1. Question remains: Does NQ still have access to my phone??I've been using NQ mobile security for about ten years now; it's a great and reliable antivirus and cleaner.

2. 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.Keep up the good work and malware features and speed up the scanUsed this app for many years without issue.

3. Feel unprotected, due to out of date virus database, so replaced it with another app.This is the absolute best portable smart phone and portable smart tablet security app.

4. I want screen overlays for some apps that I like and for apps that require it.Good, but way too many adsA few years ago I purchased this app and it was great for mobile protection.

5. However, for the last 6 months, have not been able to update the virus database.

6. I haven't been able to update virus scan.

7. That malware most popular antivirus I downloaded couldn't detect, NQ detected it without waste of time, and was fixed and deleted.

8. I've had a virus on my phone for a year now and not one virus scanning app could ever detect it but this one did.

9. Thank you SO MUCH Netqin!!I've been using NQ for several years with no problems and loved it.

10. See ya later NQ!Virus database is out of date, watch video which never appears.

11. I am currently looking at Bitdefender or Norton mobile security options for my phone.
