do was tap one button and my problem was gone!! Great app*****
1 ★ Cannot put apps on whitelist, even though theres an option there but they do not allow me to choose apps on whitelist, even paid $17.99 for yearly subscription.... Trashy
5 ★ i like this app so much, i told quite a few people about it and how good it is. The wallpapers are amazing. But realize that id blocker is not on the last update😏🙄 CAN YOU PLEASE CONSIDER BRINGING THE CALLER ID BLOCKER BACK.🙄 PLEASE???🙁 love the app still even thou still dont have caller id blocker😕. My friend just got a phone and i told her about the app and how good it is she now has it on her phone. Thanks keep up the good work.
4 ★ I have been trusting this app for a WHILE, if I believed that I felt something not safe like my private information, I would download this app I would give it FIVE stars but everytime I open my phone, it would show how many days it protected my phone and how many apps it scanned, it doesn't really bother me, but I feel like I HAD to put FOUR stars. <3
1 ★ UNISTALLATION OF THIS APP!!! I used this app for quite a long time and it has supported me all through. the main reason I unstalled this app was for the app lock,I wanted to keep my apps safe. Its my vacation time and now when I want to uninstall this app,I'm not able to do it. I really want to uninstall this app bcoz my apps are safe(as its vacation),but I'm not able to do so.Can any1 tell how to uninstall this app! P.S-I am giving it a one star rating so that its more noticable.
3 ★ Can't control what it does and when; most recently it keeps turning the VPN feature on, I disconnect when at home or work because it interferes with one of my apps significantly and others somewhat, but then it keeps turning itself back on. I want to conrol when it's on and when it's off but it won't let me.
4 ★ it's kinda laggy at times, and there are a few things that could be worked out better. other than that, it's AMAZING. I feel so much safer that my identity and stuff is well protected. the protection can be irritating, but that comes with the protection. fantastic app!
1 ★ I gave you 3 star rating befor this...but u didn't solve my problem about app hibernation function...hibernate app function is not working properly... hibernated apps start automatically itself and drain bettery...this is happening since sometimes...please fix this problem and make app hibernation more powerful to save bettery...
5 ★ This App is awesome! For a long time I ve been using a differ antivirus not knowing that i had many issues (threats) in phone until when I installed this antivirus that eliminated them all. its so amazing, i think this is good for me and I recommend it to anyone to use.
2 ★ It worked great at first. Its been one year since i first installed this app. But now it stops suddenly and even on updating it, the open option is not accessible. It is not even opening. How will i access my private? If i uninstall it, my data will be lost forever.
4 ★ i am using this app last 7 years .it has amazing features. This does all as says its having a feature for call recording i love this feature but i recently update before two days and again update today but the feature for call recording is missing . i am highly disappointed .OVERALL ITS very good .
4 ★ This app is genuinely good for andriod phones, but the really annoying part is it keeps telling you to scan or clean your phone even if you just did a few days ago. overall, this is a pretty good app to maintain your phone.
1 ★ This app is irritating so much. Now I am trying to uninstall it but it is not uninstalling. even though i have deactivated it before uninstalling. this app is manipulating us .As far as i am concerned never install it guize !!!
