Ratings and reviews

I've been using NQ mobile security for about ten years now; it's a great and reliable antivirus and cleaner. However, I gave the app only 4 stars because the developer has intentionally made it impossible to update the app. I don't understand why something as simple as updating an app became a premium feature, and even when you try to upgade to the premium package, all you get is connection error or server down.

Used this app for many years without issue. However, for the last 6 months, have not been able to update the virus database. It used to cost £1 to update, on a more or less monthly basis, which was fine. Now all I get is a message saying "unable to connect, try again later". I am always connected to wifi when I do this so I'm unsure why a connection is unsuccessful. Must be an issue with the app itself. Feel unprotected, due to out of date virus database, so replaced it with another app.

Used to be reliable for backing up contacts but will no longer let me backup new ones. For a while now, it's been hard to tell what else this app is even doing. Won't allow updates on a second device even if you're subscribed and I can't update my subscription. Icon won't go away. No customer support response to help improve the three star review I gave over a year ago when at least contacts could be backed up. Now that that no longer works, this app is completely useless. Uninstalling.
