As updates/new versions of apps go I quite like this one, (I had the 2018 version). With exception - that when you choose APP LOCK & you scroll down the list of apps, I cannot find my EMAIL APP ANYWHERE WHY???? It's on my list of everyday apps & it was on the app lock list, when I had the PREVIOUS version installed, so this is very frustrating/annoying 😠. It could also put the app itself at risk PLEASE DO SOMETHING about this, I might be forced into opting for another app. WHATSAPP's also AWOL!!

this is straight trash after the update. I had more features when I just had the previous hi security Lite. But when I went to update that app it gave me the full heavy version and it removed some of the previous features it always had. on top of that I just went to do a full scan and it said there was nothing at all to be fixed. Now I know that's wrong because I could clear out junk once an hour with what I use.. complete bs, uninstalling right now

I have used this App for years and I have been happy with the contents that it provides including very minimum adverts. With today's update the App is now filled with many adverts, some very loud advertisements telling me "Your Android is full, it's time to clean up!" when it's not! Also, I am now aware that this security provider are sending data to Facebook! Look in Facebook settings - under 'Your Facebook Information' then click on the new tab 'Off-Facebook Activity' :@ Now Deleted

Ah...yeah it didn't work for me...1)it made my phone heat up badly instead of cooling it down..2)every time I go in to cleanout the "bad"stuff, I had to scan it twice on everything!!..and 3) every time I go to charge my phone, instead of charging, it would go up to about 73 percent charged, and then it would start killing my battery and heat up my phone and the charge started going down!!! Uninstalled, gone, ka-poot!!! Thanx for the nightmares!!

I love it! User friendly and simple user interface. Perfect for what I need. Only complaint Is that it won't put shortcuts to my home page and there are no widgets to solve this problem. Would give it 5 stars if this option was fixed. Running on a Blackberry Key2.

The new update doesn't boost memory at all unlike past versions. I've used this for years and it now has LOTS of ads. I can live with the ads, but not the inoperable boost function. Please fix it or I'll be uninstalling the app

Was a great and trouble free app and seemed to work well, Until the annoying adds have been added when you come back off a page and it starts playing loud music and add, would be a 5 star feedback if it wasnt for that, Otherwise a good app.

A. G. u. Jan 29, 2019     

Basic utilities should not have ads, time-wasting "features," or other clutter. (Or be necessary at all if the operating system was any good in the first place.) Background automation is better.

Ian. B. Oct 7, 2019     

I really like the console and the 4 buttons to activate the antivirus part of the app. Plus the colors and the design looks better than a lot of the other apps! I give 5 stars for function and the great work done to your app.

This is a good app, but the boost doesn't work right. On the new Oreo operating system on some Samsung phones, it is not compatible. I had to uninstall it & reinstall something else. I may try it again once a new version comes out. Sorry 🐍

This app is good but the only problem I have with it is that the app lock doesn't lock the apps. I put app lock on messages and when I go on messages it doesn't show a password until after like 10 min then it shows, please fix this and I will rate 5 thank you.

A. G. u. Oct 29, 2018     

Quick efficient and us nothing like any other app regarding ads that annoy. It does the job and is the first of many aps for security that I've tried and can say so far, nothing but thumbs up for this. Thank you for actually making what is and does exactly what is expected rather than another wasted effort counting on false claims. Creating aps and ones to secure my phone is not a skill I have obtained nor want to in life , which is why I would like to trust those who claim to offer such a thing . However until yours , never were the claims true . Lovely is what I say and now it gives me time to write this for you!!

after an hour in idle mode of phone, I check running service but its not there means that app is close, that means no protection running in background because android pie closing "background apps without notification in status bar only" those app with "notifiction on status bar" can run without closing in background, thats why 1 star only.

Install the app. tried the applock additional feature then lock all my app but did not ask for pattern/pin. Open one app but Hi Security is asking for finger print. How can you read my fingerprint when you didn't ask/record it. No instruction on that one before landing on the applock page. Have to uninstall the app right away to have access with my installed app again. NOT SATISFIED USER!

Eri. S. Jan 12, 2019     

I was satisfied but now each time I try to clean junk files it stops and says Super Cleaner isn't working. I have uninstalled and reinstalled the app twice and it continues to happen. Now I am uninstalling for gpod.

A. G. u. Apr 19, 2019     

Best cleaner, booster, antivirus I've found. Few ads or at least less than anything I've used before and the ones that do pop up are easy to skip past real quick, a big plus!

Jam. L. Apr 13, 2019     

I haven't had to many problems with it yet I have had it for a few years now just like all app they need to be improved but overall I'm pretty satisfied with it i would like it more if it could clean junk but it tell me to add another app there should be one app out there that can do it all without having to pay for it I am just saying

A. G. u. Jun 2, 2019     

I lke this this app. ALOT because it's user friendly. In addition, it scan all the features on my phone, show me the potential risks & when I hit "CLEAN" it cleans the features that are at risk.

Joh. E. Nov 23, 2018     

Appears to be doing what I expect. Adverts annoying especially other security ones you end up downloading instead of fixing you're program of cleaning and checking.

Lyn. T. Aug 29, 2019     

I had Hi Security on my Android for a long time. I had to get rid of it. Why? It got all weird on me when I scanned my WiFi a few times and claimed that my router was a "thief." I checked the information label on my router and that's how found out who the "thief" supposedly was. Seriously, Hi Security? You permanently lost me as a customer due that dumb mistake.

Jil. C. Jan 26, 2020     

Its good. But this last update all of sudden ads galore. Not fan of ads that i gota watch. So i found diffrent security that doesnt force me to watch ads. Just cleans and protects.

Cza. M. Jan 19, 2019     

doesn't work unless you download other apps for example: cleaner, boost. so what's the point of using it if it can't stand alone. just a waste of space.

A. G. u. Mar 7, 2019     

this is an awesome antivirus app.plus, it doesnt charge you to use it. i can free memory, and the google add that your is at risk doesnt bug me anymore. very easy to use too.

W.T. F. Aug 1, 2019     

Seemed to work great . A pop-up screen started appearing every 2 to 3 seconds for some reason . Had to delete the app .
