Which mobile OS is most secure?

Blackberry used to be the default choice when looking for the most secure mobile device, but Blackberry has nearly disappeared from the market at this point. I also have to think that both iOS and Android have made progress in this area over the past couple of years, and I suppose there is also Windows Phone to consider, although it hasn’t been a very popular choice. Is there still a difference between mobile OSes when it comes to security?
Blackberry is still good. iOS is good-- only when the Apple Store testers are watching what they're doing, as they make mistakes that have caused huge vulnerabilities in iOS user devices. Android, sadly, is number three as it's easy to defeat security and load apps from sites where applications may have been easily tampered; unless jailbroken, Apple's delivery methods are better. Any jailbroken device is a "wildcard" because protections have also been broken.

No one knows about Windows 10, and little information is available in the US about Symbian or Tizen devices because there are few of them in the US. Summary: iOS.
Undoubtedly iOS is the best among all others. The major reason behind that is 'closeness' provided by Apple. That makes it nearly impossible to mess up the OS by doing wrong things with it, either inside an app or by a experimenting user.
Even though I'm personally an Android user, I'd say that Apple is generally the more secure choice for businesses, and are most commonly adopted by enterprise users. I don't know any businesses that still use BlackBerry around here, or Windows Phone for that matter, so I can't say much about them.

I think the main disadvantage that Android has versus iOS when it comes to security is that there are too many potential roadblocks to security updates. Google can issue a patch, but OEMs and carriers can delay getting it to customers for weeks, leaving a known vulnerability unpatched for an unacceptable period of time.

Google is trying to address this, and each new version of Android gets tighter and tighter integration with Google Play Services, which allows Google to bypass the roadblocks, at least in part, and push out OTA updates directly. They are also pushing out Android for Work, which basically partitions the work part of your device to keep it safe from the personal part. Oversimplified, I know, but you get the idea.
