Security Master Customer Insights

1. The app looked good, but due to all of the ads I've had to find something else (to complete 1 task in this I had to watch 10 lengthy adverts! Thats 20 minutes of my life I'll never get back!)I was a bit scared at first when I suddenly came across the app on Opera news and I tried many times to bypass it, but it refused to go.

2. will follow up with more of a review once I've tried the app out further.Have never been able to get all the way through this app to completion! Get through 2 or three stages then I get a commercial, & after either canceling or watching till completion.

3. When done with the Commercial the app starts over again! If I can't complete a full set of cycles/stages, then it is of no use to me! Wasting memory, time, & battery power‼️ And again I tried.

4. It offers laconic and user friendly interface that allows to understand the main features of the application even for those who are far from the realm of technology.

5. Looking at the other negative reviews, if it doesn't steal your data, it probably does what it claims, but is so full of ads it's impractical to use.

6. Only getting through 3 stages & locked up! Unless something is done this app will be deleted! Well no response❕ So deleting‼️I only installed it so I could review it.

7. will request access to your media files, and require your approval through out each 15 scans, but the app so far has no issues as far as I can tell.

8. I was googling somthing and I got stuck on their spam ad.... My *device name* needs secured.

9. Awful introduction.15 scans are ran during the initial install and start of the app.

10. Security Master is a reliable ALL-IN-ONE solution for all your device’s needs.

11. It's a very good app for sure.This is an App that I was forced to install.
